Helstrom theorem from the no-signaling condition

Won-Young Hwang

Published Jun 14, 2005• 27 citations

Abstract

We prove a special case of Helstrom theorem by using no-signaling condition in the special theory of relativity that faster-than-light communication is impossible.

Faster-Than-Light Communication using Quantum Entanglement is Possible

Florentín Smarandache

In this little note we refute the statement that Faster-Than-Light Communication using Quantum Entanglement is Impossible, by proving that the alleged proof of the mainstream is irrelevant. Also, the Faster-Than-Light Communication does NOT mean sending information into the past. We recall the many paradoxes of the theory of relativity that make it unrealistic, while the Absolute Theory of Relativity [1] is the realistic one.

Non Spin Based Quantum Information Transmission Methods

Omer Dickstein

Most physicists claim no superluminal communication between two seperate points in space is possible in any manner. This claim is based on the no communication theory and on special relativity stating all communication methods are subluminal. This paper discusses theoretical 'holes' in no communication theorem and proposes an experiment that may check the validity of the no-communication theorem under special conditions.

Coexistence of Quantum Theory and Special Relativity in Signaling Scenarios

Pedro Sancho

The coexistence between Quantum Mechanics and Special Relativity is usually formulated in terms of the no-signaling condition. Several authors have even suggested that this condition should be included between the basic postulates of Quantum Theory. However, there are several scenarios where signaling is, in principle, possible: based on previous results and the analysis of the relation between unitarity and signaling we present an example of a two-particle interferometric arrangement for which the dynamics is, in principle, compatible with superluminal transmission of information. This type of non-locality is not in the line of Bell's theorem, but closer in spirit to the one-particle acausality studied by Hegerfeldt and others. We analyze in this paper the meaning of this non-locality and how to preserve the coexistence of the two fundamental theories in this signaling scenario.

EPR Paradox Solved by Special Theory of Relativity

Justin Lee

This paper uses the special theory of relativity to introduce a novel solution to EinsteinPodolskyRosen paradox.More specically, the faster-than-light communication is described to explain two types of EPR paradox experiments: photon polarization and electronpositron pair spins.Most importantly, this paper explains why this faster-than-light communication does not violate the special theory of relativity.

Unknowable Matters: How Nature's Speed Limit on Communication Relates to Quantum Physics

Stephen McAdam

It is shown that there is no way of identifying an unknown polarization state of a photon by proving that otherwise faster than light communication would be possible. It is similarly argued that the “no cloning theorem” of quantum physics must be true.
