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.
Imagine
an etch-a-sketcha Magna Doodle where you have the front side of the board and someone else has the back side. Every cell must be either black or white, and a cell in one state on your board must always be in the other state on the other board. Whatever you write on your side appears in the negative on the other. It’s like that, but quantum.
