The Road to Quantum Teleportation

  In the November study, the researchers successfully “beamed” polarization between a photon pair, and they could do this because the particles were entangled.

  Equating quantum (information) teleportation with physical teleportation of objects really just reveals that the author has no idea what they’re talking about.

    Sadly very typical for science journalists.

    But is quantum Tele even useful

      At the moment it’s experimental, so no.

      And just to be clear, this cannot be used to move information faster than the speed of light, ever.

      In theory it might have application as a sort of tamper-evident seal for digital encryption.

      If you have a very noisy quantum communication channel, you can combine a second algorithm called quantum distillation with quantum teleportation to effectively bypass the quantum communication channel and send a qubit over a classical communication channel. That is the main utility I see for it. Basically, very useful for transmitting qubits over a noisy quantum network.

  Sans paywall.
