How to compare logical qubits?

One 2026 quantum prediction is that it will to be the year when useful logical qubit based quantum computers will appear (dealt with prudently by Riverlane and Innovation Origins). In a sense, it would mark an irreversible transition from NISQ to FTQC. Here, vendors face a complexity challenge not only to deliver what’s in their roadmaps […]

Sorting out the confusion on quantum computing utility

Understanding quantum computing’s pace of progress is not an easy task. Recent months have complicated it with contradictory messages. CEOs like Jensen Huang (Nvidia) and Mark Zuckerberg (Meta) estimated that useful quantum computers were decades away, while others like Satya Nadella (Microsoft) and Sundar Pichai (Google) cast it as being just years from now. Some […]

Inside Microsoft Majorana-1

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 […]

Decode Quantum avec Valentin Savin du CEA-Leti

Dans le 70e épisode des entretiens Decode Quantum, Fanny Bouton et moi-même sommes avec Valentin Savin du CEA-Leti, pour parler du sujet de la correction d’erreurs. Cet entretien est aussi diffusé par Frenchweb. Valentin Savin a un master en mathématiques de l’ENS Lyon et de l’Université Joseph Fourier de Grenoble, puis a réalisé une thèse […]

Decode Quantum with Jay Gambetta from IBM

In our third Decode Quantum episode in English after Simone Severini from AWS and Tommaso Calarco from Julich, we are with Jay Gambetta from IBM. And he welcomed us since we recorded this episode near his office at IBM Yorktown Heights Research lab in New York state. This is the 68th episode of Decode Quantum. […]
