Performance of Superconducting Resonators Suspended on SiN Membranes

Kavli Affiliate: Feng Wang | First 5 Authors: Trevor Chistolini, Kyunghoon Lee, Archan Banerjee, Mohammed Alghadeer, Christian Jünger | Summary: Correlated errors in superconducting circuits due to nonequilibrium quasiparticles are a notable concern in efforts to achieve fault tolerant quantum computing. The propagation of quasiparticles causing these correlated errors can potentially be mediated by phonons […]

Dynamical Freezing in Exactly Solvable Models of Driven Chaotic Quantum Dots

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Haoyu Guo, Rohit Mukherjee, Debanjan Chowdhury, , | Summary: The late-time equilibrium behavior of generic interacting models is determined by the coupled hydrodynamic equations associated with the globally conserved quantities. In the presence of an external time-dependent drive, non-integrable systems typically thermalize to an effectively infinite-temperature state, […]
