It's much colder than that, single-digit millikelvin. They use He-3/4 dilution refrigerators [1]. Getting things cold and electromagnetically-quiet enough that the quantum state doesn't collapse is a big challenge in the field.

And if you need colder than 2mk, nuclear demagnetization:

And some people think the brain can be deterministic at 300K.

Why not? Computers are deterministic at higher temperatures.

Even assuming a computer model, think of an analog computer with long integration times, potentially high gain for thermal noise terms, simulating a chaotic system.

Or, look at literature on error rates for people performing simple repetitive tasks.
