In an electrical signalling system the signals are arranged to be split up into signal groups, each of which contains a predetermined number of signal elements which are linearly independent with respect to each other at the transmitter, corresponding signal elements in successive groups being related...
Diffusion noise is a major source of spectral line broadening in liquid state nano-scale nuclear magnetic resonance with shallow nitrogen-vacancy centres, whose main consequence is a limited spectral resolution. This limitation arises by virtue of the wi
Non-signalling conditions encode minimal requirements that any (quantum) systems must satisfy in order to be consistent with special relativity. Recent works have argued that in scenarios involving more than two parties, correlations compatible with rela
Non-signalling conditions encode minimal requirements that any (quantum) systems must satisfy in order to be consistent with special relativity. Recent works have argued that in scenarios involving more than two parties, correlations compatible with relativistic causality do not have to satisfy all poss...
In this paper we discuss and compare different signalling and routing methods for multiple-input multiple-output (MIMO) relay networks in terms of the netw... Y Fan,J Thompson - 《IEEE Trans Wireless Commun》 被引量: 905发表: 2007年 Performance analysis of beamforming in two hop amplify and...
We provide a unified framework for nonsignalling quantum and classical multipartite correlations, allowing all to be written as the trace of some local (quantum) measurements multiplied by an operator. The properties of this operator define the corresponding set of correlations. We then show that ...
Quantum theory is not only successfully tested in laboratories every day but also constitutes a robust theoretical framework: small variations usually lead to implausible consequences, such as faster-than-light communication. It has even been argued that quantum theory may be special among possible theo...
Complementarity between signalling and local indeterminacy in quantum nonlocal correlations The correlations that violate the CHSH inequality are known to have complementary contributions from signaling and local indeterminacy. This complementarit... S Aravinda,R Srikanth - 《Quantum Information & Computatio...
However, for systems in which superluminal signalling is heavily supressed (for example for systems restricted to sufficiently weak local interactions), R can still be expected to approximate a conventional density matrix. This is due to the fact that if measurements are spacelike separated, then ...
