A physical qubit is a physical device that behaves as a two-state quantum system, used as a component of a computer system. [ 1 ] [ 2 ] A logical qubit is a physical or abstract qubit that performs as specified in a quantum algorithm or quantum circuit [ 3 ] subject to unitary transformations , has a long enough coherence time to be usable by ...
The general definition of a qubit as the quantum state of a two-level quantum system.In quantum computing, a qubit (/ ˈ k juː b ɪ t /) or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device.

Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
Yoshihisa Yamamoto and K. Igeta propose the first physical realization of a quantum computer, including Feynman's CNOT gate. [17] Their approach uses atoms and photons and is the progenitor of modern quantum computing and networking protocols using photons to transmit qubits and atoms to perform two-qubit operations.
Former Google CEO Eric Schmidt says human-directed AI-controlled drones are the future of war. Schmidt's startup, White Stork, is developing drones for Ukraine to use in its war with Russia.
Costco has issued a recall for a cold and flu medication, sold at its stores at the end of 2024, over concerns of contamination.. The retail giant, in an advisory issued on Jan. 2, said Kirkland ...
A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
