The Quantum Communications Hub is a quantum technology research hub established as part of the UK National Quantum Technologies Programme. The hub is a consortium of 8 UK universities and 13 industrial partners, which received funding of £24m over a 5-year period. [1] The hub will develop techniques for quantum key distribution (QKD), and in ...
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.
That these codes allow indeed for quantum computations of arbitrary length is the content of the quantum threshold theorem, found by Michael Ben-Or and Dorit Aharonov, which asserts that you can correct for all errors if you concatenate quantum codes such as the CSS codes—i.e. re-encode each logical qubit by the same code again, and so on, on ...
This list contains quantum processors, also known as quantum processing units (QPUs). Some devices listed below have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance. Quantum processors are difficult to compare due to the different architectures and approaches.
For resiliency against quantum computers, sizes of =, =, = with Goppa code were proposed, giving the size of public key of 8 373 911 bits. [10] In its round 3 submission to the NIST post quantum standardization the highest level of security, level 5 is given for parameter sets 6688128, 6960119, and 8192128.
In cryptography, Combined Elliptic-Curve and Post-Quantum 2 (CECPQ2) is a quantum secure modification to Transport Layer Security (TLS) 1.3 developed by Google. It is intended to be used experimentally, to help evaluate the performance of post quantum key-exchange algorithms on actual users' devices.
IBM Quantum Platform (previously known as IBM Quantum Experience) is an online platform allowing public and premium access to cloud-based quantum computing services provided by IBM. This includes access to a set of IBM's prototype quantum processors, a set of tutorials on quantum computation, and access to an interactive textbook.
Quantum suicide is a thought experiment in quantum mechanics and the philosophy of physics. Purportedly, it can falsify any interpretation of quantum mechanics other than the Everett many-worlds interpretation by means of a variation of the Schrödinger's cat thought experiment, from the cat's point of view.
