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 t
