State-independent uncertainty relations on multipartite spin -systems
Yiling Wang, Kailash Misra, Naihuan Jing
The paper introduces a representation‑theoretic method to derive exact state‑independent variance‑based uncertainty bounds for multipartite spin‑½ (qubit) systems, providing analyt…
Unified monogamy and polygamy relations for multipartite systems
Yue Cao, Naihuan Jing, Kailash Misra +1
The paper introduces a tunable, parameter‑dependent framework that unifies and refines monogamy and polygamy inequalities for multipartite entanglement measures, providing tighter…
Zassenhaus Expansion in Solving the Schrödinger Equation
Yali Du, Molena Nguyen, Naihuan Jing +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-po…
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.…
