A Robust Quantum Random Access Memory
Fang-Yu Hong, Yang Xiang, Zhi-Yan Zhu +2
A "bucket brigade" architecture for a quantum random memory of memory cells needs times of quantum manipulation on control circuit nodes per memory call. Here we…
Joint measurements and Svetlichny's inequality
Yang Xiang, Wei Ren
We prove that the Svetlichny's inequality can be derived from the existence of joint measurements and the principle of no-signaling. Then we show that, on the basis of quantum meas…
Investigation of nonlocal information as condition for violations of Bell inequality and information causality
Yang Xiang, Shi-Jie Xiong
On the basis of local realism theory, nonlocal information is necessary for violation of Bell's inequality. From a theoretical point of view, nonlocal information is essentially th…
Local vertical measurements and violation of Bell inequality
Yang Xiang, Shi-Jie Xiong
For two qubits belonging to Alice and Bob, we derive an approach to setup the bound of Bell operator in the condition that Alice and Bob continue to perform local vertical measurem…
Comment on ``Geometric phase of entangled spin pairs in a magnetic field''
Yang Xiang, Shi-Jie Xiong
The degree of entanglement between two spins may change due to interaction. About this we find that a wrong result in a recent work by Ge and Wadati [Phys. Rev. A {\bf72}, 052101(2…
Entropy exchange, coherent information and concurrence
Yang Xiang, Shi-Jie Xiong
For a simple model we derive analytic expressions of entropy exchange and coherent information, from which relations between them and the concurrence are drawn. We find that in the…
