Control method of electronic apparatus authenticating output of classifier by using orthogonal input encoding

Abstract

An electronic apparatus, including: an input interface; and at least one processor configured to: receive bit-format input data using the input interface, convert input bits included in the input data to obtain input qubits, encode the input qubits to obtain encoded qubits, estimate quantum amplitude values of a predetermined number of the input qubits using a quantum neural network (QNN) based on the encoded qubits, determine a probability value corresponding to the data based on the estimated quantum amplitude values, and authenticate the input data by comparing the determined probability value with a predetermined authentication radius value
