Researchers pack a "quantum light factory" into a 1mm² CMOS chip — combines photonics, electronics, and quantum hardware with traditional silicon manufacturing that can achieve mass scale

Researchers from Boston University, UC Berkeley, and Northwestern University have created something that sounds straight out of a sci-fi movie: a 'quantum light factory' squeezed onto a 1 mm² silicon chip. Built using a standard 45 nm CMOS manufacturing process—the same kind used for standard x86 and ARM processors—this breakthrough brings quantum hardware a step closer to the world of mass production. The work, published in Nature Electronic, could pave the way for scalable quantum computing that doesn't require exotic setups, instead relying on mass production techniques that we already employ today. Think of this chip as a prototype for a future quantum factory line. It packs 12 tiny silicon loops, called "microring resonators," each acting as a generator of photon pairs with special quantum properties. These photon pairs are the lifeblood of many quantum technologies, but producing them usually requires fragile lab setups. Here, they're generated directly on a chip no bigger than a fingernail. What makes this remarkable is that the chip doesn't just produce quantum light; it's more about keeping that light stable. Microring resonators are powerful but temperamental—small temperature changes or manufacturing quirks can throw them out of tune, halting the photon flow. To solve this, the researchers built a feedback system directly into the chip; each resonator has a tiny photodiode to monitor its performance, along with miniature heaters and control circuits that adjust it on the fly. This self-tuning approach means all 12 resonators can work together in perfect sync, without the bulky stabilization equipment usually needed. 'This is a small step, but an important one,' said Miloš Popović, associate professor at Boston University and one of the senior authors. 'It shows we can build repeatable, controllable quantum systems in commercial semiconductor foundries.' That's the real story here—this isn't just a niche, bleeding-edge lab demo, but proof that quantum chips can be made with the same industrial techniques used to build CPUs and GPUs. Of course, quantum computing is nowhere near the maturity of standard semiconductors powering our devices today, but this is a step closer to that eventuality. Let's talk about the most important revelation. The team's choice of CMOS (Complementary Metal-Oxide-Semiconductor) is a game-changer. CMOS is the backbone of modern electronics, used by companies like TSMC to mass-produce everything from smartphones to supercomputers. While the 45 nm node used here isn't cutting-edge, it's proven, cost-effective, and compatible with the vast infrastructure of silicon manufacturing. The chip was built using a platform co-developed with GlobalFoundries and Ayar Labs, a company already leading the charge in optical interconnects for AI and high-performance computing. This overlap with the AI world is no coincidence. Nvidia CEO Jensen Huang recently called out microring resonators—like those on this chip—as key components for scaling AI hardware via optical connections. This new research shows that the same photonics technology could also unlock scalable quantum systems. It's not hard to imagine a future where quantum and AI hardware share similar silicon platforms. Moreover, Nvidia is already heavily investing in this field, so we can only expect development to ramp up. The term 'quantum light factory' isn't just for flair, either. Just as classical chips rely on streams of electrons and optical networks depend on laser light, future quantum technologies will need a steady supply of quantum light. By proving that these quantum light sources can be built, stabilized, and replicated on silicon, the team has shown that quantum hardware can move beyond one-off experiments and into something that can be scaled like traditional computing. Some of the researchers involved are already taking this expertise into industry roles. Team members have joined companies like PsiQuantum, Ayar Labs, and Google X, all of which are betting heavily on photonic and quantum technologies. It's another sign that this field is moving rapidly from academic research to real-world products, even if they're sometimes more fun-oriented than revolutionary. Backed by the National Science Foundation's Future of Semiconductors (FuSe) program, the Packard Fellowship, and the Catalyst Foundation, the project shows how far interdisciplinary collaboration can go. Photonics, electronics, and quantum optics are worlds apart, but this chip proves they can be brought together on a commercial platform. If Intel's 4004 microprocessor marked the start of mass-produced computing power, this 1 mm² quantum light factory could be remembered as the first step toward mass-produced quantum hardware. What once needed an entire lab bench now fits onto a silicon wafer—and that's a leap worth paying attention to. Who knows? Maybe a decade from now, you'll be seeing a new TSMC competing for quantum computing excellence, especially now that there's already an operating system for it out there.

