So I know nothing about probabilistic computing, but is my intuition about how these work correct? Essentially, a qubit can have a superposition over 0 and 1 and operations upon that qubit will change the probability and then when you "pop it" to read it out you will get the output that you want depending on the program that you set up. By contrast, this "pbit" works by having some probability between 0 and 1 and this is represented by something, for example a time varying flicker between 0 and 1 which is weighted by the same aforementioned probability. Then, operations upon the pbit can change the probability depending upon the program and you read it out by sampling to see what the output of it is supposed to be. If so, wouldn't it suffer from the Monte Carlo integration issue? Namely, in theory it is nearly independent of the number of dimensions, but in practice as your number of dimensions (here the number of bits, pbits or qubits) goes up you will get worse results?
