Microsoft captured quantum news headlines on February 19, 2025 by publishing an arXiv blueprint for its future fault-tolerant quantum computers (FTQCs) using Majorana fermions, a Nature paper about the measurement of Majorana Zero Modes (MZMs) in a chip containing the equivalent of half a physical topological qubit, and then a press release summarizing the whole and introducing […]

Welcome to the 79th episode of “Decode Quantum”. We continue our “international episodes”, this times with the cofounders of the US startup EeroQ, Nick Farina and Johannes Pollanen, which aims to create qubits with electron spins, electrons being shielded from controlling electronic circuits by a layer of superfluid helium. This is the only company doing […]

On December 9th 2024, Google made the news with announcing its 105-qubit superconducting Willow chip, with some more details here. It was linked to the release of a new Nature paper on this chip and extravagant claims about this quantum computer’s ability to solve some specific problem in a couple minutes, that would take 10^25 years […]

I published the open-source book “Understanding Quantum Technologies 2024” late September 2024. Since then, I have updated it many times to follow the news, add a couple companies and also correct various spelling, presentation and other errors. I try to keep up with the scientific and other news until I publish this edition on arXiv […]
