Abstract

The invention provides a quantum imaging method and a quantum imaging system and belongs to the technical field of quantum imaging. The method and the system solve the problem that the existing quantum imaging method is poor in imaging effect in the prior art. The quantum imaging method comprises the following steps of generating two beams of chaotic lasers, dividing the two beams of chaotic lasers into a first signal light and a second signal light, illuminating an object by using the first signal light, correlating the first signal light with the second signal light after the object is illuminated by the first signal light so as to obtain a correlation result, obtaining the phase information of the object according to the correlation result, and obtaining the image of the object according to the phase information of the object.

Description

technical field [0001] The invention belongs to the technical field of quantum imaging, and in particular relates to a quantum imaging method and a quantum imaging system. Background technique [0002] Quantum optics is a very rapidly developing field attracting a lot of attention. On the one hand, people use some light quantum states to realize the processing of various quantum information such as quantum teleportation, quantum keys, quantum computing, and quantum precision measurement; on the other hand, the Heisenberg uncertainty relation in quantum mechanics determines There is a limit in any measurement: Standard quantum limit (SNL), also known as shot noise limit (Shot noise limit, SNL). In addition to the standard quantum limit, there exists a higher Heisenberg limit (HL). Conventional measurement techniques do not reach this limit, only close to the standard quantum limit. [0003] Quantum imaging is an important branch of quantum optics, which is the problem of s...
