Irrational numbers, physics and quantum computing

[pmbug]

Quantum mechanics works perfectly in experiments, but Oxford physicist Tim Palmer argues it rests on a mathematical fiction: building the theory on the continuum of real numbers, including irrational numbers like √2. Palmer’s radical alternative abandons the continuum of real numbers and eliminates quantum mysteries that aren't actually physical—from Schrödinger's cat, to Einstein’s “spooky action at a distance.” The theory makes a testable prediction: quantum computers will fail beyond 400 qubits, hitting a fundamental limit set by the discrete structure of nature itself. The coming quantum computing race will determine whether Palmer has identified a basic mistake in our most successful theory.
