However, the biggest hurdle is that photons don’t like interacting with each other, which makes the critical two-qubit gates difficult to create. But a 2001 discovery showed it was in fact possible to effectively make two-qubit interactions and therefore a full quantum computer solely with linear optical elements, single photon sources and detectors. This discovery catalysed a wealth of research into optical quantum computers which in aggregate has today made it a viable contender to a path to scalable fault tolerant quantum computers. The scheme that opened the floodgates for optical quantum computers is referred to as the KLM protocol after its originators Knill, Laflamme, and Milburn.
