The notion of wave–particle duality remains one of the most debated subjects in the history of quantum physics. The most famous debate on the subject occurred between Bohr and Einstein. In this work, we revisit the wave–particle duality in the Bohr–Einstein debate from the viewpoint of the recently established duality-entanglement relation. We show that the duality-entanglement relation can provide a valuable framework for quantitative analysis of the Einstein's gedanken double-slit experiment and clarify some of its fundamental aspects.

In the study of quantum remote sensing, quantum spectral imaging. Since the beginning of 2001, after three stages of basic theory, scientific experiment and key technology research, has made breakthrough progress and innovative results. With the deepening of the research work and needs, some basic theoretical issues and cutting-edge technical problems need to be explored and studied. This paper discusses wave-particle duality of light is one of the important content. In more than and 100 years, wave-particle duality of light as research has made important progress. But the wave-particle duality of light is like what? Wave-particle duality of light like mechanism is what? Has been the most intense debate on the issue of Optics and physicists. In this paper, the author firstly summarizes the wave-particle duality of light development history and present situation of the research study, describes the research ideas of wave-particle duality of light; on this basis, the author puts forward the application of lightstring concept focuses on the wave-particle duality of light phenomenological characteristic geometry shape and movement of the content; describes the wave-particle duality of light like generated string-light effect mechanism. To study the wave-particle duality of light like two, a profound understanding of wave-particle duality of light nature, put forward a new research method.

Wave-particle duality lies at the root of quantum mechanics and is central in the description of interferences observed with elementary objects. In a delayed-choice experiment, the decision to observe the particle or wave character of a quantum system is delayed with respect to the time at which the system enters the interferometer. This paper reviews the history of the delayed-choice idea, introduced as a challenge to a realistic explanation of the wave-particle duality. It also describes recent experimental realizations of this idea and discusses intriguing extensions, such as the duality between separability and entanglement in multiple quantum systems.
