Abstract

The invention discloses an all-optical fiber quantum state simulation device. According to the device, a random wave signal generator is used to simulate the intrinsic properties of part of quantum states, and a traditional discrete element is replaced with an all-optical fiber interferometer, so that simulation and display of the all-optical fiber quantum states are realized. The device utilizesthe interferometer to generate random phase noise modulation, so that the device not only can simulate various quantum states but also can simulate various non-classical special states such as cross-phase modulation and the like, and simulation operation is convenient and easy. The invention further discloses an all-optical fiber quantum state simulation method based on the device. Non-quantum classical modulation and interference means are used for the first time to realize intrinsic property simulation and demonstration of the quantum states, so that the difficulty and cost of quantum technology learning and application are greatly reduced. The device has the easy integration characteristic of an all-optical fiber system, has the high stability and the efficient repeatability, and is anexcellent tool and means for quantum state simulation demonstration and learning.

Description

technical field [0001] The invention relates to a classical method for simulating a quantum state, in particular to an all-fiber quantum state simulating device and a simulating method. Background technique [0002] With the completion of the mission of the Micius satellite, the world has entered the era of quantum supremacy. Quantum technologies and equipment such as quantum computers, quantum simulations, and quantum communications have begun to emerge, and quantum technologies are gradually becoming popular and applied. More and more quantum phenomena have been discovered, and more and more quantum technologies have been applied. How to keep up with the trend of the times and participate in the quantum hegemony has become the focus of everyone. [0003] However, the principles of quantum mechanics are obscure and difficult to understand, and most people cannot enter the door. How to quickly learn and master the basis of quantum physics, deepen the understanding of quant...
