Properties of quantum bit in quantum ring;

The properties of quantum bit (Qubit) and quantum logic gates (quantum not-gate, Hadamard gate, quantum controlled not-gate, Toffoli gate etc.

A new improved quantum-inspired genetic algorithm(IQGA)based approach to optimize power system reactive power is proposed,in which several conception in quantum calculation are used for reference and the quantum bit is used in the coding of control variables,such coding mode can represent many possible linear superposition states,thus the population diversity can be maintained better.

Versatility in quantum error correcting code of encodingone qubit in five qubits;

Influence of the Phonon Effect on the Quality Factors of Free Rotation of Qubit;

Remote transmission of n-qubit quantum information without direct Bell-State-Measurement-free;

Design of the scalable quantum comparator;

The theoretical models based on an ideal single-photon source and a single-photon source with Poisson distribution are established by introducing the measuring factor and the shifting factor,and the expressions of quantum bit rate are given.
