Etymology 1

From bra-ket notation invented by Paul Dirac.

Noun

Wikipedia ket (plural kets)

1. (physics) A vector, in Hilbert space, especially as representing the state of a quantum mechanical system; the complex conjugate of a bra; a ket vector. Symbolised by |...〉.

   A particular ket, say $|A\rangle$, might be represented by a particular column vector. Its corresponding bra, $\langle A|$, would then be represented by the row vector which is the transpose conjugate of that column vector.

Etymology 2

Compare Icelandic kjöt (“flesh”); akin to Swedish kött and Danish kjöd. The use of the term ket for "candy" or "sweets" probably derived from its use to describe sweet meats or as a deterrent to children.

Noun

ket (plural kets)

1. (Northern England) Carrion; any filth.
2. (Northumbrian) Sweetmeats.
3. (Geordie) A sweet, treat or candy.
