Abstract
The disclosure discloses an OAM measurement device independent quantum key distribution system based on real-time tracking compensation and method thereof, which comprises a user side Alice, a user side Bob and a measuring unit; the user side Alice and the user side Bob realize real-time monitoring and phase distortion compensation of the channel environment by using strong pulse lasers from the measuring unit; the measuring unit utilizes an M-Z interferometer formed by a Dove prism to realize the separation of odd/even orbital angular momentum order photons, and measure Bell states of the photons with orbital angular momentum; the disclosure realizes OAM measurement device independent quantum key distribution system based on real-time tracking compensation, and the user uses the orbital angular momentum state for coding, thereby having the characteristics of good stability, high code rate and strong expansibility.
