Elegant quantum teleportation with only one single photon

Scientists at MPQ succeed for the first time in teleporting quantum information encoded in an atomic qubit to a laboratory 60 meters away using just one single photon as a resource.

Quantum teleportation therefore does not transfer matter – the atoms remain in their place – but only their stored infor…
