Predicting Quantum Computing Winning 2025 Nobel Physics Prize
Announcements of 2025 Nobel Prize winners start tomorrow. With announcements for Nobel Prize for Physics scheduled for Tuesday 7 October. Every autumn I indulge in a guilty pleasure: browsing speculative lists of Nobel Prize contenders and trying to guess who might pick up the world’s most coveted science prize. Part of the fun is that the Nobel process is shrouded in secrecy. According to the…

Quantum MedBeds and Death Threats
I never write about current politics. This might be my first on this blog. In fact, for the sake of my own sanity, I’ve made a point of steering this blog and most of my day clear of politics and the daily chaos of partisan news. I prefer to focus on science and quantum tech. However, recent events have dragged me out of that apolitical…

Cisco’s Full-Stack Approach and the Road to Quantum Data Centers
Cisco took on an ambitious full-stack strategy to make distributed quantum computing a reality sooner than many expect. Instead of waiting for a single perfect quantum processor with millions of qubits, Cisco is building the hardware, software, and architecture needed to network today’s smaller quantum machines into unified quantum data centers. This approach mirrors how classical computing scaled - connecting many modest nodes to achieve…

Factoring RSA-2048 in 20 Minutes with 42 Qubits
We present a resource estimate for factoring 2048-bit RSA integers using a quantum computer with just 42 physical qubits and a runtime of approximately 20 minutes. Our approach combines well-established results from the recent literature: Regev's O(n3/2) quantum factoring algorithm [1], asymptotically optimal qLDPC codes at their proven constant encoding rate [2], magic state cultivation at projected efficiency [3], demonstrated multi-hour coherence times in rare-earth…

The Easiest Job in Quantum Computing – Being a Cynic
Don’t mistake the noise of cynicism for the signal of intelligence. If someone validates themselves as a useless cynic - unwilling to provide anything beyond scoffs and derision - don’t waste your energy getting dragged into their performative pessimism. Instead, direct your attention to the genuine skeptics and curious contrarians who challenge ideas in good faith. Engage with those asking hard questions and with the enthusiasts…

Why Companies May Need a Chief Quantum Officer (CQO)
In my opinion, forward-thinking organizations should consider creating a Chief Quantum Officer (CQO) role. Much like those historical electricity executives, a CQO would spearhead the adoption of a disruptive technology that is revolutionary, promising - but widely misunderstood. It’s a provocative idea (even “a job title from Star Trek,” as one commentator quipped ), but it’s quickly moving from speculation to reality. A few bold…

Magic States: A Key to Universal Fault-Tolerant Quantum Computing
Magic states are special quantum states that enable the universal operations needed for any quantum algorithm, yet which are not themselves easy to produce or protect. In essence, magic states supply the "extra quantum sauce" that elevates a protected quantum computer from what could be emulated on a classical computer to a machine that can outperform classical supercomputers. Recent breakthroughs - from theory and small-scale…

The Nervous System of Quantum Computing: A Deep Dive into Quantum Control Systems
In July 2025, Keysight Technologies shipped a piece of equipment to a research institute in Tsukuba, Japan, that most people outside the quantum industry had never heard of - yet without it, the 1,000-qubit quantum computer it was destined for would have been little more than an extraordinarily expensive refrigerator. The device was a quantum control system: a dense rack of electronics designed to translate…
