(Phys.org) -- A European team of physicists has bested the record set by a team of Chinese researchers last month for distance in teleporting quantum bits (qubits). Where the Chinese team accomplished their feat by teleporting ...
(Phys.org) -- A team of Chinese physicists has broken the distance record for teleporting qubits, extending it from 16 to 97 kilometers. They did so, as they explain in their paper uploaded to the preprint server arXiv, using ...
The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton Zeilinger at the ...
