I remember when this was announced last year; however, I am glad to see the topic highlighted again especially after China’s launch of their Quantum Satellite.
Quantum teleportation is the mystical, far-off in the future idea where quantum information encoded into particles of light can be transferred from one place to another remotely. Except it’s not far-off in the future — it just happened. Teleportation is real and it is here.
The teleportation occurred over several kilometres of optical fibre networks in the cities of Hefei in China and Calgary in Canada.
The two independent studies show that quantum teleportation across metropolitan networks is technologically feasible, and pave the way towards future city-scale quantum technologies and communications networks, such as a quantum internet.
