‘Unbreakable’ quantum communication closer to reality thanks to new, exceptionally bright photons

Scientists have created an “exceptionally bright” light source that can generate quantum-entangled photons (particles of light) which could be used to securely transmit data in a future high-speed quantum communications network.

A future quantum internet could transmit information using pairs of entangled photons — meaning the particles share information over time and space regardless of distance. Based on the weird laws of quantum mechanics, information encoded into these entangled photons can be transferred at high speeds while their “quantum coherence” — a state in which the particles are entangled — ensures the data cannot be intercepted.
