Qubits, Atoms, Photons, Entanglements, Quantum Mechanics and Diamonds meet the Information Age. Current research indicates that diamonds may hold the key to a cryptanalyst's nightmare, 'The unbreakable cipher'. This paper introduces the basic theory and principles behind this innovative technology, reports on the research that has led to present day breakthroughs, investigates those that hold promise and looks at the possibilities for future research in this field. This report is presented as a primer to the 'World of Quantum Cryptography' and its impact on Network Security and Management. Consequently, it does not provide any mathematical proofs behind the theoretical models which relate to Quantum Mechanics. It does, however, make reference to and direct those who require this depth of knowledge to the sources if this information is desired or is the basis for further research.

Quantum cryptography is an emerging technology in which two parties can secure network communications by applying the phenomena of quantum physics. The security of these transmissions is based on the inviolability of the laws of quantum mechanics. Quantum cryptography was born in the early seventies when Steven Wiesner wrote "Conjugate Coding", which took more than ten years to end this paper. The quantum cryptography relies on two important elements of quantum mechanics - the Heisenberg Uncertainty principle and the principle of photon polarization. The Heisenberg Uncertainty principle states that, it is not possible to measure the quantum state of any system without distributing that system. The principle of photon polarization states that, an eavesdropper can not copy unknown qubits i.e. unknown quantum states, due to no-cloning theorem which was first presented by Wootters and Zurek in 1982. This research paper concentrates on the theory of quantum cryptography, and how this technology contributes to the network security. This research paper summarizes the current state of quantum cryptography, and the real-world application implementation of this technology, and finally the future direction in which the quantum cryptography is headed forwards.

The uses of computer communications networks technologies have increased the incidents of computer abuse. Because of these incidents, most organizations facing pressure to protect their assets. Most digital networks generally rely on modern cryptosystems to secure the confidentiality and integrity of traffic carried across the network. The current modern cryptosystems based on mathematical model introduce potential security holes related to technological progress of computing power, the key refresh rate and key expansion ratio, the most crucial parameters in the security of any cryptographic techniques. For that reason efforts have been made to establish new foundation for cryptography science in the computer communications networks. One of these efforts has led to the development of quantum cryptography technology, whose security relies on the laws of quantum mechanics [1,2,3,20, 24]. This research paper concentrates on quantum cryptography, and how this technology contributes to the network security. The scope of this research paper is to cover the weaknesses, and the security pitfalls in modern cryptography, fundamental concepts of quantum cryptography, the real - world application implementation of this technology, finally the future direction in which the quantum cryptography is headed forwards.
The exponential increase in data transmission and the rise of quantum computing threaten classical encryption systems, necessitating a paradigm shift in secure communication. Quantum cryptography, particularly Quantum Key Distribution (QKD), exploits the principles of quantum mechanics to enable theoretically unbreakable security. This paper explores the foundational theories, key technologies, real-world implementations, current challenges, and future trajectories of quantum cryptography. Emphasis is placed on QKD protocols, entanglement-based communication, and integration with existing infrastructure. The study also evaluates potential vulnerabilities and the global movement toward quantum-resilient security systems.
In the last few decades, cryptographic algorithms have been based on the fundamental operation of factoring large integers into their primes, which is considered to be “INTRACTABLE,” but contemporary cryptography is vulnerable to both technological advancements in computing power and mathematical advances that enable swift reversal of one-way functions like that of factoring large integers. Therefore, the approach is to include quantum physics into encryption, which results in an assessment of quantum cryptography. One of the newest areas in the realm of computer science is quantum cryptography. By using the principles ofquantum physics, two parties can use this important technology to protect network connections.The principles of quantum mechanics provide a theoretical foundation for highly securecommunication systems. This paper summarizes the current state of quantum cryptography,the implementation of this technology in real-world applications, and finally the direction inwhich the quantum cryptography is headed forward. Quantum cryptography (QC) is basedon two key aspects of quantum mechanics: first one is the Heisenberg Uncertainty Principleand second one is the Principle of Photon Polarization. To provide a unified perspective ofsecure communication technologies, this survey introduces a taxonomy that relates classical,modern, and quantum cryptographic paradigms and classifies major quantum cryptographicprimitives, protocols, and emerging quantum networking technologies.
Alan Turing has certainly contributed to a widespread belief that the quest for a perfect, unbreakable, cipher is a futile pursuit. The ancient art of concealing information has, in the past, been matched by the ingenuity of code-breakers, but no longer! With the advent of quantum cryptography, the hopes of would-be eavesdroppers have been dashed, perhaps for good. Moreover, recent research, building on schemes that were invented decades ago to perform quantum cryptography, shows that secure communication certified by a sufficient violation of a Bell inequality makes a seemingly insane scenario possible-devices of unknown or dubious provenance, even those that are manufactured by our enemies, can be safely used for secure communication, including key distribution. All that is needed to implement this bizarre and powerful form of cryptography is a loophole-free test of a Bell inequality, which is on the cusp of technological feasibility. We provide a brief overview of the intriguing connections between Bell inequalities and cryptography and describe how studies of quantum entanglement and the foundations of quantum theory influence the way we may protect information in the future.
