- Jan Sperling et al., Wave-particle duality revisited: Neither wave nor particle, arXiv:1907.09836
we derive correlation-based criteria that have to be satisfied when either particles or waves are fed into our interferometer. Using squeezed light, it is then confirmed that measured correlations are incompatible with either picture. Thus, within one single experiment, it is proven that neither a wave nor a particle model explains the observed phenomena.
What's new is that they give experimentally verifiable criteria for waveness and particleness, and test a situation where both fail.vanhees71 said:but what's new?
we have shown in theory and experiment that, already for relatively simple instances of quantum-optical setups, a particle and wave interpretation of quantum light simultaneously fails to explain the measured data.
Not of all QED but a strong case on the nonclassical part(Full QED)--(photon) counting statistics, fundamental/quantum limited noise, Reduced quantum uncertainty or experiments specifically looking at the physics of nonclassical light. Although the semiclassical version works very well--classic EM field in such major field in physics, which is an extremely powerful, yet classical device, that allows you to do all sorts of quantum experiments.vanhees71 said:The upshot seems to be: There's neither waves nor particles and no wave-particle duality but only QED describing all findings in quantum optics.
Wave-particle duality is a concept in quantum mechanics that describes the behavior of particles as both waves and particles. This means that particles can exhibit characteristics of both waves and particles depending on how they are observed.
The concept of wave-particle duality was first discovered by scientists studying the behavior of light in the late 19th century. They found that light exhibited properties of both waves and particles, leading to the development of quantum mechanics.
This phrase refers to the idea that particles do not have a fixed nature and can exist as both waves and particles simultaneously. It challenges the traditional understanding of particles as either one or the other, and suggests that they are more complex and multifaceted than previously thought.
Wave-particle duality has led to a deeper understanding of the fundamental nature of matter and energy. It has also played a crucial role in the development of quantum mechanics and has allowed scientists to make advancements in fields such as technology, medicine, and materials science.
Yes, there are several practical applications of wave-particle duality, including the development of quantum computers, which use the principles of quantum mechanics to perform calculations at a much faster rate than traditional computers. It has also been used in medical imaging techniques, such as MRI, and in the development of new materials with unique properties.
