‘Quantum Darwinism’ may explain why we live in a shared reality

The quantum realm is notoriously full of uncertainties, but observers like us still manage to agree on how we experience it in very concrete ways. A quantum framework inspired by evolutionary principles may explain how such consensus is possible – and now researchers have proved it mathematically.

“Every day, when you go outside, you see things. And you see them as localised. You don’t see weird quantum features. So, the question is, how can we connect this divide between quantum and classical?” says Akram Touil at Los Alamos National…
