China's Origin Quantum upgrades its software for chip debugging
The Hefei-based Origin Quantum, or Benyuan Quantum, has launched its fourth-generation QCCS, Benyuan Tianji 4.0, which supports more than 500 qubits, according to the Anhui Quantum Computing Engineering Research Center (AQCERC).
Guo Guoping, director of research and chief scientist at Origin Quantum, said the launch of Benyuan Tianji 4.0 indicates China's quantum computing industry now has replicable and scalable engineering capabilities, laying a solid foundation for the mass production of quantum computers with hundreds of qubits.
The qubit, or quantum bit, is the unit of the fundamental unit of information in quantum computing. The higher the qubit, the faster a quantum computer.
However, as different quantum firms use different definitions, it isn't easy to directly compare the performance of superconducting quantum computers in terms of their qubits.
IBM Quantum Heron 2, dubbed the world's fastest quantum computer, has 156 qubits. Google's Willow quantum chip features 105 qubits. Origin Quantum's Benyuan Wukong, launched in January 2024, has 72 qubits.
A McKinsey report last year predicted that quantum advantage, a situation in which quantum computers can solve problems much faster and more efficiently than classical computers, will happen around 2027-2030. By 2035, annual revenue from quantum applications in chemicals, life sciences, finance, and mobility sectors could reach $2 trillion.
To boost the number of qubits, engineers need to manually debug physical qubits. They must also use software to correct every physical qubit's error to create logical or usable qubits.
'The Benyuan Tianji 4.0 system is built entirely on China's self-developed hardware and software,' said Kong Weicheng, deputy director of AQCERC and head of the Benyuan Tianji 4.0 development team. 'This enables more efficient control and precise quantum chip readout, significantly reducing quantum computer research and delivery cycle.'

He explained that Benyuan Tianji 4.0 has four additional core software programs:
service management software (Naga&Venus),
superconducting quantum chip control software (Monster),
full-interface quantum chip control and analysis software (Visage) and
operating system connecting software (Storm).
Kong said Visage is the brain and can quickly detect qubits.
'Every qubit of a quantum chip needs to be debugged. Traditionally, a PhD-level expert may take more than one day to finish this process, making the debugging cycle too long for any quantum chip with more than 100 qubits,' he said. 'But with Visage, junior engineers can run standardized debugging processes for quantum chips more easily.'
US investment ban
Quantum computing can support scientific experiments, but it is also a sensitive technology that can break sophisticated encryption, create highly secure communication networks, accelerate supercomputers for missiles and drone navigation, enable quantum communications and improve AI model training.
In August 2023, US President Joe Biden signed an executive order restricting US investments in China's quantum computing, artificial intelligence, and semiconductor sectors. Last October, the US Treasury Department finalized the relevant regulations, which took effect in January 2025.
In recent years, China's state-owned funds have provided substantial financial resources to many quantum projects, encouraging local firms to build a complete supply chain and an ecosystem.
Origin Quantum and Chengdu Zhongwei Daxin Technology can make a wide range of quantum equipment. Footage showed that Origin Quantum imported lithographic machines from Germany's SÜSS MicroTec to make its superconducting quantum chips.
Origin Quantum develops its operation systems and software, following in the footsteps of IBM, which offers users a suite of tools such as IBM Quantum Platform, Qiskit SDK and Qiskit Runtime to run quantum computations.
The company launched its 72-qubit Wukong computer and the Benyuan Tianji 3.0 system in January 2024. Wukong has so far completed over 380,000 quantum computing tasks across various industries, including fluid dynamics, finance and biomedicine. It is now accessible in 139 countries and regions worldwide, with major international users in the US, Russia, Japan, and Canada.
Last month, Origin Quantum said it successfully used Wukong to boost the training performance of an AI model with one billion parameters by 8.4%. It said it also reduced the number of parameters of the AI model by 76%, which means an improvement in efficiency.
However, the China Academy of Information and Communications Technology (CAICT) said in a report that Chinese quantum computers are still far from being used in large-scale commercialized quantum computing.
