System and method for quantum based information transfer

Abstract

A system for communicating data comprising sender and receiver subsystems; at least one data input; at least one entangled photon source; first photons of the pairs of entangled photons outputted by the at least one photon source being processed by one of the sender or receiver subsystem; second photons of the pairs of entangled photons being processed by the other of the sender or receiver subsystem; a photonic element configured to receive the first photons of the pairs of entangled photons and enable interference therebetween; at least one absorber configured to absorb the first photons after passage through the beam splitter, the absorbance of the first photons operating to transfer the properties of the entanglement to the second photons of the pairs of entangled photons; and a Bell state measurement element operatively associated with the receiver subsystem configured to measure the second photons of the pairs of entangled photons.

AI Technical Summary

Benefits of technology

The present invention is a system for communicating data using entangled photons. The system includes a sender subsystem and a receiver subsystem. The sender subsystem processes the data and sends it to the receiver subsystem using entangled photons. The receiver subsystem measures the entanglement of the photons and sends the information to a data source or an output measurement element. The system can also include an interrupt to prevent the transmission of certain messages. The invention provides a method for transferring information using entangled photons and ensures that the properties of the entanglement are preserved during transmission.

Problems solved by technology

These optical fields 1 and 2 interfere on a Beam Splitter BS resulting in L and R atomic ensembles becoming entangled.
