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 News
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
