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.
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 ...
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 ...

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.
A phase qubit is a current-biased Josephson junction, operated in the zero voltage state with a non-zero current bias. A Josephson junction is a tunnel junction, [6] made of two pieces of superconducting metal separated by a very thin insulating barrier, about 1 nm in thickness.
Bisection of linear array network. For ring topology with n nodes two links should be broken to bisect the network, so bisection bandwidth becomes bandwidth of two links. Bisection of a ring network. For tree topology with n nodes can be bisected at the root by breaking one link, so bisection bandwidth is one link bandwidth. Bisection of a tree ...
