New quantum discovery could lead to secure post-quantum communication

New research on quantum entanglement, conducted by Heriot-Watt University in the UK and the University of Geneva in Switzerland, could help deliver communication networks difficult to target in the post-quantum era. Researchers found a way for quantum entanglement to handle noise and loss over long distances, opening the door to ‘practical quantum networks with the highest form of security’.

Quantum entanglement is when two particles – such as photons – remain connected and operate in tandem, even when they are separated over a vast distance. The research claims that this could provide the potential for truly secure communications in the future, even if a communication device is unsafe or in criminal hands.
