Sharp State-Independent Uncertainty Relations for Multipartite systems
Yiling Wang, Naihuan Jing
Uncertainty relations constrain the fluctuations of incompatible observables, but most familiar bounds depend on the quantum state. State-independent uncertainty relations instead…
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 …
Zassenhaus Expansion in Solving the Schrödinger Equation
Yali Du, Naihuan Jing, Molena Nguyen +1
A fundamental challenge in quantum simulation is approximating the time-evolution operator \(U(t)=e^{-i\mathcal{H}t}\) generated by a large sum of typically non-commuting Hamiltoni…
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 bounds for generalized monogamy and polygamy relations
Yue Cao, Naihuan Jing, Yiling Wang
We study generalized monogamy and polygamy relations for concurrence of assistance and negativity of assistance using parametrized bounds in general multi-partite quantum systems.…
