The inner product on Hilbert space ( , ) (with the first argument anti linear as preferred by physicists) is fully equivalent to an (anti-linear) identification between the space of kets and that of bras in the bra ket notation: for a vector ket = | define a functional (i.e. bra) = | by
This is for a producing inner products of quantum states in bra–ket notation, using wikicode, ideally with {}, as an alternative to LaTeX in <math> mode. This template uses {{ braket }} . Application
ket (for a ket vector), bra-ket (for the inner product), or; Symbol 1: if 1 is set to bra or ket: enter the first symbol for the bra or ket, if 1 is set to bra-ket: enter the symbol for the bra part of the inner product; Symbol 2: if 1 is set to bra or ket: this parameter is not needed.
In mathematics, an inner product space (or, rarely, a Hausdorff pre-Hilbert space [1] [2]) is a real vector space or a complex vector space with an operation called an inner product. The inner product of two vectors in the space is a scalar, often denoted with angle brackets such as in , .
The inner product of two vectors is commonly written as ... In quantum mechanics, angle brackets are also used as part of Dirac's formalism, bra–ket notation, ...

In his above-mentioned account, he introduced the bra–ket notation, together with an abstract formulation in terms of the Hilbert space used in functional analysis; he showed that Schrödinger's and Heisenberg's approaches were two different representations of the same theory, and found a third, most general one, which represented the ...
Synonymous to "bra–ket notation". Hilbert space Given a system, the possible pure state can be represented as a vector in a Hilbert space. Each ray (vectors differ by phase and magnitude only) in the corresponding Hilbert space represent a state. [nb 1] Ket A wave function expressed in the form | is called a ket. See "bra–ket notation".
