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 […]

Performance of Superconducting Resonators Suspended on SiN Membranes

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Trevor Chistolini, Kyunghoon Lee, Archan Banerjee, Mohammed Alghadeer, Christian Jünger | Summary: Suspending devices on thin SiN membranes can limit their interaction with the bulk substrate and reduce parasitic capacitance to ground. While suspending devices on membranes is used in many fields including radiation detection using superconducting […]

Universal non-Hermitian flow in one-dimensional PT-symmetric quantum criticalities

Kavli Affiliate: Ke Wang | First 5 Authors: Xin-Chi Zhou, Ke Wang, , , | Summary: The critical point of a topological phase transition is described by a conformal field theory (CFT), where the finite-size corrections to the ground state energy are uniquely related to its central charge. We study the finite-size scaling of the […]
