In a proposed communication scheme, quantum entanglement and quantum nonlocality would be utilized to effect instantaneous transmission of randomly chosen messages to remote locations. Although the messages would not convey any information, they might nevertheless be of some value under circumstances in which deception and secrecy are of more importance than are the specific contents of the messages.
The scheme would be implemented in a simple quantum algorithm: The sender and recipient would each possess n particles, each of which could be in one of two equally probable quantum states denoted "+" and "–" (e.g., corresponding to spin up or spin down if the particles were electrons). Each particle at the sender's location would be paired with one of particles at the recipient's location by a quantum entanglement.
The sender and recipient would both perform a timed sequence of measurements on their particles — one particle per time step — so that at the end of n time steps, the sender and recipient would both possess n-length sequences of "+" and "–" readings. By performing the measurements, the sender would have randomly selected one of the 2n possible sequences. The sequence would constitute a randomly chosen message. Because of quantum entanglement, the recipient's sequence would be uniquely correlated with the sender's sequence.
Given the randomness of the selection, the message would convey no information. The message may nevertheless have value under circumstances in which any of the 2n possible messages would be equally effective in producing a desired outcome and there is a requirement to keep the message (that is, the randomly chosen sequence of "+" and "–" secret from everyone except the intended recipient. In such circumstances, the value would lie in secrecy and/or deception: the random selection would hide the actual message among 2n–1 other messages.

Overview
The document titled "Quantum Superluminal Communications" by Michail Zak, prepared for NASA's Jet Propulsion Laboratory, presents a novel approach to instantaneous message transmission based on quantum entanglement. The core idea revolves around utilizing quantum nonlocality, a fundamental and enigmatic phenomenon in quantum mechanics, to achieve rapid communication over vast distances.
The abstract outlines the proposal of a simple algorithm that enables the instantaneous transmission of randomly chosen messages. This concept is rooted in the principles of quantum information theory, which has seen successful applications in areas such as teleportation, cryptography, and computing. However, the document highlights a significant limitation: traditional quantum teleportation methods require an additional classical communication channel, as the messages transmitted through quantum entanglement do not convey Shannon information, which is tied to the unpredictability of outcomes.
Zak emphasizes that while quantum messages may not deliver conventional information, they could still possess value in contexts where attributes like secrecy or deception are relevant. This perspective broadens the understanding of what constitutes useful information, especially in biological or social systems where intentional misdirection can occur.
The document also discusses the implications of quantum nonlocality, which, despite being experimentally validated, remains conceptually challenging. The author suggests that exploring alternative measures of information delivery beyond Shannon's framework could unlock new applications for quantum communication.
In terms of technical disclosure, the document outlines the novelty of the proposed work, asserting that it represents a significant advancement in communication technology by exploiting a known physical effect of quantum entanglement. The motivation behind this research is to enhance communication capabilities, addressing the limitations of existing methods.
Overall, the document serves as a technical support package detailing the potential of quantum superluminal transmission, inviting further exploration into its applications and implications. It underscores the need for a deeper understanding of quantum mechanics and its potential to revolutionize communication, particularly in scenarios where traditional information transfer methods fall short. The work was conducted under NASA's auspices, emphasizing its significance in advancing scientific knowledge and technology.
