With its unique band structure endowing it with wideband absorption and exceptionally low heat capacity, graphene is an ideal candidate for the study of single photon detection from the near-infrared regime all the way to the microwave regime. Here we present 1) modeled results demonstrating the promise of the graphene-based Josephon junction (GJJ) as a wideband single photon detector, 2)...
Fluxonium is a multi-level superconducting artificial atom. Its rich spectrum and selection rules provide promising solutions to standing problems in quantum computing such as low coherence and spectral crowding. In this talk, we describe our progress towards constructing a quantum processor based on fluxonium qubits. More specifically, our current focus is to experimentally realize a...
Nonequilibrium quasiparticle excitations (QPs) are known to be a significant source of dissipation in superconducting quantum devices, though their observed density at 20 mK remains a mystery. In this talk, I will discuss our recent work utilizing offset-charge-sensitive transmons to probe QP dynamics. We detect QP tunneling events by coherent mapping of charge parity onto the qubit state and...
