London, Dec 8 : Taking a major step towards creation of quantum networks, physicists at the Georgia Institute of Technology have made a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms.
Although the information remains usable for just milliseconds, even that short lifetime should be enough to allow transmission of data from one quantum repeater to another on an optical network.
The new record is of 7 milliseconds for rubidium atoms stored in a dipole optical trap, while the previous record for storage time was 32 microseconds- a difference of more than two orders of magnitude.
