Bell state

noun

(quantum information science) One of a set of four entangled states, namely |𝛷⁺⟩=1/√(|00⟩+|11⟩), |𝛷⁻⟩=1/√(|00⟩-|11⟩), |𝛹⁺⟩=1/√(|01⟩+|10⟩), and |𝛹⁻⟩=1/√(|01⟩-|10⟩), where |xy⟩:=|x⟩⊗|y⟩; these are the simplest examples of entangled states.

The Bell state is a fundamental concept in quantum mechanics.
