Next-gen quantum teleportation in just 2 photons

Information transmitted between two particles instead of standard three

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 t...
