报告题目： Experimental investigation of quantum information based on optical field modulation
Optical field modulation can be generally subdivided into spatial domain and time domain modulation. Spatial domain includes amplitude, phase, polarization and spatial distribution and so on. Time domain includes laser pulse shape, pulse width, chirp and coherence characteristics. Recently, our work focus on orbital angular momentum in the spatial domain, and frequency modulation in the time domain. By using the optical field modulation technology, we have done some interesting work include the single system steering, dimension witness and the full control dephasing dynamics.
