A gate-tunable, field-compatible fluxonium
Marta Pita-Vidal, Arno Bargerbos, Chung-Kai Yang +7
Circuit quantum electrodynamics, where photons are coherently coupled to artificial atoms built with superconducting circuits, has enabled the investigation and control of macrosco…

Superconducting circuit protected by two-Cooper-pair tunneling
W. C. Smith, A. Kou, X. Xiao +2
We present a protected superconducting qubit based on an effective circuit element that only allows pairs of Cooper pairs to tunnel. These dynamics give rise to a nearly degenerate…

Gated conditional displacement readout of superconducting qubits
S. Touzard, A. Kou, N. E. Frattini +6
We have realized a new interaction between superconducting qubits and a readout cavity that results in the displacement of a coherent state in the cavity, conditioned on the state…
