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 q-bits that are delicate quantum superpositions of 0 and 1.
Intermediate between a bit and a q-bit, is a probabilistic bit or a p-bit that are robust classical entities fluctuating randomly between 0 and 1.
How could we implement p-bits and what could we do with them?
Below is a 10-minute introduction by Supriyo Datta.
