In quantum mechanics, each [quantum state]? is identified with a vector in a Hilbert space. Paul Dirac introduced the bra-ket notation as a concise and convenient way to describe quantum states:

In quantum mechanics, each [quantum state]? is identified with a vector in a Hilbert space. Paul Dirac introduced the bra-ket notation as a concise and convenient way to describe quantum states. The terminology comes from the fact that the central operation looks like a "bracket" <φ|ψ> consisting of a left part, the "bra" <φ|, and a right part, the "ket" |ψ>.
