Regular old quantum teleportation wasn’t enough for scientists. So they’ve kicked it up a notch.
Previously, physicists had teleported qubits, or quantum bits of information. Just as a standard bit in a desktop computer has two possible values, 0 or 1, a qubit has two possible states. Now scientists have moved on, reporting in the Aug. 16 Physical Review Letters that they’ve teleported qutrits, which have three possible states. Both qubits and qutrits have the weird quantum property of being able to exist in multiple states at once. But while a qubit can represent 0 and 1 at the same time, a qutrit can be a combination of 0, 1 and 2.
