In another essay, I’ve argued by means of a formal analogy between (i) the incompleteness of Principia Mathematica-style systems of mathematical logic (logico-mathematical incompleteness) and (ii) the incompleteness of the Standard Models in contemporary physics (physico-mechanical incompleteness), that (iii) just as the fact of logico-mathematical incompleteness entails the existence of mathematical creativity, so too the fact of physico-mechanical incompleteness entails the existence of natural creativity. Building on that line of thought, in this essay I present a new and empirically-testable strategy for completing quantum mechanics. More precisely, I argue that if we assume that the Standard Models in contemporary physics are incomplete, and if we also assume that all rational human animals are primitive sources of natural creativity via their free agency, then, by means of an appeal to Bohmian mechanics, together with the thesis that all rational human animals are primitive sources of natural creativity via their free agency, we can complete quantum mechanics.

The aim of the present paper is to sbo» that anti-realism in science, 1vhich has a1;guab/y become more fashionable in recentyears, contrary to tuha: its proponents assert, cannot make use of quantum mechanics and its impressiue achievements as a frump card in justifying its claims. I will argue that scientific anti-realism far from providing scientific communiry with a progressive methodologicalframeuorle is a restrictive approach wbicb would hamper scientific progress. Focusing on the historical evidence of the 1vqys in subicb quantum mechanics was deueloped, I 1vill further argue that the orthodox interpretation of quantum mechanics due to Bohr and Heisenberg, among others, iuith its in-built anti-realistic elements provides a damning verdict against the claims of anti-realists. Following a critical assessment of a number of alternative interpretations or the calculus of quantum mechanics, I shall present realistic approaches which provide more effective and frudful conceptualframeu;orks for the advancement of research in the quantum

John Barth’s “Menelaiad” and Quantum Mechanics: The Sacrifice of Common Sense(مقاله علمی وزارت علوم)

In the annals of the Greek myth, there has been a lacuna surrounding Menelaus and Helen’s relationship following the sack of Troy. What distinguishes Barth’s retelling of the Greek myth is filling this void through constructing a posthistory to the relationship the couple bear to each other and his giving voice to the concerns of Menelaus, a character who has always been in the recess of the canon. While a large body of research has approached Barth’s “Menelaiad” in light of literature of the absurd, this study, through adopting the stance of quantum mechanics on the nature of reality, will demonstrate that Barth’s work is anything but absurd. Establishing the framework of the article based on the uncertainty principle of quantum mechanics, the present study argues how the adoption of the subatomic reality, implied in Proteus’ advice, allows Menelaus to jettison his festering obsession with the causality behind Helen’s choice and re-embrace her.

Background: Quantum Key Distribution (QKD) has turned into a crucial point for secure communication in the era of quantum networks. Quantum key distribution provides the client with a theoretically secure key by taking advantage of the principles of quantum mechanics to counteract what could be posed by quantum computing to classical cryptography. Photons are lost in the system and there are some limitations which don’t allow scalability and integration with already existing networks. Objective: The study seeks to assess the viability of QKD systems, review some of the challenges associated with it, and investigate possible methods of utilizing both QKD and PQC to cope with new security threats in telecommunication industry. Methods: An in-depth analysis was made based on the experimental observations of key generation rates, photon loss, error correction, data throughput, and latency. Performance of quantum repeaters was experimented with for the purposes of measuring distance improvement abilities. A combined QKD-PQC approach was assessed for integrated integration for restricted settings. Results: QKD was seen to have high security and high performance in short distances and when quantum repeaters were implemented the distance could be greatly enhanced. In the QKD-PQC model, the rate of error correction, throughput, and scalability was noticed to be higher than in standalone QKD. Challenges that faced the work were photon loss, processing latency, and system vulnerabilities. Conclusion: New opportunities for secure communication are opened with QKD supported by quantum repeaters and hybrid cryptographic approaches. The technical and operational issues need to be resolved to realize the potential role of B3G evolution in enabling global telecommunications for the mass market.
