Probabilistic bit

Probabilistic bit (P bit) is a pseudo-qubit that outputs 0 or 1 probabilistically. A superconducting random number generator was used as the output of the P bit. Magnetic coupling was used as the interaction. Simulation results showed that the desired P bit output could be obtained by controlling the positive/negative and magnitude of the interaction. This method has the potential to efficiently solve optimization and other problems using P bits.
