TechnologyUltracold atoms have been 'hyperentangled' for the first time By exerting unprecedented control over extremely cold atoms, researchers have put them in a state with several simultaneously quantum-entangled properties 51¶¯Âþ
PhysicsWhere exactly does the quantum world end and concrete reality begin? Quantum effects like superposition and entanglement have long been seen in single particles, but physicists are on a quest to find out just how big an object can be before it loses its quantumness Features
