Crossover of phase qubit dynamics in the presence of a negative-result weak measurement
Crossover of phase qubit dynamics in the presence of a negative-result weak measurement
Coherent dynamics of a superconducting phase qubit is considered in the presence of both unitary evolution due to microwave driving and continuous non-unitary collapse due to negative-result measurement. In the case of a relatively weak driving, the qubit dynamics is dominated by the non-unitary evolution, and the qubit state tends …
