quantum state

[′kwän·təm ‚stāt] (quantum mechanics) The condition of a physical system as described by a wave function; the function may be simultaneously an eigenfunction of one or more quantum-mechanical operators; the eigenvalues are then the quantum numbers that label the state. energy state

quantum state

A fundamental attribute of particles according to quantum mechanics. The quantum states are primarily x-y-z position, momentum, angular momentum, energy, spin and time.

Fermions
The shell structures of the atom are made up of fermion particles, which include the protons and neutrons in the nucleus and the electrons in the outer orbits. Fermions cannot share the same quantum state variables. For example, every electron traveling in electric current has a different quantum state than the electron next to it. The fermion was named after Italian physicist Enrico Fermi (1901-1954).

Bosons
Bosons are particles that can be in the same quantum state. Photons are examples of bosons, and lasers, masers and the superfluidity Helium derive their behavior as a result. The boson, pronounced "bow-son," was named after Indian physicist Satyendra Nath Bose (1894-1974). See quantum mechanics, electron, photon and Higgs boson.

单词	quantum state
释义	quantum state quantum state n. Any of the possible states of a system described by quantum theory. quantum state n (Atomic Physics) physics a state of a system characterized by a set of quantum numbers and represented by an eigenfunction. The energy of each state is precise within the limits imposed by the uncertainty principle but may be changed by applying a field of force. States that have the same energy are called degenerate.
