Operating in a deep underground facility improves the locking of gradiometric fluxonium qubits at the sweet spots
Daria Gusenkova, Francesco Valenti, Martin Spiecker +14
We demonstrate flux-bias locking and operation of a gradiometric fluxonium artificial atom using two symmetric granular aluminum (grAl) loops to implement the superinductor. The gr…
Lifetime renormalization of driven weakly anharmonic superconducting qubits: II. The readout problem
Alexandru Petrescu, Moein Malekakhlagh, Hakan E. Türeci
Recent experiments in superconducting qubit systems have shown an unexpectedly strong dependence of the qubit relaxation rate on the readout drive power. This phenomenon limits the…
Lifetime renormalization of weakly anharmonic superconducting qubits: I. Role of number non-conserving terms
Moein Malekakhlagh, Alexandru Petrescu, Hakan E. Türeci
The dynamics of a weakly anharmonic superconducting qubit in a complex electromagnetic environment is generally well-described by an effective multimode Kerr Hamiltonian at suffici…
