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…
