ENTANGLEMENT AND INFORMATION TRANSFER PROTOCOL BETWEEN TWO QUBITS

Abstract

Based on the general unitary operations of two-qubit system, we investigate the dynamics of information swapping between two qubits. We briefly describe the general behavior of entanglement entropy and the purity taking into account two classes of initially states, either product state or entangled state. Using the phenomenon of information swapping, we suggest a theoretical protocol to transform the coded information from sender to the receiver.
