A new type of binary elementary logic circuit will be presented: the random flip-flop (RFF). Unlike conventional Boolean logic circuits whose action is intentionally made deterministic and highly reproducible, action of the RFF is intentionally random and, in the proposed realization, derived from the fundamentally random quantum process of emission and detection of light. By definition, RFF operates as a conventional flip-flop except that its clock input functions with probability of 1/2 otherwise it does nothing. Seemingly simple, this circuit features surprising richness of possible applications both analog and digital, including: random number generation, cryptography, spurious-free frequency synthesis, white noise generation, randomness preserving frequency division, random frequency synthesis, over-Turing computing and bio-inspired massively parallel computing. RFF has been realized in a hybrid technique and some of the first experimental results will be presented. A possibility and advantages of realizing quantum RFF on a chip will be discussed.
