Quantum superposition — is the fundamental law of quantum mechanics. It defines the allowed state space of a quantum mechanical system.In Probability theory, every possible event has a positive number associated to it, the probability, which gives the chance that it… … Wikipedia
Quantum reflection — is a physical phenomenon involving the reflection of a matter wave from an attractive potential. In classical physics, such a phenomenon is not possible; for instance when one magnet is pulled toward another, you do not expect one of the magnets… … Wikipedia

Excited state — Excitation is an elevation in energy level above an arbitrary baseline energy state. In physics there is a specific technical definition for energy level which is often associated with an atom being excited to an excited state.In quantum… … Wikipedia
Quantum Zeno effect — The quantum Zeno effect is a name coined by George Sudarshan and Baidyanaith Misra of the University of Texas in 1977 in their analysis of the situation in which an unstable particle, if observed continuously, will never decay.Citation | last =… … Wikipedia
Quantum field theory — In quantum field theory (QFT) the forces between particles are mediated by other particles. For instance, the electromagnetic force between two electrons is caused by an exchange of photons. But quantum field theory applies to all fundamental… … Wikipedia
State of matter — A state of matter (or physical state, or form of matter) has physical properties which are qualitatively different from other states of matter.Traditionally, three states of matter were recognized: solid, which maintains a fixed volume and shape; … Wikipedia
Quantum dot cellular automaton — Quantum Dot Cellular Automata (sometimes referred to simply as quantum cellular automata, or QCA) Any device designed to represent data and perform computation, regardless of the physics principles it exploits and materials used to build it, must … Wikipedia
Quantum well infrared photodetector — A quantum well infrared photodetector (QWIP), is an infrared photodetector made from semiconductor materials which contain one or more quantum wells. These can be integrated together with electronics and optics to make infrared cameras for… … Wikipedia
