Fundamental Advance in Quantum Computer Languages

A news clip from “The Register” (a British newspaper):

U.K.- Some boffins from Oxford University have just published a paper in Nature magazine describing a new quantum computer programming language called QubitPOX (Qubit Programming at Oxford). Academic experts in the field unanimously agree that this new language represents a tremendous improvement over simple quantum circuits because it uses deep principles from Category Theory. In the new language, a CNOT is represented by the elegant statement:


Even better, the totally opaque quantum circuit for a 2-qubit quantum Fourier transform is denoted by the beautifully intuitive statement:

Heretofore, those who wanted to learn how to program a quantum computer using the old fuddy duddy method of quantum circuits were faced with a very steep learning curve. QubitPOX promises to change all that. According to Oxford Prof. Bob Coecke, the only prerequisites for understanding it are kindergarten level maths. Here is an introduction to it in pdf format (just 1099 pages).

Simon Gay, an authority in the quantum field, said “We are as pleased as Punch with our new language. Hip, hip, hooray for Oxford!”.
