Scientists teleport quantum information across the room
By Colin Jeffrey
Researchers working at TU Delft’s Kavli Institute of Nanoscience in the Netherlands claim to have successfully transferred data via teleportation. By exploiting the quantum phenomenon known as particle entanglement, the team says it transferred information across a 3 m (10 ft) distance, without the information actually travelling through the intervening space.
In this case, the team teleported information contained in one quantum bit (or qubit, the quantum analog of a standard computer bit) to a completely separate quantum bit, using specially-designed computer chips. Each chip featured a synthetic diamond to contain the entangled electrons and several nitrogen atoms. Data was then encoded for transmission in the transmitting diamond’s nitrogen atom as alterations of the spin of the electron. The electron in the receiver diamond then showed the opposite of that manipulation at precisely the time that the transmission was “sent.”
In future experiments, the TU Delft team is planning on increasing the distance to more than 1,300 m (4,200 ft) with chips housed in several buildings across the university campus. The researchers hope to be the first to realize evidence to disprove Einstein’s rejection of the entanglement theory.