'Most quantum technologies in China are just coming out of the laboratory, waiting for real applications and commercialization,' Jin Yirong, a researcher at the Beijing Academy of Quantum Information Sciences, told Xinhua.
'It created a chicken-and-egg problem as immature technologies lead to insufficient applications, which in return limited the development of the technologies.'
He said China lacks engineers specializing in quantum and classical computing, while local graduates can only fill half of the quantum-related job vacancies in the market.

Mixed views on sales at computer fair
Mixed views on sales at computer fair This year's Hong Kong Computer & Communications Festival will feature more than 200 local and overseas exhibitors. Photo: RTHK Vendors on Wednesday expressed mixed feelings about business prospects at the upcoming annual Hong Kong Computer & Communications Festival. The four-day fair, set to start on August 22 at the Hong Kong Convention and Exhibition Centre, will feature more than 200 local and overseas exhibitors, which is about 100 fewer than last year. Lok Ki Ki, marketing manager of Winco, the city's sole distributor of products by American router company Netgear, said it is taking a cautious approach to this year's sales targets. 'We hope we can keep the same amount [of sales] like last year and hopefully it won't be dropping a lot,' she said. 'Well, in general, the economy is kind of dropping down and it's really a tough environment for us and especially for gadget items and industries.' The company plans to showcase more middle and entry-level products at its booth to boost sales, she added. Another booth operator echoed the same cautious outlook, predicting sales would be 20 percent lower than last year. 'It's really according to the reaction of the public. When there are new product launches in this year. Even when NVIDIA launched new graphic cards, the sales didn't bump up too much,' said Saaleh Hafeez, product manager of MSI, which mainly sells gaming laptops. 'And the other reason is that this year we don't have any good game titles. So previously when there are good titles coming out, people will tend to go and purchase new laptops. But this year we didn't see this trend.' Some firms, meanwhile, remain optimistic, including Belkin, an American company that sells consumer electronics products. Associate director of marketing Crystal Chu said they expect a 10 to 20 percent year-on-year sales increase. 'Because recently we found out that there are quite a lot of accidents in the market. Lots of battery packs got into accidents, like explosions,' she said. 'And we realise that it's a very good opportunity for us to educate the customer and to let them know that we have the safest power bank or battery pack in the world.' The company is so confident about sales, it has put extra money into securing a prime booth at the fair, Chu added. Good Century, an authorised distributor for American memory card and USB drive company Sandisk in Hong Kong and Macau, also anticipates a sales increase of about 10 percent. To boost sales, many vendors said they will offer promotions at the fair, such as price cuts of more than 50 percent on a limited number of products and 'buy more, spend less' deals. The Chamber of Hong Kong Computer Industry added that it has also introduced more diverse content to the fair to attract visitors from different age groups. Highlights include a forum on AI trends, an e-sports competition, and a meet-and-greet session with the popular Taiwan-based cheerleading group Rakuten Girls. Nintendo will set up a booth featuring a gaming experience zone where visitors can try its new Switch 2 console. This year's fair will support 22 electronic payment methods, including Octopus, PayMe and cryptocurrency. Standard admission tickets for the fair are set at HK$35, while entry is free for tourists, children under 1 metre tall, people aged over 65 and holders of disability cards.

