Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. [1] [2] The best known example of quantum cryptography is quantum key distribution, which offers an information-theoretically secure solution to the key exchange problem. The advantage of quantum cryptography lies in the fact that it ...
Post-quantum cryptography (PQC), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are currently thought to be secure against a cryptanalytic attack by a quantum computer.
A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, ... which underpins the security of public key cryptographic systems, ...
Many of the world's secrets, from individual finances to national security, rely on encryption. Major developments in quantum computing call for new security procedures, researchers told BI.
The process of quantum key distribution is not to be confused with quantum cryptography, as it is the best-known example of a quantum-cryptographic task. An important and unique property of quantum key distribution is the ability of the two communicating users to detect the presence of any third party trying to gain knowledge of the key.

Three-stage quantum cryptography protocol (2006) is a method of data encryption that uses random polarization rotations by the two authenticated parties, to continuously encrypt data using single photons and can also be used for exchanging keys, with the possibility of multi-photon quantum cryptography and the ability to address man-in-the ...
Kyber is a key encapsulation mechanism (KEM) designed to be resistant to cryptanalytic attacks with future powerful quantum computers.It is used to establish a shared secret between two communicating parties without an attacker in the transmission system being able to decrypt it.
