- "Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks."
A type of encryption that uses the properties of quantum mechanics to secure communications.
Quantum Mechanics: This is the foundation of quantum cryptography. It involves the study of the behavior of matter and energy at the quantum level.
Quantum Information Theory: This is the study of the principles underlying the processing, transmission and storage of quantum information.
Quantum Key Distribution: This is the key concept behind quantum cryptography. It involves the use of quantum mechanics to securely distribute a random key between two parties over a public channel.
Entanglement: This is a fundamental concept in quantum mechanics where two or more particles interact in such a way that their properties are correlated.
Bell's Theorem: This is a fundamental theorem in quantum mechanics that states that local hidden variables cannot explain the correlation between entangled particles.
Quantum Computing: This is the study of the principles underlying the design and implementation of quantum computers.
Cryptography: This is the study of the design and implementation of techniques for secure communication in the presence of third-party adversaries.
Classical Cryptography: This is the study of cryptographic techniques that do not rely on quantum mechanics.
Public-Key Cryptography: This is a cryptographic technique in which a pair of keys is used to encrypt and decrypt messages.
Post-Quantum Cryptography: This is the study of cryptographic techniques that are secure against quantum computers.
Quantum Key Distribution (QKD): QKD is a type of quantum cryptography that allows two parties to share a secret key over an insecure channel by exploiting the principles of quantum mechanics. This key can then be used to encrypt and decrypt messages securely.
Quantum Random Number Generation (QRNG): QRNG is a type of quantum cryptography that uses the randomness of quantum mechanics to generate truly random numbers, which can then be used for encryption.
Quantum Digital Signatures (QDS): QDS is a type of quantum cryptography that uses the unique properties of quantum mechanics to generate digital signatures that are extremely difficult to forge.
Quantum Teleportation: Quantum teleportation is a type of quantum cryptography that allows information to be transmitted between two parties instantaneously, without passing through any physical channel.
Quantum Cryptanalysis: Quantum cryptanalysis is a type of quantum cryptography that involves using quantum computers to break classical cryptographic systems.
Quantum Identity Verification: Quantum identity verification is a type of quantum cryptography that allows two parties to verify each other's identity in a secure and efficient manner.
Quantum Secure Direct Communication: Quantum Secure Direct Communication is a type of quantum cryptography that allows two parties to communicate directly with each other without the need for a third party or any intermediary infrastructure.
Quantum Oblivious Transfer: Quantum oblivious transfer is a type of quantum cryptography that allows two parties to transfer information in a way that ensures privacy, without revealing any information to the other party.
Quantum Money: Quantum money is a theoretical type of quantum cryptography that would allow secure transactions without the need for a trusted third party or digital signatures.
Quantum Entanglement: Quantum entanglement is a phenomenon in quantum mechanics where two particles can become intertwined in such a way that their states are linked, allowing for secure communication and cryptography.
