quantum system — /kwɒntəm ˈsɪstəm/ (say kwontuhm sistuhm) noun a physical or theoretical system which can only be described by quantum physics …
Open quantum system — In physics, an open quantum system is a quantum system which is found to be in interaction with an external quantum system, the environment. The open quantum system can be viewed as a distinguished part of a larger closed quantum system, the… … Wikipedia

Quantum indeterminacy — is the apparent necessary incompleteness in the description of a physical system, that has become one of the characteristics of the standard description of quantum physics. Prior to quantum physics, it was thought that (a) a physical system had a … Wikipedia
Quantum number — Quantum numbers describe values of conserved numbers in the dynamics of the quantum system. They often describe specifically the energies of electrons in atoms, but other possibilities include angular momentum, spin etc.Since any quantum system… … Wikipedia
Quantum cryptography — Quantum cryptography, or quantum key distribution (QKD), uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt… … Wikipedia
Quantum dissipation — is the branch of physics that studies the quantum analogous of the process of irreversible loss of energy observed at the classical level. Its main purpose is to derive the laws of classical dissipation from the framework of quantum mechanics. It … Wikipedia
Quantum Darwinism — is a theory explaining the emergence of the classical world from the quantum world as due to a process of Darwinian selection. It is proposed by Wojciech Zurek and a group of collaborators including Ollivier, Poulin, Paz and Blume Kohout. The… … Wikipedia
Quantum nondemolition measurement — Quantum nondemolition (QND) measurement is a measurement of a quantum system, which preserves the integrity of the system and the value of the measured observable. This allows exactly the same system to be measured repeatedly. The term… … Wikipedia
