Dans ce 75ième épisode de Quantum, le podcast de l’actualité quantique, toujours avec Fanny Bouton, nous faisons le tour habituel de l’actualité scientifique, technologique, événementielle et people du quantique en France et dans le monde.
Et comme d’habitude, voici le transcript, les liens utiles et illustrations de cette actualité.
Evénements
Séminaire SFGP
Je participais le 5 novembre à un séminaire organisé par la Société Française du Génie des Procédés : Génie des procédés & Machines quantiques. C’était un événement intéressant permettant de confronter les besoins d’une industrie tournée autour de la chimie industrielle et des capacités des technologies quantiques.

The online PDF version of the 8th edition of the book “Understanding Quantum Technologies” is available since September 29th.
As I do every year, I continue to update the book, first to publish it on arXiv which I did late October. On top of many small updates, I added a small section on the “Making of” of this version of the book which is the first I did in LaTeX.
I then continued to refine it – and refinement is an endless task – to publish it on Amazon KDP using self-publishing. The most tedious part was to create the cover with the right spine size. I automatized it entirely with LaTeX, to fit Amazon’s constraints.

In November 2025, Quantinuum released its Helios QPU with 98 qubits. It also announced it was sold to Singapore as part of a partnership with A*Star and to be deployed there in 2026. Helios got less attention than the recent news coming from Google (Willow, Echoes) and Microsoft (Majorana 1) but it deserves it. It is one of the best QPUs ever produced so far in the NISQ regime. I will look here at its key disclosed technical characteristics. It’s a first for me given I’ve mostly always published such posts only on superconducting and Majorana qubits.
Helios is fairly well described technically in Helios: A 98-qubit trapped-ion quantum computer by Anthony Ransford, M.S. Allman et al, arXiv, November 2025 (25 pages). Most of the information below comes from this preprint paper.
