چکیده
A set of multipartite orthogonal quantum states is strongly nonlocal if it locally irreducible for every bipartition the subsystems [S. Halder, M. Banik, S. Agrawal, and Bandyopadhyay, Phys. Rev. Lett. 122, 040403 (2019)]. Although this property has been shown in three-, four-, five-partite systems, existence sets $N$-partite systems remains unknown when $N\ensuremath{\ge}6$. In paper, we successfully show that a entangled exists ${({\mathbb{C}}^{d})}^{\ensuremath{\bigotimes}N}$ all $N\ensuremath{\ge}3$ $d\ensuremath{\ge}2$, which reveals strong nonlocality general systems. For $N=3$ or 4 $d\ensuremath{\ge}3$, present consisting genuinely states, smaller size than any known product set. Finally, connect with local hiding information as an application.

Strong connections between quantum encodings, nonlocality, and quantum cryptography
Encoding information in quantum systems can offer surprising advantages but at the same time there are limitations that arise from the fact that measuring an observable may disturb the state of the quantum system. In our work, we provide an in-depth analysis of a simple question: What happens when we perform two measurements sequentially on the same quantum system? This question touches upon so...
متن کاملBound on tri-partite Hardy's nonlocality respecting all bi-partite principles
Recently, Gallego et al. [Phys. Rev. Lett. 107, 210403 (2011)] proved that any future information principle aiming at distinguishing between quantum and postquantum correlation must be intrinsically multipartite in nature. We establish similar results by using the device-independent success probability of Hardy?s nonlocality argument for tripartite quantum systems. We construct an example of a ...
متن کاملGeneral Nonlocality in Quantum Fields
The natural recognition of quantum nonlocality follows from the fact that a quantum wave is spatially extended. The waves of fermions display nonlocality in low energy limit of quantum fields. In this ab initio paper we propose a complex-geometry model that reveals the affection of nonlocality on the interaction between material particles of spin-1/2. To make nonlocal properties appropriately i...
متن کاملQuantum Nonlocality and Inseparability
wK = 1. A necessary condition for separability is derived and is shown to be more sensitive than Bell’s inequality for detecting quantum inseparability. Moreover, collective tests of Bell’s inequality (namely, tests that involve several composite systems simultaneously) may sometimes lead to a violation of Bell’s inequality, even if the latter is satisfied when each composite system is tested s...
متن کاملGeneral Nonlocality in Quantum Field
As a sequent study following a previous paper, this paper is dedicated to constructing a theory to determine the nonlocal region of quantum field by geometrical method. The study shows that the theory may also be the candidate of the nonperturbative one. Many symmetric laws are not strictly respected in this theory. Concerning QED and QCD, it is found that while the strength of field ~ B and ~ ...
