State-independent uncertainty relations on multipartite spin -systems
Yiling Wang, Kailash Misra, Naihuan Jing
Uncertainty relations quantify fundamental limits on simultaneous measurement of quantum observables. While conventional formulations are state-dependent, state-independent uncerta…
Unified monogamy and polygamy relations for multipartite systems
Yue Cao, Naihuan Jing, Kailash Misra +1
For a bipartite entanglement measure that satisfies the th-power monogamy inequality (Eq.~\eqref{e:chap1-ineq1}), and for its assisted counterpart …
Superior monogamy and polygamy relations and estimates of concurrence
Yue Cao, Naihuan Jing, Kailash Misra +1
It is well known that any well-defined bipartite entanglement measure obeys th-monogamy relations Eq. (1.1) and assisted measure obeys th-poly…
Tighter parameterized monogamy relations
Yue Cao, Naihuan Jing, Kailash Misra +1
We seek a systematic tightening method to represent the monogamy relation for some measure in multipartite quantum systems. By introducing a family of parametrized bounds, we obtai…
