Examples

Many phenomena that are explained using quantum mechanics are usually most clearly demonstrated with the help of the bra-ket notation. Source: Internet

Properties bra-ket notation was designed to facilitate the formal manipulation of linear-algebraic expressions. Source: Internet

Since virtually every calculation in quantum mechanics involves vectors and linear operators, it can involve, and often does involve, bra-ket notation. Source: Internet

The bra-ket notation continues to work in an analogous way in this broader context. Source: Internet

This is known as Dirac notation or bra-ket notation. Source: Internet