Taiwan readying 'carrier killer' missile to thwart China invasion
Betting on stealth over speed, Taiwan is forging a long-range 'carrier killer' to push back China's carriers and toughen the First Island Chain—even as layered Chinese defenses and shaky allied politics cloud the gambit. This month, the South China Morning Post (SCMP) reported that Taiwan is developing a long-range subsonic anti-ship cruise missile that defense analysts say could significantly strengthen deterrence against China's growing naval power, citing a defense ministry procurement list. Under the Defense Industry Development Act, the ministry will spend NT$40 million (US$1.3 million) over two years on 80 frequency-agile coaxial magnetrons, radar components for the new missile and existing models. Meanwhile, local media said more than NT$800 million (US$26 million) was allocated in 2021–2022 to adapt Hsiung Feng IIE land-attack technology with enhanced stealth. Taiwan's National Chung-Shan Institute of Science and Technology (NCSIST) is believed to have led the weapon's development since 2021. Analysts, citing the US AGM-158B and C as references, estimate the missile will have a range of 600–1,000 kilometers—enough to reach beyond Chinese carrier-based aircraft and cover large parts of the East and South China Seas. The new weapon aims to offset the Hsiung Feng III's 400-kilometer limit and the US-made Harpoon's 200-kilometer reach, both requiring risky penetration of the People's Liberation Army's (PLA) layered defenses. The timing highlights urgency, with two PLA Navy (PLAN) carriers exercising in the Western Pacific amid a years-long escalation since Beijing cut ties in 2016. China claims Taiwan as its territory, while the US remains Taipei's leading arms supplier, shaping the self-governing island's procurement and war planning. Jonathan Harman mentions in an October 2024 Global Taiwan Institute (GTI) article that domestic production of missile platforms offers Taiwan mainly quicker deployment and reduced costs for weapons that match the performance of US systems. Harman notes that Taiwan aims to replace specific US missile systems with its indigenous variants, although some still require improvements to serve as a more credible deterrent. In line with that, Taiwan's subsonic Hsiung Feng II is slower, more vulnerable to shipboard defenses and has a short range of only 120 kilometers. Although the Harpoon has a longer range, it remains a subsonic missile. The supersonic Hsiung Feng III may have a better chance of punching through shipboard defenses but lacks sufficient reach for standoff fires against PLAN surface groups. Together, these limits may explain Taipei's shift toward a stealthier, longer-ranged option. Taiwan's emphasis on a stealthy, long-range anti-ship missile may also reflect a change of philosophy in defeating shipboard air defenses. The AGM-158, which Taiwan may take as a design reference for its new missile, has a low radar cross-section and minimal infrared signature to evade modern ship defenses. In contrast, supersonic missiles try to 'outrun' interceptors, but they emit intense heat during flight, increasing detectability and engagement opportunities. The divergence captures two schools of thought about beating increasingly sophisticated naval shields. Underscoring just how formidable China's carrier defenses are, Daniel Rice notes in a July 2024 China Maritime Studies Institute (CMSI) report that its carrier battle groups employ three concentric zones. These include: An Outer Defense Zone 185–400 kilometers from the carrier, where J-15 fighters and submarines conduct surveillance and precision anti-air/anti-ship strikes, executing 'offense to enhance defense' A Middle Defense Zone, 45–185 kilometers away, where large surface combatants—Type 052D 'sword-carrying guards' with advanced radars and vertical launch systems (VLS), and Type 054A frigates acting as 'bodyguards'—focus on anti-submarine warfare and area air defense An Inner Defense Zone, 100 meters–45 kilometers from the carrier, where shipborne point defenses ring the flattop, which serves as the command-and-control (C2) hub. Taiwan's existing anti-ship missiles leave gaps that a new system aims to close. The Hsiung Feng II, Harpoon and Hsiung Feng III cover short to medium ranges. A longer-ranged, harder-to-detect missile would extend its sea-denial envelope. Further, Craig Koerner mentions in an October 2021 Global Taiwan Institute (GTI) article that Taiwan's asymmetrical defense strategy would leverage its terrain to deploy numerous ground-based anti-ship and anti-air missile units. According to Koerner, these units, concealed by camouflage and decoys, can target invading forces while avoiding detection. Koerner says this 'porcupine strategy' offers a cost-effective defense, reduces vulnerability to China's strikes and surveillance, and sustains deterrence. The regional picture trends in the same direction. Taiwan is not alone in