Quantum
entanglement is a physical phenomenon that occurs when pairs or groups
of particles are generated or interact in ways such that the quantum
state of each particle cannot be described independently—instead, a
quantum state may be given for the system as a whole.

Measurements
of physical properties such as position, momentum, spin, polarization,
etc. performed on entangled particles are found to be appropriately
correlated. For example, if a pair of particles is generated in such a
way that their total spin is known to be zero, and one particle is found
to have clockwise spin on a certain axis, then the spin of the other
particle, measured on the same axis, will be found to be
counterclockwise. Because of the nature of quantum measurement, however,
this behavior gives rise to effects that can appear paradoxical: any
measurement of a property of a particle can be seen as acting on that
particle (e.g. by collapsing a number of superimposed states); and in
the case of entangled particles, such action must be on the entangled
system as a whole. It thus appears that one particle of an entangled
pair "knows" what measurement has been performed on the other, and with
what outcome, even though there is no known means for such information
to be communicated between the particles, which at the time of
measurement may be separated by arbitrarily large distances
