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 in a superconducting circuit with an oscillating voltage bias
Max Geier, Frederik Nathan
We propose a simple circuit architecture for a dissipatively error corrected Gottesman-Kitaev-Preskill (GKP) qubit. The device consists of a electromagnetic resonator with impedanc…
