Alice & Bob and Inria Cut Magic State Costs with New Method
We begin our weekly journey with Alice & Bob, a France-based quantum computing firm, and Inria, France's national institute for digital science. The two entities have reported a significant step in making quantum systems more efficient. Their joint team has developed a way to prepare 'magic states' using fewer qubits and less time. Magic states are a key ingredient for running advanced quantum algorithms.
The work uses 'cat qubits,' a type of superconducting qubit designed to resist certain kinds of errors. The researchers adapted a three-dimensional code into a simpler two-dimensional layout, which they call the 'Heart Code.' This design needs only 53 qubits to prepare a single magic state, an 8.7% drop compared with top competing methods. It also cuts the number of error correction cycles, making the process about five times faster while keeping the error rate below one in a million.
Importantly, the new method fits into Alice & Bob's current hardware, so it does not require new equipment. The result follows earlier work from the company that showed cat qubits could reduce hardware needs for large-scale quantum computers by up to 200 times.
Amazon Discloses Stake in IonQ
Amazon (AMZN) has revealed a $36.7 million stake in IonQ (IONQ) in its latest SEC filing. The position makes Amazon one of the largest known tech investors in a public quantum hardware company. IonQ builds quantum computers using trapped-ion technology, which offers strong connectivity between qubits.
The investment adds to Amazon's broader quantum push through AWS and its Braket service. IonQ's systems are already available to AWS customers. The disclosure has raised expectations that more cloud providers could compete for access to future quantum infrastructure. IonQ shares rose about 7% after the news.
Playground Global Backs Quantum Use Cases
At Deep Tech Week San Francisco, during the Playground Next-Gen Compute event, three seniors from PsiQuantum, Ideon Technologies, and NVision, all part of Playground Global's portfolio, outlined how they are applying quantum technology to practical problems. PsiQuantum, one of the most promising private quantum companies out there, with strong backers such as BlackRock (BLK), is developing a photonic quantum computer that will need at least one million qubits to tackle major tasks in chemistry and materials science. Ideon Technologies uses quantum sensors to scan the Earth's subsurface for critical minerals, while NVision applies quantum techniques to boost MRI scans for early cancer detection.
While their focus areas differ, all three aim to solve real-world challenges with quantum tools.
Japan Debuts Fully Domestic Quantum Computer
Now let's move on to Asia, as Japan continues to push for self-reliant quantum technology. It has launched a superconducting quantum computer built entirely with domestic components and software at Osaka University's QIQB. The system uses an open-source software stack called OQTOPUS. It will be on display for visitors to Expo 2025, where people can run simple quantum programs through a public interface.
The project involved multiple Japanese companies and research bodies, replacing imported hardware with local alternatives. It reflects Japan's push for self-reliance in advanced computing systems.
Quantinuum Partners with the UAE's Technology Innovation Institute
Quantinuum, backed by Honeywell (HON), has signed a deal with Abu Dhabi's Technology Innovation Institute to advance quantum research and applications in the UAE. The institute will gain access to Quantinuum's high-fidelity systems, including the upcoming Helios platform.
The partnership will focus on materials science, data encoding, and optimization. It will also train researchers to build algorithms, supporting the UAE's goal of becoming a global quantum hub.

Better Quantum Computing Stock: IonQ vs. Quantum Computing Inc.
Key Points IonQ and Quantum Computing Inc. are racing to develop tech that can overcome the challenges inherent in quantum machines. Quantum Computing Inc. employs photons as a means of building scalable quantum devices, and its sales may be on the verge of taking off. IonQ adopted ions in its approach, and the company saw second quarter revenue rise 82%. 10 stocks we like better than IonQ › The field of quantum computing is exciting. Quantum computers use atomic particles to perform complex calculations beyond the abilities of today's supercomputers, positioning them to revolutionize numerous industries. Many businesses are battling to produce technology that overcomes the challenges inherent in quantum machines. Two for investors to consider are IonQ (NYSE: IONQ) and Quantum Computing Inc. (NASDAQ: QUBT), which also refers to itself as QCi. These companies use different techniques to build quantum devices. IonQ employs ions to perform calculations while QCi utilizes photons. Between IonQ and QCi, one proves to be a better quantum computing investment right now. To understand which one and why, let's dive into both businesses in more detail. Where Quantum Computing Inc. is at today Current quantum computers are prone to calculation errors due to the delicate nature of atomic particles, preventing these machines from scaling up, and limiting their widespread use. Many quantum companies try to minimize errors by subjecting particles to freezing temperatures in expensive, bulky cryogenic equipment. Quantum Computing Inc. takes a different approach. It embraces the inherent chaos of harnessing these particles in a technique called entropy quantum computing. This method allows QCi's machines to operate at room temperature, use less power, and integrate with ordinary computer servers. Despite these advantages, its technology hasn't taken off. In the first quarter, QCi produced revenue of just $39,000. However, its Q1 operating expenses totaled $8.3 million. This chasm between income and expenses eventually will become a death knell for the business if sales don't pick up. But perhaps the company is turning a corner. In April, it sold one of its computers to a large automotive manufacturer, and in July, it secured a purchase valued at $332,000 from a major U.S. bank. The bank's sale is significant considering QCi produced revenue of $373,000 in all of 2024. IonQ's financial ups and downs IonQ's technology also operates at room temperature by using lasers to carefully control ions. It's been winning customers and growing revenue, a sign that its approach shows promise in surmounting quantum computing's shortcomings. In 2024, sales reached $43.1 million, up from the prior year's $22 million. But in Q1, the company's revenue of $7.6 million was flat year over year. This underwhelming result was not a good sign for a business with a Q1 operating loss of $75.7 million. Then in Q2, IonQ's sales trajectory changed once again. This time, revenue came in at an impressive $20.7 million, nearly double the prior year's $11.4 million. Part of this massive increase came from the company's recent acquisitions, as it works toward building a quantum computer network akin to the infrastructure underpinning today's internet. However, the acquisitions resulted in additional expenses, which catapulted IonQ's Q2 operating costs to $181.3 million, a huge increase over 2024's $60.3 million. Consequently, its Q2 operating loss ballooned to $160.6 million versus a loss of $48.9 million in the previous year. To bolster its finances, IonQ executed a $1 billion equity offering in July. This adds to the $1.3 billion in total assets the company exited Q2 with, while total liabilities stood at $168.2 million. Choosing between IonQ and Quantum Computing Inc. In deciding between these two quantum computing companies, one factor to weigh is share price valuation. This can be assessed through the price-to-sales (P/S) ratio, which measures how much investors are willing to pay for every dollar of revenue generated over the trailing 12 months. IonQ's P/S multiple is substantially lower than QCi's, indicating it's a better value. In fact, QCi's P/S ratio is so high, its stock looks overpriced. IonQ's superior sales growth and share price valuation make it a better investment over QCi in the emerging field of quantum computing. That said, buying IonQ stock carries risks, especially in the current macroeconomic climate, which could see inflation rise as a result of the Trump administration's aggressive tariff policies. IonQ's operating expenses are already accelerating, and the economic environment could drive those costs higher. While its balance sheet sports the funds to maintain operations in the short term, the longer-term picture remains murky. Whether IonQ's tech can achieve the quantum computing dominance it seeks is far from certain, and both it and QCi face large competitors with deep pockets, such as Microsoft, which is developing its own quantum computing solution. So only investors with a high risk tolerance should consider IonQ stock. Should you buy stock in IonQ right now?