pursuing land-based, anti-ship capabilities; US allies are normalizing distributed, road-mobile launchers to complicate PLA planning. For instance, Japan plans to acquire 1,000 upgraded Type 12 cruise missiles and host the US Navy/Marine Corps Expeditionary Ship Interdiction System (NMESIS), while the Philippines indefinitely hosts the US Typhon and NMESIS systems—moves that toughen the First Island Chain's anti-ship missile wall and create cross-pressures on PLA surface operations. However, this larger US strategy of containing China faces significant caveats. Eric Gomez argues in a November 2023 Cato Institute report that Taiwan's asymmetric strategy is less flexible than traditional capabilities in peacetime or gray-zone scenarios, but remains essential for deterring and surviving a Chinese invasion. Suppose the PLA blockades Taiwan with naval and air forces to cut off shipping without storming the island's beaches in an amphibious invasion; then, Taiwan's shore missiles have no clear target unless it escalates to firing the first shot. While a blockade may seek to force capitulation without fighting, Gomez says that approach often fails to achieve its aims, while pointing out that an invasion carries the highest risk but is the most likely approach to succeed. Masashi Murano points out in a March 2024 article for the US Studies Centre (USSC) that Japan's long-range strike capability faces critical gaps in support assets, munitions stockpiles, joint operational doctrine and persistent intelligence tracking. He adds that legal constraints and escalation risks further limit its ability to credibly deter nuclear-armed adversaries such as China through conventional counterstrike operations. Domestic politics can also reroute strategy. Derek Grossman warns in a July 2025 Foreign Policy article that shifting Philippine politics could upend US defense plans: Vice President Sara Duterte—the 2028 presidential frontrunner after midterm gains—could roll back President Ferdinand Marcos Jr's US alliance expansion, invoking the constitution's call for an 'independent' foreign policy and thus implicitly criticizing the US Typhon deployment in northern Luzon that has sparked Beijing's ire. Grossman notes she might follow her father's precedent by revisiting moves to terminate the Visiting Forces Agreement (VFA) and by curbing the Enhanced Defense Cooperation Agreement's (EDCA) now nine-site access, risking US access, training and surge capacity in the Philippines. Strategic bandwidth is another constraint. US involvement in overlapping conflicts—support to Ukraine, naval operations against the Houthis in Yemen, backing Israel versus Iran and responding to North Korea's nuclear saber-rattling—could sap political will and overstretch the defense industrial base, making US intervention against China's designs over Taiwan unfeasible if the timelines collide. Ultimately, Taiwan's deterrence hinges less on one 'carrier killer' than on whether Taipei can outlast a Chinese blockade while allied resolve from the Philippines to Japan—and US bandwidth—holds fast.

China having second thoughts on Trump's Nvidia chip deal
China has reportedly urged local firms, especially those for government-related purposes, to avoid using Nvidia's H20 chips for weeks due to national security concerns. Citing people familiar with the matter, Bloomberg reported on Tuesday that Chinese authorities have sent notices to companies over the past few weeks, discouraging them from using the less-advanced semiconductors. The report stated that Chinese officials are concerned that Nvidia chips may have location-tracking and remote shutdown capabilities. Nvidia has already denied this. The Financial Times also reported on the same day that Beijing is demanding technology companies explain why they need to order H20 chips, but not Chinese ones. The Information reported that the Cyberspace Administration of China (CAC) ordered companies, such as ByteDance, Alibaba, and Tencent, to suspend orders of Nvidia's H20 chips. According to the report, the government is investigating any potential security risks stemming from H20, while encouraging Chinese companies to purchase chips from local manufacturers, such as Huawei Technologies and Cambricon. Nvidia told the media in a statement that, as both the US and Chinese governments recognize, the H20 is not a military product or for government infrastructure. 