Idea

A quantum programming language is a programming language for quantum computation.

In as far as data types in classical programming languages may and often are understood in terms of (dependent) type theory, quantum programming languages concern quantum data types such as “qbits” which may be understood via linear logic (Pratt (1992)) in (dependent) linear type theory (e.g. Abramsky & Duncan (2005); Duncan (2006); Dal Lago & Faggian (2012); Green et al (2013); Staton (2015)):

“A quantum programming language captures the ideas of quantum computation in a linear type theory.” [Staton (2015), p. 1]

Many existing quantum programming languages are in fact domain specific programming languages for the description of quantum circuits compiled from quantum logic gates, and as such often embedded into ambient type theories (eg. Quipper and QWIRE).

Other QPLs are more algorithmic (such as Q Sharp).

Quantum programming languages

The first proposal towards formalizing quantum programming languages was:

and early formalization via quantum lambda-calculus invoking linear logic/linear types (cf. Pratt 1992 etc.):

[Selinger (2016):] When the QPL workshop series was first founded, it was called “Quantum Programming Languages”. One year I wasn’t participating, and while I wasn’t looking they changed the name to “Quantum Physics and Logic” — same acronym!

Back in those days in the early 21st century we were actually trying to do programming languages for quantum computing [[Selinger & Valiron 2004]], but the sad thing is: In those days nobody really cared. [...][...]

Now it’s 15 years later and several of these parameters have changed: There has been a renewed interest, from government agencies and also from companies who are actually building quantum computers. [...][...].

So now people are working on quantum programming languages again.
