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. The advantage of quantum cryptography lies in the fact that it ...
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 · Like quantum cryptography, quantum computing is a rapidly emerging technology that also harnesses the laws of quantum mechanics. Compared to our fastest and most cutting-edge classical computers, quantum computers have the potential to solve complex problems orders of magnitude faster.
What is Quantum Cryptography? - TechTarget
Quantum cryptography is a method of encryption that uses the naturally occurring properties of quantum mechanics to secure and transmit data in a way that cannot be hacked. Cryptography is the process of encrypting and protecting data so that …
Quantum Cryptography - GeeksforGeeks
Mar 21, 2023 · Quantum Cryptography works on the principle of quantum entanglement, which is a phenomenon where two particles are correlated in a way that the state of one particle affects the state of the other particle, even when they are separated by a large distance.
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-Safe Cryptography? - IBM
Sep 4, 2024 · It's worth noting that some people also refer to quantum-safe cryptography as post-quantum computing (PQC) or quantum-resistant computing. According to NIST, this type of IT security "aims to "develop cryptographic systems that are secure against both quantum and classical computers, and can interoperate with existing communications protocols ...
Cryptography in the Quantum Age | NIST - National Institute of ...
Mar 21, 2018 · Quantum cryptography is designed to protect communications between two trustworthy parties from being intercepted by an eavesdropper. But what if the person on the other side is a cyberattacker? Eavesdroppers are currently not the biggest concern in cybersecurity.
