Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Equivalence Checking of Quantum Circuits by Nonlocality
量子电路 非局域 等价性检验
2023/4/17
Suppose two quantum circuit chips are located at different places, for which we do not have any prior knowledge, and cannot see the internal structures either. In such a situation, a realistic and fun...
Experimental distillation of quantum nonlocality
Experimental distillation uantum nonlocality
2016/1/23
We report the first experimental demonstration of distillation of quantum nonlocality, confirming the recent theoretical protocol [Phys. Rev. Lett. 102, 120401 (2009)]. Quantum nonlocality is describe...
Solution of the Schrodinger equation containing a Perey-Buck nonlocality
Solution of the Schrodinger equation Perey-Buck nonlocality Computational Physics
2012/4/19
The solution of a radial Schr\"odinger equation for {\psi}(r) containing a nonlocal potential of the form \int{K(r,r') {\psi}(r') dr'} is obtained to high accuracy by means of two methods. An applicat...
Two-vortex structure of electron, nonlocality and Dirac equation
Two-vortex structure electron nonlocality Dirac equation
2011/8/11
Abstract: The dimensionless electromagnetic coupling constant $\alpha=e^2 /\hbar c$ may have three interpretations: as the well known ratio between the electron charge radius $e^2/mc^2$ and the Compto...
The Dynamical Nonlocality of Neutral Kaons and the Kaonic Quantum Eraser
Bell inequality quantum marking and erasure neutral kaons
2010/11/8
Testing quantum foundations for systems in high energy physics gets currently more and more attention e.g. witnessed for entangled neutral K-mesons by the approved programme of the KLOE collaboration ...
Specker's Parable of the Over-protective Seer: Implications for Contextuality, Nonlocality and Complementarity
Specker's Parable the Over-protective Seer Implications for Contextuality Nonlocality Complementarity
2010/10/29
We revisit an example of stronger-than-quantum correlations that was discovered by Ernst Specker in 1960. It is found to provide a narrative thread that weaves together a large number of foundational...
The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in the foundations of qua...
Optimal Protocols for Nonlocality Distillation
Nonlocality Nonlocal Boxes NLBs Distillation Quantum Information
2010/10/19
Forster, Winkler, and Wolf recently showed that weak nonlocality can be amplified by giving the
first protocol that distills a class of nonlocal boxes (NLBs) [Phys. Rev. Lett. 102, 120401 (2009)].We ...
Deriving Bell's nonlocality from nonlocality at detection
Deriving Bell nonlocality nonlocality detection
2010/10/18
It is argued that Bell’s nonlocality is a particular case of nonlocality at detection, which appears already in single-particle interference experiments. The unity of nonlocality and local causality i...
Testing nonlocality over 12.4 km of underground fiber with universal time-bin qubit analyzers
Testing nonlocality time-bin qubit analyzers
2010/3/10
We experimentally demonstrate that the nonlocal nature of time-bin entangled photonic qubits persists when one or two qubits of the pair are converted to polarization qubits. This is possible by imple...
Svetlichny's inequality and genuine tripartite nonlocality in three-qubit pure states
Svetlichny's inequality genuine tripartite nonlocality three-qubit pure states
2010/4/7
The violation of the Svetlichny's inequality (SI) [Phys. Rev. D, 35, 3066 (1987)] is sufficient but not necessary for genuine tripartite nonlocal correlations. Here we quantify the relationship betwee...
Quantum Mechanics and Nonlocality: In Search of Instructive Description
Quantum Mechanics Nonlocality Instructive Description
2010/4/12
A problem with an instructive description of measurement process for sufficiently separated entangled quantum systems is well known. More precise and crafty experiments together with new technological...
Classification and quantification of nonlocality in ensembles consisting of orthogonal bipartite states
Classification quantification ensembles consisting orthogonal bipartite states
2010/4/8
An ensemble of mutually orthogonal multipartite states may not be distinguishable by means of local operations and classical communication (LOCC) and could exhibit a kind of nonlocality different from...
Classical Interaction Cannot Replace Quantum Nonlocality
Classical Interaction Quantum Nonlocality
2010/4/8
We present a two-player communication task that can be solved by a protocol of polylogarithmic cost in the simultaneous message passing model with classical communication and shared entanglement, but ...
Entanglement and nonlocality of a single relativistic particle
Entanglement nonlocality relativistic particle
2010/4/8
Recent work has argued that the concepts of entanglement and nonlocality must be taken seriously even in systems consisting of only a single particle. These treatments, however, are nonrelativistic an...