'China has an ample supply of domestic chips to meet its needs. It won't and never has relied on American chips for government operations, just like the US government would not rely on chips from China,' said the company. On July 15, Nvidia's Chief Executive Jensen Huang said the company would soon resume H20 chip sales in China. On the same day, US Commerce Secretary Howard Lutnick said the H20 is only Nvidia's 'fourth-best' AI chip, which is slower than the fastest chips American companies use. He said the US wants to sell the Chinese enough AI chips that their developers 'get addicted to the American technology stack.' He said the United States' strategy is to stay one step ahead of what the Chinese can build. At that time, some pundits in China described the H20 chips as an irresistible 'poison wine' that would slowly kill Chinese AI chip makers by taking away their customers. Some others criticised the US for 'dumping' the H20 to China. Reuters reported on July 29 that Nvidia had placed orders for 300,000 H20 chipsets (worth about US$3.6 billion) with the Taiwan Semiconductor Manufacturing Company (TSMC) a week earlier. On July 31, the CAC said it summoned US tech giant Nvidia over security risks related to its H20. It said some US lawmakers have called for advanced chips exported abroad to be equipped with 'tracking and positioning' functions. 'The US did not unconditionally relax its export controls for the H20 chips,' a writer with says in an article published on July 23. 'It still does not allow the export of the high-end Blackwell chips. It seems to be saying that, 'I give you a sweet, but this is the last one.'' The writer says that the Trump administration has not yet altered its strategy to counter China, but has instead employed an alternative approach. He says the US side must demonstrate sincerity if it wants to maintain dialogue with China, obtain Chinese rare earths, and push forward with Trump's visit to Beijing in September. In an article, a Beijing-based financial columnist says that the US does not want to miss the opportunity to capitalize on the massive demand for AI chips in the country. 'The US government's lifting of the ban on the H20 isn't unconditional goodwill,' he says. 'Lutnick has explicitly stated that the US policy goal is to get Chinese developers addicted to American technology.' He says Lutnick's comments bluntly revealed the United States' intention to profit from China, while controlling its technological development. He says Nvidia will reportedly sell the B20, B30, and B40 chips to China in September, fueling the already-drastic competition between Nvidia and Huawei Technologies in China. 'In Huawei's labs, engineers are now testing the performance of Ascend 910B chip clusters,' he says. 'This chip can reach 320 TFLOPs (trillion floating-point operations per second) using FT16 (16-bit floating-point numbers) in speed to match the H20, while its price is 40% lower.' He says China will have more bargaining power in the global chip sector once its chips account for half of the Chinese AI computing market. In a press briefing on Monday, United States President Donald Trump explained why he agreed to restart the export of the H20 chips to China. He said that he had asked Nvidia for a 20% cut of the company's H20 chip sales to China, but ultimately, he agreed on only 15%. He stressed that the money will go to the US government, not himself. The same charge will also be applied to AMD, which sells MI308 to China. Trump also said he would discuss with Nvidia's Huang if Nvidia could reduce the performance of its Blackwell system by 30 to 50% for the Chinese market. 'That would be an unenhanced version of the big one [the most advanced Blackwell chips,' he said in a press briefing. 'We still sometimes sell fighter jets to a country, and we'll give them 20% less than we have.' In a February article, an IT columnist named Uncle Biao writes that Huawei planned to sell 100,000 Ascend 910C chips and 300,000 910B chips in 2025. 'Ascend 910C is a new generation AI chip, with its inference performance reaching 60% of Nvidia's H100,' he says. 'Besides, an inference service using DeepSeek R1/V3 and Ascend 910B has its performance reaching 80% of the A100.' 'Huawei uses its Ascend 910 series to break the Chinese market's dependence on Nvidia chips and become a significant competitor in the domestic market,' he says. He adds that Huawei is also building an AI ecosystem with its software tools, including MindSpore, the Atlas computing platform, ModelArts AI development platform, algorithm libraries, and Compute Architecture for Neural Networks (CANN). Huawei's CANN is a heterogeneous computing architecture for AI, aiming to break the monopoly of Nvidia's Compute Unified Device Architecture (CUDA). Key foundries (such as TSMC) and electronic design automation (EDA) software suppliers (such as Cadence, Synopsys, and Siemens) have already adopted the Nvidia CUDA-X and Blackwell platforms. On August 5, Huawei announced the full open-source release of CANN. It said the software serves as a bridge between high-level AI training frameworks and Ascend chips. Huawei's Rotating Chairman Xu Zhijun said that after seven years of development, CANN has achieved key breakthroughs in computing optimization, communication efficiency, and memory management. He said CANN can now provide computing power throughout the entire AI-model training and deployment process. Read: China fears Nvidia chips could track, trace and shut down its AIs
