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.
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.
The AES-256 and SHA-384 algorithms are symmetric, and believed to be safe from attack by a large quantum computer." [20] In a 2022 press release, the NSA notified: "A cryptanalytically-relevant quantum computer (CRQC) would have the potential to break public-key systems (sometimes referred to as asymmetric cryptography) that are used today.
Quantum computers might soon actually be useful, researchers have said after a new breakthrough. A new study showed that a quantum computer could be used for calculations that are beyond the ...
The qubits in quantum computing are more prone to mistakes than a regular computer because they are highly sensitive to electromagnetic and other forms of interference and can only remain in a ...
Neuromorphic quantum computing (abbreviated as ‘n.quantum computing’) is an unconventional computing type of computing that uses neuromorphic computing to perform quantum operations. It was suggested that quantum algorithms, which are algorithms that run on a realistic model of quantum computation, can be computed equally efficiently with ...
This article lists the companies worldwide engaged in the development of quantum computing, quantum communication and quantum sensing. Quantum computing and communication are two sub-fields of quantum information science , which describes and theorizes information science in terms of quantum physics .
Quantum computing was one of the hot trends of the past few months as stocks have doubled or more following Alphabet's (NASDAQ: GOOG) Willow announcement. Investors looking for any way to play the ...
