Measuring the quantum state of light
WebDec 22, 2024 · We show how the precise control of the electron before and after its interaction with quantum light enables to extract the photon statistics and implement full … WebThough the measurement precision of the traditional LiDAR is gradually increased, it is still limited by the quantum noise of the optical field and the extra noise introduced by the detection process. To improve the detection performance of LiDAR, a new scheme using quantum squeezed state light field as local oscillator of LiDAR was proposed and the key …
