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…
Reduced dynamics with renormalization in solid-state charge qubit measurement
JunYan Luo, Hujun Jiao, Feng Li +2
Quantum measurement will inevitably cause backaction on the measured system, resulting in the well known dephasing and relaxation. In this report, in the context of solid--state qu…
Coulomb blockade double-dot Aharonov-Bohm interferometer: harmonic decomposition of the interference pattern
Feng Li, HuJun Jiao, Hui Wang +2
For the solid state double-dot interferometer, the phase shifted interference pattern induced by the interplay of inter-dot Coulomb correlation and multiple reflections is analyzed…
Coulomb blockade double-dot Aharonov-Bohm interferometer: giant fluctuations
Feng Li, HuJun Jiao, JuYan Luo +2
Electron transport through two parallel quantum dots is a kind of solid-state realization of double-path interference. We demonstrate that the inter-dot Coulomb correlation and qua…
Weak Measurement of Qubit Oscillations with Strong Response Detectors: Violation of the Fundamental Bound Imposed on Linear Detectors
HuJun Jiao, Shi-Kuan Wang, Feng Li +1
We investigate the continuous weak measurement of a solid-state qubit by single electron transistors in nonlinear response regime. It is found that the signal-to-noise ratio can vi…
Magnetic field switching in parallel quantum dots
Feng Li, Xin-Qi Li, Wei-Min Zhang +1
We show that the Coulomb blockade in parallel dots pierced by magnetic flux completely blocks the resonant current for any value of except for integer multiples of the flux…
