Qubit decoherence due to detector switching
I. Serban, F. K. Wilhelm
We provide insight into the qubit measurement process involving a switching type of detector. We study the switching-induced decoherence during escape events. We present a simple m…
Quantum nondemolition-like, fast measurement scheme for a superconducting qubit
I. Serban, B. L. T. Plourde, F. K. Wilhelm
We present a measurement protocol for a flux qubit coupled to a dc-Superconducting QUantum Interference Device (SQUID), representative of any two-state system with a controllable c…
Phase-space theory for dispersive detectors of superconducting qubits
I. Serban, E. Solano, F. K. Wilhelm
Motivated by recent experiments, we study the dynamics of a qubit quadratically coupled to its detector, a damped harmonic oscillator. We use a complex-environment approach, explic…
Crossover from weak to strong coupling regime in dispersive circuit QED
I. Serban, E. Solano, F. K. Wilhelm
We study the decoherence of a superconducting qubit due to the dispersive coupling to a damped harmonic oscillator. We go beyond the weak qubit-oscillator coupling, which we associ…
