Large-deviation analysis for counting statistics in mesoscopic transports
Jun Li, Yu Liu, Jing Ping +3
We present an efficient approach, based on a number-conditioned master equation, for large-deviation analysis in mesoscopic transports. Beyond the conventional full-counting-statis…
Undetectable quantum transfer through a continuum
Jing Ping, Yin Ye, Xin-Qi Li +2
We demonstrate that a quantum particle, initially prepared in a quantum well, can propagate through a reservoir with a continuous spectrum and reappear in a distant well without be…
Quantum coherence and entanglement induced by the continuum between distant localized states
Jing Ping, Xin-Qi Li, Shmuel Gurvitz
It is demonstrated that two distant quantum wells separated by a reservoir with a continuous spectrum can possess bound eigenstates embedded in the continuum. These represent a lin…
Quantum Efficiency of Charge Qubit Measurements Using a Single Electron Transistor
Yin Ye, Jing Ping, HuJun Jiao +2
The quantum efficiency, which characterizes the quality of information gain against information loss, is an important figure of merit for any realistic quantum detectors in the gra…
