Quantum cryptography - Wikipedia
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.
Quantum Cryptography and Quantum Encryption Explained ...
Quantum cryptography uses the laws of quantum physics to transmit private information in a way that makes undetected eavesdropping impossible. Quantum key distribution (QKD), the most widely studied and viable method of quantum cryptography, uses a series of photons to transmit a secret, random sequence, known as the key.
What Is Quantum Cryptography? - IBM
Dec 1, 2023 · Quantum cryptography (also known as quantum encryption) refers to various cybersecurity methods for encrypting and transmitting secure data based on the naturally occurring and immutable laws of quantum mechanics.
NIST Releases First 3 Finalized Post-Quantum Encryption ...
Aug 13, 2024 · NIST has released a final set of encryption tools designed to withstand the attack of a quantum computer. These post-quantum encryption standards secure a wide range of electronic information, from confidential email messages to e-commerce transactions that propel the modern economy.
NIST Announces First Four Quantum-Resistant Cryptographic ...
Jul 5, 2022 · The first four algorithms NIST has announced for post-quantum cryptography are based on structured lattices and hash functions, two families of math problems that could resist a quantum computer's assault.
Quantum Cryptography & Encryption: What It Is & How It Works
Oct 23, 2020 · Quantum cryptography is a science that applies quantum mechanics principles to data encryption and data transmission so that data cannot be accessed by hackers – even by those malicious actors that have quantum computing of their own.
What is Quantum Cryptography? - TechTarget
Quantum cryptography is a system that is completely secure against being compromised without the knowledge of the message sender or the receiver. That is, it is impossible to copy or view data encoded in a quantum state without alerting the sender or receiver.
