One Step Closer to Teleportation
Scientists at the Joint Quantum Institute at the University of Maryland have made progress towards making teleportation a reality. A recent experiment has successfully transferred quantum information intact from one atom to another over the distance of about a meter. Now, this isn’t quite the feat of transferring a human from place to place, but the success of having this atom level information jump from one place to another indicates that more robust forms of teleportation may be possible.
Live Science explains:
Teleportation is one of nature’s most mysterious forms of transport: Quantum information, such as the spin of a particle or the polarization of a photon, is transferred from one place to another, without traveling through any physical medium. It has previously been achieved between photons (a unit, or quantum, of electromagnetic radiation, such as light) over very large distances, between photons and ensembles of atoms, and between two nearby atoms through the intermediary action of a third.
None of those, however, provides a feasible means of holding and managing quantum information over long distances.
Now the JQI team, along with colleagues at the University of Michigan, has succeeded in teleporting a quantum state directly from one atom to another over a meter. That capability is necessary for workable quantum information systems because they will require memory storage at both the sending and receiving ends of the transmission.
