What is Quantum Cryptography? Basic Information and Its Importance

Quantum cryptographyQuantum cryptography is an encryption method that ensures information security using the principles of quantum mechanics. Unlike classical cryptography methods, it relies on physical laws rather than mathematical complexity. This aims to provide a more secure solution against the threats of potential future computer technologies (especially quantum computers). Quantum cryptography has the potential to revolutionize cybersecurity, especially in situations where sensitive data must be protected.

Quantum cryptography is based on the exploitation of the quantum properties of photons (particles of light). These properties include superposition (the ability to exist in multiple states simultaneously) and entanglement (the interconnectedness of two photons, with the state of one instantly affecting the other). These properties are used to transmit information securely. If an eavesdropper attempts to monitor or measure the transmitted photons, this changes their state, which both the sender and receiver can detect. This allows for easy detection of unauthorized access.

Quantum key distribution (QKD)QKD is one of the most well-known applications of quantum cryptography. QKD enables the distribution of encryption keys over a secure communication channel. These keys are then used in conjunction with classical encryption algorithms to ensure the confidentiality of the communication. The biggest advantage of QKD is that any eavesdropping attempt is physically detectable. This provides a permanent solution to the key distribution problem, one of the weaknesses of classical cryptography.

The importance of quantum cryptography is becoming increasingly evident as today's cybersecurity threats continue to grow. In particular, the development of quantum computers threatens existing encryption methods. Quantum cryptographyBy providing a solution to this threat, quantum cryptography will play a critical role in meeting future information security needs.

How Does Quantum Cryptography Work? Basic Mechanisms

Quantum cryptographyUnlike classical encryption methods, quantum cryptography aims to provide secure communication using the fundamental principles of quantum mechanics. In this field, the encryption and transmission of information using quantum states (e.g., photon polarization) is fundamental. While traditional cryptography relies on mathematical challenges, quantum cryptography offers security derived from the laws of physics itself. In particular, concepts such as the Heisenberg Uncertainty Principle and Quantum Entanglement play a critical role in detecting and preventing unauthorized access.

One of the fundamental protocols used in this field is BB84. The BB84 protocol generates a key using the polarization of photons, which is then used in conjunction with classical encryption algorithms. Polarized photons are sent and measured between the sender (Alice) and the receiver (Bob) over a quantum channel. The polarization bases used are then shared over a classical channel. By eliminating erroneous or different measurements, a shared secret key is generated.

Basic Mechanisms

The fundamental mechanisms of quantum cryptography rely on the unique properties of quantum mechanics. Quantum key distribution (QKD)is one of the most important of these mechanisms. QKD ensures secure key transmission over a quantum channel. Eavesdropping attempts disrupt quantum states, which can be detected by both the sender and receiver. This allows unauthorized access to be detected, ensuring communication security.

Quantum Channel	Transmits quantum signals	Photons are sent to the receiver via fiber optic cables or free space.

Classic Channel	Enables information sharing	Used to verify which polarization bases are used.

Working Principles

• Quantum Superposition: A quantum bit (qubit) can carry the values 0 and 1 simultaneously.
• Heisenberg Uncertainty Principle: The inability to know with certainty the properties of a particle, such as its position and momentum, simultaneously.
• Quantum Entanglement: Two or more particles are connected together and the state of one instantly affects the other.
• Quantum Key Distribution (QKD): A method of generating and distributing secure keys based on the principles of quantum mechanics.
• Photon Polarization: Photons carry information by being encoded in different polarizations (horizontal, vertical, diagonal).
