Optical quantum entanglement system is one of the most important systems for quantum information processing. The inevitable coupling between the entangled system and quantum noise will lead to the failure of the quantum information processing. Therefore, it is very important to investigate the effect of quantum noise on the entangled system and obtain the corresponding experimental laws. The properties and physical operator representation of optical typical quantum noise are given theoretically. In the experiment, various typical optical quantum noises are successfully simulated by using different optical devices or combination of devices. Taking the quantum bit flip noise as an example, the effect of noise on two qubit entanglement system is studied. Results show that for two qubit entangled systems, when the entanglement degree of the entanglement source is the same, the bit-flip noise is more likely to destroy the entanglement coherence than the phase-shift noise, and the ability of bit-phase-flip noise to destroy the entanglement property is between the former two.
