TechnologyQuantum supremacy has been achieved by a more complex quantum computer A quantum computer made by researchers in China has outperformed classical computers, achieving what is known as quantum supremacy with a more complex quantum processor than ever before News
PhysicsWhat putting big things in quantum states can tell us about reality In principle, there should be no limit on how large objects can get and still display quantum behaviour like superpositions. Physicists testing the idea hope to reveal clues about quantum gravity Features
