Incompatibility of Observables as State-Independent Bound of Uncertainty Relations
Yunlong Xiao, Cheng Guo, Fei Meng +2
For a pair of observables, they are called "incompatible", if and only if the commutator between them does not vanish, which represents one of the key features in quantum mechanics…

Obtain -state from three-qubit -state on rate 1
Nengkun Yu, Cheng Guo, Runyao Duan
In this paper, we study the entanglement transformation rate between multipartite states under stochastic local operations and classical communication (SLOCC). Firstly, we show tha…
