Stabilization of finite-energy grid states of a quantum harmonic oscillator by reservoir engineering with two dissipation channels
Rémi Robin, Pierre Rouchon, Lev-Arcady Sellem
We propose and analyze an experimentally accessible Lindblad master equation for a quantum harmonic oscillator, simplifying a previous proposal to alleviate implementation constrai…

Dissipative protection of a GKP qubit in a high-impedance superconducting circuit driven by a microwave frequency comb
Lev-Arcady Sellem, Alain Sarlette, Zaki Leghtas +3
We propose a novel approach to generate, protect and control GKP qubits. It employs a microwave frequency comb parametrically modulating a Josephson circuit to enforce a dissipativ…

Convergence of bipartite open quantum systems stabilized by reservoir engineering
Rémi Robin, Pierre Rouchon, Lev-Arcady Sellem
We study a generic family of Lindblad master equations modeling bipartite open quantum systems, where one tries to stabilize a quantum system by carefully designing its interaction…
