A whopping 100,000 entangled photons have been detected for the first time, beating the previous record of just 12, New Scientist reports.
The technique could be useful for safely sharing keys used in encrypted communications.
Entangled photons have linked quantum states, such that measuring the state of one photon determines the state of the others, no matter how far apart they are.
Detecting entanglement usually… read more
