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…
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…
Topological frequency conversion in rhombohedral multilayer graphene
Ãtienne Lantagne-Hurtubise, Iliya Esin, Gil Refael +1
We show that rhombohedral multilayer graphene supports topological frequency conversion, whereby a fraction of electrons transfer energy between two monochromatic light sources at…
Evidence of Floquet electronic steady states in graphene under continuous-wave mid-infrared irradiation
Yijing Liu, Christopher Yang, Gabriel Gaertner +9
Light-induced phenomena in materials can exhibit exotic behavior that extends beyond equilibrium properties, offering new avenues for understanding and controlling electronic phase…
