TURKU, Finland — Beam me up, Scotty! In a study that seems straight out of a “Star Trek” episode, an international team of researchers has achieved a remarkable feat in the realm of quantum teleportation. They have successfully conducted near-perfect quantum teleportation despite the presence of noise that typically disrupts the transfer of quantum states.
Quantum teleportation is a process in which the state of a quantum particle, or qubit, is transferred from one location to another without physically sending the particle itself. This transfer requires quantum resources, such as entanglement between an additional pair of qubits.
They transferred the qubits but using it (and knowing when you can use it) still requires non causality breaking methods.
Things like this are more useful for secure transfer of data without eavesdropping. You send qubits of data at a set time, etc and then send a message at non FTL speeds to say “it’s ready… read it” and they can do so.
