Silicon Runs Its First Real Algorithm: Grover’s Search on Four Qubits With Every Gate Above Threshold
24 Feb 2025 - There is a difference between proving you can throw a ball and proving you can play a game. For three years, silicon spin qubits have been proving they can throw: individual gate operations above the fault-tolerance threshold, entanglement between pairs and triplets of qubits, the steady accumulation of quality metrics that justify the platform's ambitions. But…

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…
