The quantum web might be coming to you through drone.

Researchers have now used drones to transmit particles of light, or photons, that share the quantum linkage called entanglement. The photons were sent out to 2 places a kilometer apart, scientists from Nanjing University in China report in a research study to appear in Physical Review Letters

Entangled quantum particles can maintain their interconnected properties even when separated by long distances. Such counterproductive behavior can be harnessed to allow brand-new types of communication. Eventually, scientists intend to construct a global quantum internet that counts on transferring quantum particles to enable ultrasecure interactions by utilizing the particles to produce secret codes to secure messages. A quantum web could likewise permit far-off quantum computers to interact, or perform experiments that check the limits of quantum physics.

Quantum networks made with fiber-optic cables are already beginning to be utilized ( SN: 9/28/20). And a quantum satellite can transfer photons throughout China ( SN: 6/15/17).

The researchers used two drones to transfer the photons. One drone developed pairs of entangled particles, sending one particle to a station on the ground while passing on the other to the second drone. That maker then transmitted the particle it got to a second ground station a kilometer away from the. In the future, fleets of drones might work together to send knotted particles to receivers in a range of areas.
