Prediction of short time qubit readout via measurement of the next quantum jump of a coupled damped driven harmonic oscillator
arXiv:2006.11950 · doi:10.1103/PhysRevLett.125.260403
Abstract
The dynamics of the next quantum jump for a qubit [two level system] coupled to a readout resonator [damped driven harmonic oscillator] is calculated. A quantum mechanical treatment of readout resonator reveals non exponential short time behavior which could facilitate detection of the state of the qubit faster than the resonator lifetime.
