Is the Consequence of Superluminal Signalling to Physics Absolute Motion through an Ether
In an earlier paper the author expounded an interferometer scheme to communicate classical data over an entangled quantum channel. We return to this concept to show that the laws of Quantum Mechanics
Entanglement, Nonlocality, Superluminal Signaling and Cloning
The paper is a Chapter of a book. In it an exhaustive review of the proposals to send faster than light signals resorting to quantum nonlocality and the reduction process is presented, together with
On a Recent Proposal of Faster than Light Quantum Communication
In a recent paper, A.Y. Shiekh has discussed an experimental set-up which, in his opinion, should make possible faster-than-light communication using the collapse of the quantum wave function.
Analysis of single-particle nonlocality through the prism of weak measurements
Although regarded today as an important resource in quantum information, nonlocality has yielded over the years many conceptual conundrums. Among the latter are nonlocal aspects of single particles
How the Quantum no-Communication Theorem Misuses the Formalism and Loses Phase Information
This paper follows on from the author’s previous thoughts on the subject of the “No-communication Theorem” and Ghirardi’s critique of a communication scheme by the author and then his response to
Begging the signalling question: quantum signalling and the dynamics of multiparticle systems
The abundant experimental confirmation of Bell’s Theorem has made a compelling case for the nonlocality of quantum mechanics (QM), in the precise sense that quantum phenomena exhibit correlations
The rastall model and Stapp's proof of nonlocality
Recently two distinct arguments have been given (by Stapp, and Bedford and Stapp) to prove that a model proposed by Rastall for the statistics of EPR-correlated spin-1/2 particles, which happens to
Superluminal Signalling without the use of Entangled Particles
Entanglement studies dwell on multi-particle systems by definition – one particle, via a global symmetry/conservation law is correlated to another. It has often been wondered via
Quantum Formalism with State-Collapse and Superluminal Communication
Given the collapse hypothesis (CH) of quantum measurement, EPR-type correlations along with the hypothesis of the impossibility of superluminal communication (ISC) have the effect of globalizing
Efficient Quantum Teleportation of Unknown Qubit Based on DV-CV Interaction Mechanism
TLDR
All measurement outcomes of the quantum teleportation are distinguishable, but the teleported state at Bob’s disposal may acquire a predetermined amplitude-distorting factor.
