TechnologyQuantum computers are on track to solve knotty mathematical problems A quantum algorithm for solving mathematical problems related to knots could give us the first example of a quantum computer tackling a genuinely useful problem that would otherwise be impossible for a classical computer ¿ìè¶ÌÊÓÆµ
PhysicsQuantum disorder is dependent on who is looking for it A new understanding of how an observer can change the disorder, or entropy, of a quantum object could help us probe how gravity interacts with the quantum realm ¿ìè¶ÌÊÓÆµ
