TL;DR

Senators Gary Peters (D-MI) and Marsha Blackburn (R-TN) rolled out the National Quantum Cybersecurity Migration Strategy Act to make sure the feds aren’t caught off-guard when quantum computers get powerful enough to crack today’s encryption. The bill taps the White House Office of Science and Technology Policy and the Quantum Science subcommittee (ESIX) to craft a nationwide roadmap for shifting all federal systems to quantum-proof security standards before it’s too late.

They’re even kicking things off with a pilot program: each agency must move at least one high-impact system to quantum-safe encryption, while ESIX pinpoints the most urgent targets, lays down performance benchmarks, and defines exactly what counts as a “quantum-relevant” computer. It builds on the 2022 National Quantum Initiative and the Quantum Cybersecurity Preparedness Act—but makes it mandatory instead of optional.

‘Neglected’ particles that could rescue quantum computing

USC researchers show how to turn quantum system into universal computer.

today.usc.edu

TL;DR

USC mathematicians have found that by dusting off a once-discarded particle—nicknamed the “neglecton”—they can supercharge Ising anyons and turn them into a truly universal quantum computer. Topological quantum computing normally uses braiding of Ising anyons to perform only a limited set of Clifford gates, but adding this single stationary neglecton (from a richer, non-semisimple math framework) completes the toolkit so you can braid your way through any quantum algorithm.

What’s even cooler? The team managed to sidestep the usual mathematical headaches (like broken unitarity) by quarantining the weird parts of their theory and making sure all the real “computing rooms” stay stable. This breakthrough not only shows the power of abstract math in solving real-world engineering puzzles but also points experimentalists to hunt for platforms that host this new anyon—bringing us a leap closer to robust, universal quantum machines.

Bitter fight over 2020 Microsoft quantum paper both resolved and unresolved

Bitter fight over 2020 Microsoft quantum paper continues • The Register

The journal Science is scrapping its 2021 “editorial expression of concern” over a five-year-old Microsoft quantum-computing paper and will issue a correction instead, saying the authors simply under-documented how they tuned their devices and didn’t catalog every bit of data. Lead author Charles Marcus calls it a vindication (if bittersweet after four years of scrutiny), but critic Sergey Frolov—who first flagged cherry-picked data—still insists a full retraction is warranted because the flaws “undermine the conclusion.”

This spat over Majorana-based topological superconductivity highlights a bigger headache in quantum-computing R&D: unverified claims, peer-review drama and accusations of data cherry-picking. As Microsoft races to turn its Majorana 1 chip into a real product, skeptics note that unlike your microwave (which you can test by cooking dinner), there’s no easy way to prove a working quantum computer—so disputes over reproducibility and publishing etiquette are only going to get louder.

TL;DR

Kory Becker’s 8-minute tutorial kicks off with a super approachable intro to quantum computing—no heavy math required. You’ll learn the basic difference between a classical bit (0 or 1, think light switch off/on) and a qubit, then write your very first quantum program that actually outputs numbers.

What’s Inside

– A clear analogy: bits as on/off switches (0 = OFF, 1 = ON)

– A step-by-step guide to creating and running a qubit-based “hello world” in quantum land

– Hands-on code examples so you can dive right into the magic of superposition and measurement

Science is set to swap out its 2021 “editorial expression of concern” over Microsoft’s 2020 paper on topological superconductivity for a milder correction, noting the authors didn’t fully disclose how they tuned their devices or catalogued all their data. Charles Marcus, a co-author and former Microsoft Quantum Lab director, is relieved—and a bit miffed at losing four years of his life—after multiple inquiries (including one by Copenhagen’s research-ethics committee) cleared him of wrongdoing.

But Sergey Frolov, the physicist who first flagged the paper’s shaky tunneling-spectroscopy results, isn’t satisfied: he thinks the work merits retraction, not just a footnote. The spat echoes wider doubts about Microsoft’s Majorana-based quantum computing claims and underlines how hard it is to police high-stakes research when the technology itself remains largely unverified.

China's SpinQ Targets 500-Qubit Milestone as Quantum Computing Nears Real-World Utility

SpinQ Aims for 500 Qubits as Quantum Computing Race Accelerates

China's SpinQ plans a 500-qubit machine, accelerating real-world quantum computing with superconducting chips and global exports across 40+ countries.

semiconductorsinsight.com

China’s SpinQ is betting that within three to five years, a 500-qubit quantum computer will finally break into real-world use, tackling chemistry, logistics and cryptography problems classical machines can’t. Founded in 2018 in Shenzhen’s Hetao zone, SpinQ has already shipped everything from three-qubit NMR demo rigs to 20-qubit superconducting systems—and even China’s first exported superconducting chip. They expect a 100-qubit box by end of 2025, but say fidelity and coherence have to improve big time before quantum advantage becomes practical.

While SpinQ rakes in sales across 40+ countries and just closed a hefty Series B round, its CEO admits China is still about three years behind the U.S. in the quantum arms race. Google’s 105-qubit “Willow,” Microsoft and Amazon’s mini-chips, and IBM’s fault-tolerance roadmap all show how fierce competition is heating up—but with solid government backing, new university programs and dedicated industry parks popping up, China’s ecosystem is turbo-charging its bid to catch up.

CMOS Chip Controls Spin Qubits at 100mK - Australia Breakthrough

University of Sydney team builds first CMOS chip to control multiple spin qubits at ultralow temps, solving key bottleneck in quantum computer scaling.

semiconductorsinsight.com

Australian scientists at the University of Sydney, led by Prof. David Reilly, just pulled off a world-first: a tiny CMOS “chiplet” that lives at 100 mK and wrangles multiple silicon spin qubits using only microwatts of power. By baking the qubit control electronics right into a cryogenic-friendly CMOS package, they’ve ditched the bulky, heat-pumping wiring and room-temperature gear that’s been the scaling bottleneck for quantum machines.

In tests, their two-chip prototype (one CMOS controller + one spin-qubit chip) nailed two-qubit entangling gates with zero extra quantum drama—“the qubits hardly notice the switching of 100,000 transistors next door,” as Reilly jokes. This breakthrough paves the way for monolithic or chiplet-based quantum-classical integration, bringing the dream of millions of silicon qubits and industrial-scale quantum computers a big step closer.

China's SpinQ plans a 500-qubit machine, accelerating real-world quantum computing with superconducting chips and global exports across 40+ countries.

semiconductorsinsight.com

China’s SpinQ reckons practical quantum computing is just around the corner—about three to five years away—once systems hit roughly 500 qubits. Founded in 2018, the Shenzhen startup already offers everything from 3-qubit desktop NMR rigs to 20-qubit superconducting machines, and plans to ship a 100-qubit system by late 2025. CEO Xiang Jingen likens the field to early-era semiconductors, saying quantum won’t replace classical computers but will turbocharge tasks in chemistry, logistics and crypto once qubit quality, coherence and error correction reach the sweet spot.

SpinQ’s gear has sold in over 40 countries, and it just closed a hefty Series B round to fuel R&D. While China still trails the U.S. by a few years, its Hetao and Hefei quantum hubs—home to research centers and startups—are buzzing with activity. Google’s 105-qubit Willow, Microsoft and Amazon’s smaller chips, and IBM’s 2029 fault-tolerance goal show the global race is on, and SpinQ wants to be one of the front-runners.
