This test shattered the same team's previous record and may herald the development of greater, long-distance teleportation techniques and qubit communications and computing capabilities.

The experiment involved generating a quantum entanglement of two photons via a laser, then sending one of those entangled photons down an optical fiber whilst simultaneously sending the other to a crystal (composed of yttrium orthosilicate), where it was stored. A third photon was then sent to hit the first photon in the optical fiber, obliterating both itself and the first photon.

The researchers then used a device to measure the results of this collision and discovered that the quantum state information contained in the third photon was not actually destroyed, but had made its way into the crystal where the second entangled photon was contained.
