This is for producing quantum state vectors in bra–ket notation, using wikicode, ideally with {{math}}, as an alternative to LaTeX in <math> mode.

This template uses {{braket}}.

Application

There is one parameter, which is the text to be displayed as the ket label.

A ket can be written: |Ψ⟩, that is {{ket|Ψ}}.

Using {{math}}, a ket can be written: $|Ψ ⟩$ , that is {{math|{{ket|Ψ}}}}.

In wiki-markup rather than LaTeX:

iħ.mw-parser-output .sfrac{white-space:nowrap}.mw-parser-output .sfrac.tion,.mw-parser-output .sfrac .tion{display:inline-block;vertical-align:-0.5em;font-size:85%;text-align:center}.mw-parser-output .sfrac .num,.mw-parser-output .sfrac .den{display:block;line-height:1em;margin:0 0.1em}.mw-parser-output .sfrac .den{border-top:1px solid}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}d/dt|ψ(t)⟩ = Ĥ|ψ(t)⟩

that is,

{{math|1=''iħ''{{sfrac|''d''|''dt''}}{{ket|''ψ''(''t'')}} = ''Ĥ''{{ket|''ψ''(''t'')}}}}
