Hi, after reading this article, I was left wondering how the heck a quantum computer can be simulated. To begin with, how is a quantum computer of 42 qubits built up? And the how could this computer possibly be simulated? I mean, the wave function of one qubit is a three dimensional scalar field, so 42 bits would be... a 3x42 = 126 dimensional scalar field?? That they have made a PDE out from which they are solving? Or have they succeeded to make a 242 (only) variable ODE by considering the spins of the electrons only? Then if there is this 242 (~ 4.4 trillion) variable ODE, what does it look like? How does each of these states of the system behave, and can two states affect each other?
