Researchers from the University of Bristol and Université Libre de Bruxelles have theoretically shown how to write programs for random circuitry in quantum computers.

The breakthrough, published in the New Journal of Physics, is based on the work of first author, Dr Nick Russell, who tragically lost his life in a climbing accident last year.

"One of the many applications for random quantum circuits is the realisation of a rudimentary version of a quantum computer, known as a "boson sampler". A boson sampler could be among an early class of quantum technologies that prove their intrinsic superiority over classical machines. Such a demonstration would be a landmark in the history of science," said Dr Anthony Laing from the University of Bristol's School of Physics, who supervised Dr Russell's thesis.
