Digital electronics is based on stable bits that can have one of two values, 0 and 1. At the other extreme we have quantum computing using using q-bits that can be in superposition states that are 0 and 1 at the same time. In our recent work we have introduced a concept that is intermediate between bits and q-bits, namely a probabilistic bit or p-bit that fluctuates randomly between 0 and 1.
