Charge Parity Rates in Transmon Qubits with Different Shunting Capacitors
Yi-Hsiang Huang, Haozhi Wang, Yizhou Huang +3
The presence of non-equilibrium quasiparticles in superconducting resonators and qubits operating at millikelvin temperature has been known for decades. One metric for the number o…

Generalized geometric speed limits for quantum observables
Jacob Bringewatt, Zach Steffen, Martin A. Ritter +6
Leveraging quantum information geometry, we derive generalized quantum speed limits on the rate of change of the expectation values of observables. These bounds subsume and, for Hi…
