Hilbert space signatures of non-ergodic glassy dynamics
Aleksey Lunkin, Nicole S. Ticea, Shashwat Kumar +292
Disorder in quantum many-body systems can drive transitions between ergodic and non-ergodic phases, yet the nature--and even the existence--of these transitions remains intensely d…
Constructive interference at the edge of quantum ergodic dynamics
Dmitry A. Abanin, Rajeev Acharya, Laleh Aghababaie-Beni +262
Quantum observables in the form of few-point correlators are the key to characterizing the dynamics of quantum many-body systems. In dynamics with fast entanglement generation, qua…
Viewing protected superconducting qubits through the lens of the cat qubit
Simon Lieu, Emma L. Rosenfeld, Kyungjoo Noh +1
We draw analogies between protected superconducting qubits and bosonic qubits by studying the fluxonium Hamiltonian in its Fock basis. The mean-field phase diagram of fluxonium (at…
Impact of Josephson junction array modes on fluxonium readout
Shraddha Singh, Gil Refael, Aashish Clerk +1
Dispersive readout of superconducting qubits is often limited by readout-drive-induced transitions between qubit levels. While there is a growing understanding of such effects in t…
