Teleportation without shared entanglement

Posted in: News

From ACQAO through The Quantum Pontiff: “Theorists from the UQ (Ashton Bradley, Simon Haine, Murray Olsen) and ANU Faculties (Joseph Hope) nodes of the ARC Centre of Excellence for Quantum-Atom Optics (ACQAO) have come up with a scheme to teleport quantum states of collections of atoms from one position to another by converting the quantum state to light and back again. The scheme relies on the sender and receiver each having a reservoir of extremely cold atoms, known as a Bose-Einstein condensate [and] it gets around the need for the sender and receiver to share entanglement, as the quantum state to be teleported is never actually measured“.1
