New Paper Alert: “Low‑Overhead Transversal Fault Tolerance for Universal Quantum Computation”
A new fault-tolerance framework unveiled by researchers from QuEra, Harvard, and Yale promises to drastically reduce the time overhead of quantum error correction. Published yesterday in Nature as “Low‑Overhead Transversal Fault Tolerance for Universal Quantum Computation” (Zhou et al., 2025), their method - called Transversal Algorithmic Fault Tolerance (AFT) - eliminates the usual slowdown from repeated error-checking cycles. By cutting this…

Caltech’s 6,100-Qubit Optical Tweezer Array: A Quantum Leap in Scale and Coherence
In a new quantum computing milestone, Caltech physicists have created the largest qubit array ever assembled: 6,100 atomic qubits held in place by laser “tweezers.” This far exceeds previous neutral-atom arrays, which contained only hundreds of qubits. Even more impressive, these thousands of qubits were kept in a fragile quantum state (superposition) for about 13 seconds - nearly ten times…

New Paper Alert: A Relational Critique of Bell Locality
Just a few days ago Waaijer and van Neerven published a paper "A Relational Critique of Bell Locality" in which they analyze Bell experiments through the lens of relational quantum mechanics (RQM). For decades, Bell's theorem has been seen as proof that nature is fundamentally nonlocal. Any theory that respects relativity and allows free choice of measurements must obey the…

New Paper Alert: Brace for Impact: New ECDLP Challenge Ladder Benchmarks Quantum Threat to Bitcoin
The “Brace for Impact” ECDLP challenge suite is a great attempt to translate a looming cryptographic crisis into a concrete set of problems we can grapple with today. It provides a much-needed “ruler” to measure where we stand in the race between encryption and quantum decryption. The choice of Bitcoin’s secp256k1 curve for these challenges ties the abstract math to…
