Physicists have carried out successful teleportation with particles of light over a distance of 600m across the River Danube in Austria.
Long distance teleportation is crucial if dreams of superfast quantum computing are to be realised.

Researchers from the University of Vienna and the Austrian Academy of Science used an 800m-long optical fibre fed through a public sewer system tunnel to connect labs on opposite sides of the River Danube.

The link establishes a channel between the labs, dubbed Alice and Bob. This enables the properties, or "quantum states", of light particles to be transferred between the sender (Alice) and the receiver (Bob).

The Austrian team encoded their qubits using a property of light particles, also called photons, known as polarisation. This property describes the direction in which they oscillate.

And so on and so on.

The real question is, should we try to stop them now or after they try to bring back Hitler?
