As the essential tool of quantum information technology, there are the quantum-state preparation, the quantum-state control, and quantum measurement. These methods with high precision are needed to implement quantum computation, quantum communication, or quantum cryptography. Furthermore, the linear and quantum optics has developed compared to other physical systems. Under this situation, to pursue the aim to construct quantum measurement implemented by light, we have studied quantum measurement with optical vortex beam. In this presentation, we would like to show our recent results and these applications in quantum technology.
