Princeton Builds Qubit 3× Longer-Lived (1 ms Coherence)
A team at Princeton University has achieved a major leap in quantum hardware: a superconducting qubit that retains its quantum state for over 1 millisecond - roughly three times longer than the previous record. This coherence time of 1 ms, reported in Nature on November 5, marks the largest single improvement in qubit lifetime in over a decade. Longer-lived qubits directly translate…

Quantum Sensor Endures Extreme Pressures (240 GPa)
Quantum sensing is conquering extreme frontiers. Scientists have built a diamond-based quantum sensor that operates stably at pressures up to 240 GPa - about 2.4 million atmospheres, equivalent to the pressure in Earth’s core. This feat, reported October 30 by a team led by Qingtao Hao and colleagues, shatters previous records (which were on the order of 100-140 GPa) for quantum measurements…

Google Announces “Verifiable Quantum Advantage” on Willow Quantum Chip
Google’s 105-qubit Willow quantum processor was used to demonstrate a “verifiable quantum advantage,” performing certain calculations much faster than a classical supercomputer could. Google’s Quantum AI team announced that Willow executed a new algorithm called “Quantum Echoes,” which involves measuring subtle quantum “echo” signals in a chaotic system (technically known as out-of-time-order correlators). This marked the first time a quantum…

IonQ’s 99.99% Breakthrough and What It Means for Q Day
IonQ announced a new world record in quantum gate performance: >99.99% two‑qubit fidelity demonstrated on trapped‑ion hardware without ground‑state cooling. IonQ says the result comes from a new “smooth gate” technique developed by the Oxford Ionics team (now part of IonQ) and claims it will underpin 256‑qubit prototype systems in 2026 and a long‑term roadmap to millions of qubits by…

Unpacking the “Modular Quantum Factoring” Hype: Why RSA Isn’t Dead Yet
I’ve been inundated with messages asking about a recent paper titled “A Modular, Adaptive, and Scalable Quantum Factoring Algorithm.” On social media and even some press articles, this paper has been touted as a breakthrough - with claims that it dramatically reduces qubit requirements and possibly signals an imminent threat to RSA encryption. Understandably, CISOs in my network are alarmed,…

Quantum Sieving Breakthrough: Lattice Attack Exponent Slashed by 8%
A Dutch-led research team has achieved a significant breakthrough in quantum cryptanalysis of lattices. In an October 2025 paper "An Improved Quantum Algorithm for 3-Tuple Lattice Sieving" on arXiv, the authors report reducing the time complexity exponent for a key lattice attack from 0.3098 to 0.2846. In practical terms, this ~8% drop in the exponent translates to a theoretical speedup…
