Space-time uncertainty relation from quantum and gravitational principles
Yi-Xin Chen, Yong Xiao
By collecting both quantum and gravitational principles, a space-time uncertainty relation is derived. It can be used to facilitate the discu…
Entanglement of formation from optimal decomposition
Lin Chen, Yi-Xin Chen
We present a new method of analytically deriving the entanglement of formation of the bipartite mixed state. The method realizes the optimal decomposition families of states. Our m…
Multiqubit entanglement witness
Lin Chen, Yi-Xin Chen
We introduce a feasible method of constructing the entanglement witness that detects the genuine entanglement of a given pure multiqubit state. We illustrate our method in the scen…
The Entropy Bound for Local Quantum Field Theory
Yi-Xin Chen, Yong Xiao
We investigate the entropy bound for local quantum field theory in this paper. Both the bosonic and fermionic fields confined to an asymptotically flat spacetime are examined. By i…
