Patent image
CCDC ARL

A method and system for transferring data comprising: an entangled photon source for producing first and second entangled photons associated with a receiver and a sender, respectively;a Bell state measurement device for performing a joint Bell state measurement on the second entangled photon and the at least one qubit; the Bell state measurement device outputting two bits of data to be used at the receiver;a transmission channel for transmitting two bits from the outcome of the Bell state measurement device to the receiver;a unitary transformation device for performing a unitary transformation operation on the first entangled photon based upon the value of the two bits of data;at least one detector for detecting encoded information from the first entangled photon; at least one processor operating to determine whether or not to transmit portions of data from a sequential successive qubit based upon the preceding qubit.
