Non-perturbative switching rates in bistable open quantum systems: from driven Kerr oscillators to dissipative cat qubits
Léon Carde, Ronan Gautier, Nicolas Didier +3
In this work, we use path integral techniques to predict the switching rate in a single-mode bistable open quantum system. While analytical expressions are well-known to be accessi…

Flux-pump induced degradation of for dissipative cat qubits
Léon Carde, Pierre Rouchon, Joachim Cohen +1
Dissipative stabilization of cat qubits autonomously corrects for bit flip errors by ensuring that reservoir-engineered two-photon losses dominate over other mechanisms inducing ph…

Noise Mitigation in Single Microwave Photon Counting by Cascaded Quantum Measurements
Alexandre S. May, Leo Sutevski, Jeanne Solard +7
While single-photon counting is routinely achieved in the optical domain, operational single microwave photon detectors (SMPDs) have only recently been demonstrated. SMPDs are crit…
