“Quantum ignorance” might sound like a joke, like something a non-scientist might say to show they know nothing whatsoever about quantum mechanics. Well, here’s the punchline; “quantum ignorance” is a real thing in quantum mechanics. Even better, I’ll explain why researchers from The University of California at Davis (USA) are genuinely worried about it. Indeed, everyone should be worried about what’d going on in the field as it has consequences for every day things such as flipping a coin or winning a bet.
The discussion starts with a reminder of the uses of probability. Probability as we use it everyday is known as “classical” probability because it makes sense to us on an everyday level. There are other kinds of probability – quantum mechanics uses its own version of probability which behaves differently and is arguably the cause of all the oddness which we associate with quantum mechanics.
In classical probability, we…
