Bell state

English

Named after John Stewart Bell (1928–1990), Irish physicist.

Bell state (plural Bell states)

(quantum information science) One of a set of four entangled states, namely ${\\displaystyle |\\Phi ^{+}\\rangle ={1 \\over {\\sqrt {2}}}(|00\\rangle +|11\\rangle )}$ , ${\\displaystyle |\\Phi ^{-}\\rangle ={1 \\over {\\sqrt {2}}}(|00\\rangle -|11\\rangle )}$ , ${\\displaystyle |\\Psi ^{+}\\rangle ={1 \\over {\\sqrt {2}}}(|01\\rangle +|10\\rangle )}$ , and ${\\displaystyle |\\Psi ^{-}\\rangle ={1 \\over {\\sqrt {2}}}(|01\\rangle -|10\\rangle )}$ , where ${\\displaystyle |xy\\rangle$ ; these are the simplest examples of entangled states.
