Next-gen quantum teleportation in just 2 photons

Quantum teleportation just got simpler and more reliable. The enhanced technique could lead to secure quantum networks for communication and computing.

Despite its sci-fi connotation, quantum teleportation doesn’t magically move objects but instead transmits fragile information. Unlike classical data — the 1s and 0s used in electronics — quantum information can exist in multiple states at once, as long as the particles encoding the data are not disturbed or measured. Teleportation allows for the transfer of a particle’s quantum state from one particle to another.
