From January 20th to 23rd 2025, I participated in the QT4HEP conference at CERN and had a chance to visit several experiments from CERN. This was quite an experience that I recount here. This illustrated post contains: A description of QT4HEP’s conference highlights. A primer on high-energy particle physics. An overview or CERN activities. A […]

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 […]

Bienvenue dans ce 65e épisode de Quantum, le podcast de l’actualité quantique. Nous avions initialement prévu de faire relâche en fin d’année et de reprendre le volant début février mais l’actualité nous a rattrapés. L’annonce récente de Google avec sa puce Willow a défrayé la chronique et surtout m’a bien titillé. Il se trouve que […]

Welcome to the 78th episode of Decode Quantum, where we continue to travel around the world. We are now in the UK with Sebastian Weidt, the founder and CEO of Universal Quantum, a startup creating scalable trapped-ions quantum computers. Sebastian Weidt is the CEO and co-founder of Universal Quantum since 2019, when the company was […]

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 […]

Welcome to the 77th episode of “Decode Quantum”. We continue our “international episodes”, this times with the cofounders of the US startup SEEQC, John Levy (CEO) and Oleg Mukhanov (CTO), who are creating superconducting control electronic circuits for solid state qubits. They are the only company in that field. We had a chance to meet […]

J’assistais le 7 novembre 2024 au ministère de la recherche et de l’enseignement supérieur à Paris à un séminaire de présentation du programme de “recherche à risque” lancé par l’État fin 2023. J’y étais invité en tant que membre du comité d’experts de sélection des projets à risque du Programme Inria Quadrant (PIQ), Inria étant […]

I published the 2024 and 7th edition of the book “Understanding Quantum Technologies” back in September 26th. Since then, I have continuously updated and refined it, embedding the continuous flow of scientific and industry news in the quantum space, and also corrected some errors found by various readers. I also identified a couple new quantum […]

Nous voici dans le 63 ième épisode de Quantum, le podcast francophone de l’actualité quantique qui persiste et perdure maintenant depuis plus de 5 ans. Au menu de cet épisode : de nombreux voyages (Grenoble, Munich, New York). Des nouveautés chez Quobly, Quandela, IBM, QuEra, des prix Nobel de physique et de chimie à la sauce […]

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 […]

Welcome to the 76th episode of Decode Quantum. In our series of three episodes recorded in Lindau where dozens of physics Nobel laureates met with young scientists, we picked a few of them who are specialized in the broad field of quantum computing to head their thoughts about it: Caroline Tornow (ETH Zurich), Francesca Pietracaprina […]
