Lescanne helped demonstrate cat-qubit protection against bit flips and cofounded Alice & Bob to develop superconducting hardware that uses this asymmetry between error types.
Alice & BobarXiv / Nature PhysicsLescanne’s research explores whether hardware can suppress one class of errors before a larger correction code is applied. His collaborative cat-qubit experiment encoded information in a superconducting resonator stabilized by two-photon dissipation. Increasing the separation of its states suppressed bit flips, while phase flips still required attention. Alice & Bob’s history links that work to its 2020 founding. His contribution thus spans an experimentally tested protection mechanism and the attempt to develop it into a computing architecture.

Work, in context- 2020
Measuring exponential bit-flip suppression
Lescanne was first author of an experiment encoding a qubit in a superconducting resonator with two-photon dissipation. Separating the encoded states reduced bit flips exponentially while increasing phase flips only linearly, establishing a deliberately biased noise model.
First author of the cat-qubit experiment; the measured behavior is a collaborative result.

Cofounding Alice & Bob
Alice & Bob’s institutional history records its founding by Lescanne and Théau Peronnin in 2020, following their cat-qubit research. As CTO, Lescanne works on translating that experimental approach into a superconducting computing platform.
Cofounder with Théau Peronnin and current CTO; this documents entrepreneurship and technical responsibility, not a completed architecture.

Keep in perspective
Cat-qubit bit-flip protection is not represented as correction of every error or proof of a completed fault-tolerant computer.
