‘Beam me up, data!’
Teleporting people through space, as is done in Star Trek, is impossible by the laws of physics. Teleporting information is another matter, however, thanks to the extraordinary world of quantum mechanics. Researchers at TU Delft’s Kavli Institute of Nanoscience have succeeded in deterministically transferring the information contained in a quantum bit – the quantum analogue of a classical bit – to a different quantum bit 3 metres away, without the information having travelled through the intervening space: teleportation. The results are published online in Science, on Thursday 29 May.

high resolution: sample with spin teleporter
This image is an electron microscope picture of one of the two devices, with a fictitious teleportation beam added. The image is about 40 micrometer wide in reality.
high resolution: setup bright, setup dark
This image shows the experimental setup used to teleport the state of a spin between two distant diamonds. The diamonds are hosted in two low-temperature microscopes, that can be seen on the far corners of the table.
A forest of optical elements to guide single photons from- and laser beams to each diamond.
high resolution: chip with diamond, zoom in of diamond
(left) This image shows one of the two chips used in the teleportation experiment. The diamond can be seen wired up exactly in the centre of the image. (right) Zoom in of the diamond chip: under each dome there is a small register of quantum bits.
high resolution: teleportation between two diamonds
Artistic impression of quantum teleportation of a spin state between two distant diamonds.
This animation shows schematically how to teleport the state of a spin between two distant locations.
In the short video below, Ronald Hanson explains several aspects of quantum teleportation, including a description of the experiment and the consequences of the expected results (at the time of filming the teleportation experiment was not yet performed).

Two years ago we made a short movie to explain part of our experiment for a general audience, to compete in the FOM short movie challenge. We were one of three prize-winners! You can see our submission below:
