Voltage-controlled entanglement and quantum-information transfer between spatially separated quantum-dot molecules
Xin‐You Lü, Jing Wu, Lili Zheng, Zhiming Zhan · Physical Review A · 2011
We propose two schemes for generating entanglement and quantum-state transfer (QST) between two spatially separated semiconductor quantum dot molecules (QDMs) based on voltage-controlled tunneling effects. In the present schemes, two QDMs are trapped in two spatially separated cavities connected by a fiber. By numerically simulating the evolution of the system, we show that the generation of entanglement and QST can be controlled by an external gate voltage in our schemes. Moreover, proposed schemes are robust against the noise of system parameters.
