bra-ket

名詞

(physics) The product of two vectors (and optionally an operator), in Hilbert space, where the left vector is a bra and the right is a ket. Symbolised by ⟨...|...〉 (bra and ket only) or ⟨...|...|...〉 (bra, operator, ket).

日本語の意味

量子力学において、ハイルベルト空間内の状態を表すために使用される記法で、左側のベクトル（bra）と右側のベクトル（ket）の組み合わせ（またはbraとketの間に演算子を配置する場合もある）を指す。

In advanced quantum mechanics, the bra-ket denotes the inner product between a bra and a ket and is commonly written as ⟨φ|ψ⟩.

高度な量子力学では、ブラ・ケットは左側のブラと右側のケットとの内積を表し、通常は⟨φ|ψ⟩と表記されます。
