Light goes through the atomic cloud in the center and falls onto the membrane on the left. Because of the interaction with light the precession of atomic spins and vibration of the membrane become quantum correlated. Credit: Niels Bohr Institute
Researchers accomplished quantum entanglement between a mechanical oscillator and a cloud of atoms.The feat promises application in quantum communication and quantum sensors.Quantum entanglement involves linking two objects, making them behave as one at a distance.
Scientists entangled two large quantum objects, both at different locations from each other, in a quantum mechanics first. The feat is a step towards practical application of a rather counterintuitive phenomenon and was accomplished by a team from the Niels Bohr Institute at the University of Copenhagen.Leer Más
