An Introduction to Quantum Computing (Noson S. Yanofsky, arXiv.org)
Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. A quantum computer is a device that performs quantum computing. They are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can be in superpositions of states. A quantum Turing machine is a theoretical model of such a computer, and is also known as the universal quantum computer. — Wikipedia

- Bristol team chase down advantage in quantum raceon January 26, 2022 at 7:39 pm
Quantum researchers have dramatically reduced the time to simulate an optical quantum computer, with a speedup of around one billion over previous approaches.
- A leap forward for terahertz laserson January 26, 2022 at 5:24 pm
Researchers have taken a major step towards bringing terahertz frequencies out of their hard-to-reach region of the electromagnetic spectrum and into everyday applications. Researchers demonstrate a first-of-its-kind terahertz laser that is compact, operates at room temperature and can produce 120 individual frequencies spanning the 0.25 - 1.3 THz, far more range than previous terahertz sources.
- Quantum computing: Vibrating atoms make robust...on January 26, 2022 at 5:24 pm
Physicists have discovered a new quantum bit, or 'qubit,' in the form of vibrating pairs of atoms known as fermions. The new qubit appears to be extremely robust, able to maintain superposition between two vibrational states, even in the midst of environmental noise, for up to 10 seconds, offering a possible foundation for future quantum computers.
- Physicist solves century old problem of radiation...on January 25, 2022 at 5:40 pm
A physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field. This question has challenged physicists for over 100 years but a mathematical physicist has suggested an alternative approach, with controversial implications.
- Studying the Big Bang with artificial intelligenceon January 25, 2022 at 2:30 pm
Artificial intelligence is being used for many extremely complex tasks. So why not use machine learning to study particle physics? As it turns out, this is not easy, because of some special mathematical properties of particle physics. But now, a neural network has been developed that can be used to study quark gluon plasma - the state of the universe after the Big Bang.
