Noise assisted quantum coherence protection in hierarchical environment
Xinyu Zhao, Yong-hong Ma, Yan Xia
In this paper, we investigate coherence protection of a quantum system coupled to a hierarchical environment by utilizing noise. As an example, we solve the Jaynes-Cummings (J-C) m…
Measurement of tunnel coupling in a Si double quantum dot based on charge sensing
Xinyu Zhao, Xuedong Hu
In Si quantum dots, valley degree of freedom, in particular the generally small valley splitting and the dot-dependent valley-orbit phase, adds complexities to the low-energy elect…
