Exponential suppression of bit-flips in a qubit encoded in an oscillator
Raphaël Lescanne, Marius Villiers, Théau Peronnin +6
A quantum system interacts with its environment, if ever so slightly, no matter how much care is put into isolating it. As a consequence, quantum bits (qubits) undergo errors, putt…
Detecting itinerant microwave photons with engineered non-linear dissipation
Raphaël Lescanne, Samuel Deléglise, Emanuele Albertinale +6
Single photon detection is a key resource for sensing at the quantum limit and the enabling technology for measurement based quantum computing. Photon detection at optical frequenc…
Structural instability of driven Josephson circuits prevented by an inductive shunt
Lucas Verney, Raphaël Lescanne, Michel H. Devoret +2
Superconducting circuits are a versatile platform to implement a multitude of Hamiltonians which perform quantum computation, simulation and sensing tasks. A key ingredient for rea…
Observing the escape of a driven quantum Josephson circuit into unconfined states
Raphaël Lescanne, Lucas Verney, Quentin Ficheux +4
Josephson circuits have been ideal systems to study complex non-linear dynamics which can lead to chaotic behavior and instabilities. More recently, Josephson circuits in the quant…
