Exponentially robust non-Clifford gate in a driven-dissipative circuit
Liam O'Brien, Gil Refael, Frederik Nathan
Recent work (Nathan et al, arXiv:2405.05671) proposed an architecture for a dissipatively stabilized GKP qubit, and protocols for protected Clifford gates. Here we propose a protoc…

Self-correcting GKP qubit and gates in a driven-dissipative circuit
Frederik Nathan, Liam O'Brien, Kyungjoo Noh +4
We show that a self-correcting GKP qubit can be realized with a high-impedance LC circuit coupled to a resistor and a Josephson junction via a controllable switch. When activating…
