The algorithm was discovered/invented by analogy to Quantum Mechanics (with which it shares many similarities, but also important differences: the algorithm deals with probabilities, while the actual quantum physics deals with amplitudes, of which probabilities are the square).
Most of the stuff on that repository dates back about a year, and I first read about it about then here on Hacker News, but searching for the actual article has me swamped with references to quantum mechanics and physics.
Anyway, it has very general and broad applications indeed. Audio, 3D voxel spaces, et cetera, beyond the obvious 2D pixel space.
