Tantalum Damascene Coplanar Waveguide Resonators Fabricated Using 300 mm Scale Processes
Ekta Bhatia, Yingge Du, Krishna P Koirala +12
Surface oxides contribute to losses in superconducting transmon devices resulting in degraded performance. We explore the use of the damascene process to replace the sidewall nativ…
Readout-induced suppression and enhancement of superconducting qubit lifetimes
Ted Thorbeck, Zhihao Xiao, Archana Kamal +1
It has long been known that the lifetimes of superconducting qubits suffer during readout, increasing readout errors. We show that this degradation is due to the anti-Zeno effect,…
Strong parametric dispersive shifts in a statically decoupled multi-qubit cavity QED system
T. Noh, Z. Xiao, K. Cicak +8
Cavity quantum electrodynamics (QED) with in-situ tunable interactions is important for developing novel systems for quantum simulation and computing. The ability to tune the dispe…
Perturbative diagonalization for time-dependent strong interactions
Z. Xiao, E. Doucet, T. Noh +4
We present a systematic method to implement a perturbative Hamiltonian diagonalization based on the time-dependent Schrieffer-Wolff transformation. Applying our method to strong pa…
Strong coupling diagnostics for multi-mode open systems
C. Kow, Z. Xiao, A. Metelmann +1
We present a new method to diagnose strong coupling in multi-mode open systems. Our method presents a non-trivial extension of exceptional point (EP) analysis employed for such sys…
An analytically simple and computationally efficient Gaussian beam mode-decomposition approach to classical diffraction theory
Zhihao Xiao, R. Nicholas Lanning, Mi Zhang +3
We present a method of Gaussian-beam-mode decomposition to calculate classical diffraction of optical beams by apertures. This method offers a entirely different approach to examin…
