A new study shows that one of quantum mechanics’ strangest properties may be the secret ingredient that makes powerful quantum computers possible. According to research by physicists at A*STAR and the National University of Singapore (NUS), this property, known as contextuality, plays a central role in error-correcting codes – the mathematical tools that protect quantum information from noise. The finding suggests that quantum weirdness is not just an exotic curiosity. Instead, it’s baked into the very structure of the codes that keep quantum computers alive.
