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…

A new piece of the quantum computing puzzle

An efficient two-bit quantum logic gate has been out of reach, until now

When a single photon enters a logic gate, nothing notable happens — it goes in and comes out. But when there are two pho…
