Entanglement entropy of particles in a perturbative scattering
Jinbo Fan, Xuanting Ji, Xi-Jun Ren
The entanglement among scattering particles in an exemplary quantum electrodynamics (QED) process is studied perturbatively. To increase the computational accuracy, we need to cons…
Entanglement entropy and monotones in scattering process
Jinbo Fan, Gao-Ming Deng, Xi-Jun Ren
In this paper, we study the entanglement property of a 4-particle system. In this system, two initially entangled electrons A and C are scattered by two uncorrelated positrons B an…
Quantum discord: "discord" between the whole and its constituent
X. -J. Ren, H. Fan
Quantum discord, a measure of quantum correlation beyond entanglement, is initially defined as the discord between two classically equivalent while quantum discordant definitions o…
Non-monogamy of quantum discord and upper bounds for quantum correlation
Xi-Jun Ren, Heng Fan
We consider a monogamy inequality of quantum discord in a pure tripartite state and show that it is equivalent to an inequality between quantum mutual information and entanglement…
Unified Universal Quantum Cloning Machine and Fidelities
Yi-Nan Wang, Han-Duo Shi, Zhao-Xi Xiong +4
We present a unified universal quantum cloning machine, which combines several different existing universal cloning machines together including the asymmetric case. In this unified…
Permutation-invariant monotones for multipartite entanglement characterization
Xi-Jun Ren, Wei Jiang, Xingxiang Zhou +2
In this work we consider the permutational properties of multipartite entanglement monotones. Based on the fact that genuine multipartite entanglement is a property of the entire m…
