Entanglement
Entanglement is a physical phenomenon
that refers to the relation between two
or more particles — or, to generalize it,
qubits — that affect their properties
such that we can not describe the state
of one of them independently of the
others.
One of the most commonly used qubits is photon
spins. A photon can either have spin up (one
state) or spin down (zero states). If we have two
entangled photons, then they must have opposite
spins, if one is up then the other must be down.
