Oxford Achieves 10⁻⁷-Level Qubit Gate Error, Shattering Quantum Fidelity Records
Physicists at the University of Oxford have set a new world record for quantum logic accuracy, achieving single-qubit gate error rates below 10^-7 – meaning fidelities exceeding 99.99999%. The breakthrough, reported in a study published in Physical Review Letters in June 2025 marks the lowest error ever recorded for any quantum computing platform. “As far as we are aware, this…

Quantum Breakthrough Slashes Qubit Needs for RSA-2048 Factoring
A new research preprint by Google Quantum AI scientist Craig Gidney has dramatically lowered the estimated resources needed to break RSA-2048 encryption using a quantum computer. Gidney’s May 2025 paper, “How to factor 2048 bit RSA integers with less than a million noisy qubits,” argues that a fault-tolerant quantum computer with under 1 million qubits could factor a 2048-bit RSA…

New Study Shows Post‑Quantum Cryptography (PQC) Doesn’t Have to Sacrifice Performance
The new performance analysis of Kyber and Dilithium is a welcome addition to the PQC literature. It confirms that post‑quantum security and good performance are not mutually exclusive, especially when using optimized implementations. In fact, Kyber and Dilithium often outperform classical cryptography at comparable security levels. This challenges the narrative that PQC will drastically slow down our networks. At the…

Fault-Tolerant Quantum Computing (FTQC) with Erasure Qubits
Fault-tolerant quantum architectures based on erasure qubits represent an exciting development in quantum engineering. They blend clever hardware design with advanced error-correcting codes to tackle the Achilles’ heel of quantum computers: noise. The research by Gu, Retzker, and Kubica shows that by making qubits a bit smarter about their own errors, we can significantly lower the overhead on the road…

Microsoft’s Majorana-Based Quantum Chip – Beyond the Hype
In February 2025, Microsoft unveiled “Majorana 1,” an eight-qubit quantum chip built on a topological qubit architecture – a first-of-its-kind design leveraging exotic Majorana quasiparticles. This chip uses a new material called a “topoconductor” (a specially engineered topological superconductor) made from indium arsenide and aluminum, which can host and control Majorana zero modes (MZMs) to serve as qubits. Microsoft’s announcement…

First Successful Factorization of RSA-2048 by Quantum Computer? Not Even Close!
Chinese researchers published “A First Successful Factorization of RSA-2048 Integer by D-Wave Quantum Computer.” To get straight to the point - the title is misleading. The authors did NOT factor a general RSA-2048 key (as used in real cryptography); instead, they factored a specially structured 2048-bit semiprime chosen to be extremely easy.

RSA-2048 Within Reach of 1730 Qubits. Or is it?
The paper’s main claim is striking: by using approximate residue arithmetic and other optimizations, one can factor an RSA-2048 number with around 1730 logical qubits – dramatically down from the ~4000–6000 logical qubits required by earlier methods. (See one of my recent posts "4,099 Qubits: The Myth and Reality of Breaking RSA-2048 with Quantum Computers" for more info on how…