These running shoes saved my achy knees — they're back in stock and on sale at Amazon
I love running. My knees, on the other hand, they're not always a fan. A few years ago I had a bad bout of runner's knee, which kept me from running for almost a year. When I started running again I switched my running shoes to the Asics Gel Kayano 30. Despite being old (they were released in 2023), they're one of the best running shoes I've ever used. For a limited time, you can get the Asics Gel Kayano 30 on sale for just $99 at Amazon. This is no longer Asics' flagship shoe, so it's hard to find in stock. If you can't find your size, I recommend clicking various colors till you find your size/color combo. Hard to find in stock, the excellent Gel Kayano 30 have been discounted to $99. These running shoes are designed to provide advanced stability and soft cushioning for neutral runners and overpronators alike. I've been using them for over a year and love how they're lightweight yet provide excellent cushioning and support. The women's shoe is also on sale for $96. Now priced at $124, this is the lowest prices we've seen on the Asics Gel-Kayano 31. Although they've been replaced by the newer Gel-Kayano 32, they're still an excellent shoe in Asics' popular stability line. Subtle updates include a more breathable upper and a new outsole material. The men's version is also discounted to $124. I've been using these shoes for almost two years now. (I loved them so much I bought a second pair months after buying my first pair). I find that they're great for casual runs on the treadmill, HIIT sessions, and long distance running outdoors. As an overpronator, I find they're great for runners who prioritize stability and want a smooth, plush ride. If you prefer to "feel the ground" as you run, these shoes probably aren't for you because Asics' PureGEL technology does a great job with shock absorption. Each foot strike is muted by the shoes' layers of foam so it feels as if you're running on clouds. I also like that the shoes are very breathable. They've remained dry even on my 9-mile outdoor runs in New York's hot, humid summers. Additionally, I normally opt for 2E width shoes, and with these Asics I feel the standard width is perfect for me. Along with mobility exercises, dynamic stretching, and working on my core — these running shoes helped me get back into my running routine stronger than before. Equally important, they've helped keep my knees from any injuries. That said, I wouldn't recommend these shoes as your everyday gym shoes. The extra cushioning is too distracting when performing squats or deadlifts. Otherwise, these are my current go-to shoes for stability running.

Real-time translation could be landing on your AirPods
What's happened? In a move straight out of Hitchhiker's Guide to the Galaxy, the latest iOS 26 beta suggests a real-time translation feature could be coming to your AirPods. First reported by 9to5Mac, the iOS 26 developer beta points to a new feature triggered by pressing both AirPods at once. The image shows words in English, Portuguese, French, and German. The feature is linked with the AirPods Pro (2nd Gen) and the AirPods (4th Gen). This is important because: Apple didn't mention a real-world translation tool during the WWDC 25 conference, but a Bloomberg report from earlier this year hinted that something similar could be in the works. Apple already offers a Live Translation feature for FaceTime, Messages, and Phone. The same functionality is available in devices from other brands like the Samsung Galaxy S24 series and later, as well as Meta Ray-Bans. A feature like this will likely run solely on the AirPods themselves, so it isn't clear what iPhones will support translation. It's likely it will be limited to the same devices that support Live Translation. Recommended Videos Why should I care? A real-world translation feature will make it possible to understand what someone says to you in a supported language, even if you don't speak it. If that person also has a device that offers translation features, your AirPods could function like the Babelfish technology, allowing you to hold a conversation in two different languages. Apple might be restricting the feature to the upcoming iPhone 17 lineup due to latency requirements. While Spanish isn't specifically listed in the preview, it is one of the languages supported by the Live Translate app (along with Korean, Italian, Chinese, and Japanese.)
