Quantum realism is a term I first learned from an article by Brian Whitworth, a senior lecturer in computing at Massey University. The idea is in opposition to “physical realism” (that belief that the physical world we see is real and exists by itself, alone). Quantum realism asserts that the physical world isn’t real in itself, but merely the output (or shadow, or result, or projected image) of a quantum reality that is generating it. It’s basically a virtual reality, or a simulation.
I’m still learning about this and definitely couldn’t explain or defend it, but I’m fascinated by the idea and keep thinking about it. I need to read this a few more times.