Shocking truth behind Korean star PSY revealed: 'People thought I was a gangster who decided to become a singer'
Back in 2001, when a tough-looking rookie singer appeared on Korean stages, everyone assumed he was some ex-gangster trying his luck in entertainment. The guy had that rough edge, spoke boldly, and didn't fit the typical clean-cut idol image. But here's the shocking reality - this was Park Jae-sang, better known as PSY, and he came from one of Korea's most influential business families! Turns out, our man PSY wasn't from some rough neighbourhood. He was actually a proper rich kid from Seoul's posh district, Banpo-dong. His father? The CEO of a major semiconductor company worth around Rs 3,200 crores, and his mother ran an upscale restaurant in Gangnam. The gangster rumours were so widespread that PSY had to publicly address them, saying, "People thought I was some gangster who got too excited and decided to become a singer. " From Silver Spoon to Global Superstar But here's what makes PSY's story is fascinating for as this wasn't just another rich kid coasting on family money. This rebel actually dropped out of Boston University where he was studying business, because music was his true calling. Against his parents' wishes, he enrolled at Berkeley College of Music, then returned to Korea to revolutionise the music scene with hits like "Bird" and "Champion." by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like This Could Be the Best Time to Trade Gold in 5 Years IC Markets Learn More Undo The interesting part? PSY actually benefited from those wealthy family rumors. When asked about being called a "business tycoon's son," he cleverly responded, "I'm not from a business empire, but thanks for making me one! I don't correct rumors that work in my favour. " Then 2012 happened, and "Gangnam Style" exploded globally. This wasn't just a hit - it was a cultural phenomenon that reached #2 on Billboard and made the whole world dance to a Korean tune. Suddenly, those old gangster rumours seemed absolutely ridiculous. The Hidden Price Now here's where the story gets serious, especially for us who understand the pressure of constant performance. Behind all that energy and those incredible shows, PSY was literally destroying his body. His signature summer concerts, called "Soaking Show" (Heumppeok Show), were basically endurance marathons disguised as entertainment. PSY himself admitted, "I've almost collapsed on stage because I couldn't breathe, and it's happened multiple times." The man was giving everything, sometimes to the point of vomiting or being carried off stage after shows. They explained that such intense physical performances can cause irregular heartbeat, blood pressure issues, and chronic inflammation. Add the water-soaked environment messing with body temperature, plus lack of sleep and poor eating habits, and you get serious health problems, including fatty liver, gastritis, and fainting spells. Learning to Survive Success The wake-up call was real. PSY, who had gained weight to over 90kg and was dealing with joint pain and stomach problems, realized he needed to change his approach completely. The guy who seemed invincible was human after all - something every hardworking Indian can understand. These days, PSY's still performing, but he's doing it intelligently. He's committed to walking over 10,000 steps daily (like our fitness-conscious uncles!), switched from sugary drinks to electrolyte solutions before and after concerts, and completely changed his diet from high-carb junk to vegetables and lean protein. His new rule? Nothing but water after 10 PM. Fans have noticed he looks much slimmer and healthier.

Four-day working week: The new evidence igniting push to extend weekends
Extending the weekend could be the recipe for improving employee health and the secret sauce to boost business productivity. A large-scale, peer-reviewed study has found a four-day working week could reduce employee burnout and improve job satisfaction. But the research released also found that working fewer hours improved their workplace performance, according to insights gleaned from more than 500 Australian and New Zealand employees. The findings released on Tuesday follow a series of significant trials of four-day working weeks in nations including the UK, Canada and Germany, and after the Greens proposed a national pilot program during the federal election campaign. The research by academics at Boston University and published in the Nature Human Behaviour journal investigated experiences at 141 companies testing four-day working weeks with no reduction in employee pay. The companies across Australia, New Zealand, Canada, Ireland, the US and UK prepared for the trial by reorganising their operations and eliminating low-value activities such as 'unnecessary meetings' for two months, before reducing workers' hours. Workers less likely to suffer burnout Researchers led by Wen Fan and Juliet Schor compared the experience of the 2896 employees to a control group of employees working a typical five-day week. After six months, those who spent fewer hours at work were less likely to suffer burnout, had a higher rate of job satisfaction and better mental and physical health. 'We find that work time reduction is associated with improvements in employee wellbeing - a pattern not observed in the control companies,' the study said. 'Across outcomes, the magnitude is larger for the two work-related measures - burnout and job satisfaction - followed by mental health, with the smallest changes reported in physical health.' Improved performance and productivity Reducing work hours also improved performance and productivity, the employees reported, due to lower levels of fatigue and fewer sleeping problems. Companies that reduced weekly working hours by eight experienced the biggest gains, the research found, although modest improvements were observed with reductions of between one and four hours. While the study mirrored findings from similar research, University of Otago academic Paula O'Kane said it provided more evidence that boosting productivity did not necessarily mean boosting workloads. 'Traditionally, time spent working is used a proxy for productivity when, in fact, better rested and healthier people can be more productive in less time,' she said. 'While the study centred on a four-day week, the broader implication is clear: flexible and potentially individualised working arrangements can deliver similar benefits.' The findings come as the federal government prepares to hold its Economic Reform Roundtable in Canberra to investigate ways to boost Australia's productivity and create a more sustainable, resilient economy. Labour productivity fell by one per cent in the year to March, according to the Australian Bureau of Statistics, even though the number of hours worked rose by 2.3 per cent.
