Decoherence of coherent electronic excited state in the reaction center of the photosynthetic purple bacterium Rhodobacter sphaeroides
Xian-Ting Liang, Wei-Min Zhang, Yi-Zhong Zhuo
In this paper, we present a theoretical description to the quantum coherence and decoherence phenomena of energy transfer in photosynthesis observed in a recent experiment [see Sci…
Study of the decoherence of a double quantum dot charge qubit via the Redfield equation
Zeng-Zhao Li, Xiao-Yin Pan, Xian-Ting Liang
By using the Redfield form of the master equation, we investigate the decoherence times of a double quantum dot charge qubit (DQDCQ) in three different cases, namely when it is cou…
Decoherence and purity of a driven solid-state qubit in Ohmic bath
Zhi-Qiang Li, Xian-Ting Liang
In this paper we study the decoherence and purity of a driven solid-state qubit in the Ohmic bath by using the method based on the master equation. At first, instead of solving the…
Decoherence and relaxation of qubits coupled to low- and medium-frequency Ohmic baths directly and via a harmonic oscillator
Xian-Ting Liang
Using the numerical path integral method we investigate the decoherence and relaxation of qubits in spin-boson (SB) and spin-intermediate harmonic oscillator (IHO)-bath (SIB) model…
