A Theory of Quantum Superluminal Communication

Shan Gao

Published Jan 1, 2004• 0 citations
OpenAlex

Abstract

The implications of quantum nonlocality are briefly reviewed. It is shown that the collapse of the wave function requires the existence of a preferred Lorentz frame. This opens the first door to quantum superluminal communication (QSC). A theory of QSC is deeply analyzed. We demonstrate that the combination of the collapse of the wave function and the consciousness of the observer will permit the observer to distinguish nonorthogonal states under some condition. This provides a principle for realizing QSC. A practical QSC scheme is given based upon the QSC principle. Some evidence of the existence of QSC is also discussed. Besides, a new space-time transformation for QSC is analyzed, and two ways to measure the preferred Lorentz frame are given.

On the possibility of nonlinear quantum evolution and superluminal communication

Shan Gao

A possible mechanism of nonlinear quantum evolution is introduced and its implications for quantum communication are investigated. First, it is argued that an appropriate combination of wavefunction collapse and the consciousness of observer may permit the observer to distinguish nonorthogonal quantum states in principle, and thus consciousness will introduce certain nonlinearity into quantum dynamics. Next, it is shown that the distinguishability of nonorthogonal states can be used to achieve quantum superluminal communication, by which information can be transmitted nonlocally and faster than the speed of light. Finally, the issue of apparent incompatibility between superluminal communication and special relativity is briefly addressed.

Quantum superluminal communication does not result in the causal loop

Shan Gao

We show that the quantum superluminal communication based on the quantum nonlocal influence, if exists, will not result in the causal loop, this conclusion is essentially determined by the peculiarity of the quantum nonlocal influence itself, according to which there must exist a preferred Lorentz frame for consistently describing the quantum nonlocal process.

How to realize quantum superluminal communication?

Shan, Gao

We deeply analyze the possibility to achieve quantum superluminal communication beyond the domain of special relativity and present quantum theory, and show that when using the conscious object as one part of the measuring device, quantum superluminal communication may be a natural thing.

Some Thoughts on Quantum Nonlocality and Its Apparent Incompatibility with Relativity

Shan Gao

It may well be that a relativistic version of the theory, while Lorentz invariant and local at the observational level, may be necessarily non-local and with a preferred frame (or aether) at the fundamental level. – John Bell [1] Introduction Bell's theorem establishes a contradiction between locality (and a few other assumptions) and certain predictions of quantum mechanics [2]. There have been two main issues surrounding the deep implications of this celebrated theorem. The first issue is basic, and it concerns whether the theorem really establishes that nonlocality is a necessary feature of any empirically viable theory and hence a feature of nature itself. One aspect of the issue concerns exactly what the underlying assumptions of Bell's theorem are. For example, some argue that these assumptions include the assumption of counterfactual definiteness [3–5], while others disagree [6–8]. The other aspect of the issue concerns which assumption should be dropped due to the resulting contradiction. Some believe that standard quantum mechanics may avoid nonlocality by denying counterfactual definiteness [3–5]. The second issue is much deeper, and it concerns how to make sense of the strange nonlocality when assuming that Bell's theorem establishes that our world is nonlocal. In particular, it has yet to be determined whether such quantum nonlocality is compatible with the theory of relativity, e.g., whether the nonlocality requires the existence of a preferred Lorentz frame [7, 9, 10]. It seems that “there is a preferred frame of reference, and in this preferred frame of reference things do go faster than light … Behind the apparent Lorentz invariance of the phenomena, there is a deeper level which is not Lorentz invariant” [11]. But it also seems possible that the existence of a preferred Lorentz frame is an illusion, since it cannot be detected according to standard quantum mechanics. A more subtle issue is whether quantum nonlocality permits superluminal signaling. It is widely thought that the answers to these questions will lead to a deeper understanding of Bell's theorem and quantum nonlocality. In this paper, we will present a new analysis of quantum nonlocality and its apparent incompatibility with relativity.

Identification and collapse---the seeds of quantum superluminal communication

Shan, Gao

We deeply analyze the relation between the identification process of the classical definite states and collapse process of the measured superposition state of such definite states, and show that these two processes are essentially irrelevant, which then provides one possibility to achieve quantum superluminal communication.

Simple Superluminal Entangled Communication and Its Base of Complete Special Relativity, Extensive Special Relativity and Quantum Theory

Yi-Fang Chang

Based on quantum entanglement and corresponding quantum communication, first we research a simple superluminal entangled communication scheme, whose key is to establish two mutually entangled particles or devices A and B. We observe and control the information of A position, then can know the corresponding results of the other B. This is not to send directly information each other. It may be superluminal. Next, in special relativity we provided that there are necessarily two symmetrical topological structures separated by the light-cone, which includes the generalized Lorentz transformation (GLT) for the spacelike interval, in which phase velocity is superluminal.
