Abstract

We present a simple and portable experimental setup that demonstrates the concept of wave–particle duality. Our setup is constructed by modifying the Thorlabs Quantum Optics Educational Kit and can be used in various educational contexts, ranging from general public demonstrations to classroom experiments both in wave optics and quantum mechanics lectures. We propose a set of experiments that provide a pedagogical progression in which basic quantum concepts are introduced systematically.

Maksim A. Skorobogatiy, Kshitij Kshitij

The main motivation for this paper is to provide a practical guide for the beginners in experimental quantum optics, to save the frustration and make the learning process more streamlined for the novices in the field. This work details the finer points of experiments in the fundamental quantum optics performed using Thorlab’s Quantum Optics Kit. Namely, we detail our observations, interpretations, and subtleties of functioning and arrangement of the experimental setups learned through hands-on experience.

Demonstration of Generalized Multi-path Wave-particle Duality on a Quantum Nanophotonic Chip

Xiaojiong Chen, Yaohao Deng, Shuheng Liu +15 more

The wave-particle duality of quantum objects has been a center concept in quantum mechanics since its birth. For the two-path or two-slit experiment, the dual nature of quantum matter has been well studied in various systems. To rule out the interpretation of quanta knowing the measurement setting it will be confronted, Wheeler proposed the famous delayed-choice gedanken experiment [1] , which is an ideal platform to test the intrinsic characters of wave-particle duality. However, all these experiments to date have been focused on the two-path case.

Development and application of a LabVIEW-based teaching tool for quantum mechanics: visualization of wave-particle duality

Gerui Ge, Yi-Heng Wu, Li Hua Zhang +2 more

Abstract Quantum mechanics, the cornerstone of modern physics, is often perceived as abstract and complex, particularly by beginners, with regard to the wave-particle duality of microscopic particles. Traditional teaching methods often fail to foster an intuitive understanding of these concepts among students. Consequently, the search for more effective, interactive teaching tools has become a priority for educators. Our objective is to demystify complex quantum mechanical concepts, spark students’ interest in learning, and deepen their understanding, ultimately improving teaching effectiveness. In our research, we used LabVIEW software to develop a visual display and interactive simulation for double-slit interference and circular aperture diffraction experiments of electrons. This module allows students to simulate these experiments and adjust parameters, providing an intuitive observation of quantum behavior under various conditions. The results indicate that using the LabVIEW multimedia module significantly enhances students’ comprehension and interest in quantum mechanics, particularly with respect to wave-particle duality. We also employed the Feynman path integral idea to explain some of the simulation phenomena. This LabVIEW-based simulation not only renders abstract concepts more tangible and visual but also fosters active learning and experimental investigation. We posit that this study introduces a novel and valuable tool for teaching quantum mechanics and provides insights for the future of quantum mechanics education.

A demonstration of particle duality of light

Qiuhua Sun, Jiang Haili, Zhihai Liu +1 more

The need of understanding and teaching about wave-particle duality if light with gets more and more apparent in the background of the attention of modern physics. As early as the beginning of twentieth Century, Einstein dared to "deny" the development of a very perfect light electromagnetic theory, so that the quantum of light can be developed. In 1924, De Broglie put forward wave-particle duality if light to other micro particles and the concept of matter wave, pointed out that all micro particle has wave-particle duality. This is a very abstract concept for students, most college physics teaching all lack of demonstration about particle duality of light. The present article aims to contribute to demonstrate the wave-particle duality of light at the same time using a simple way based on fiber optical tweezers. It is hoped that useful lesson can be absorbed so that students can deepen the understanding of the particle and wave properties of light. To complement the demonstration experiment for this attribute light has momentum.

The wave-particle duality of light: A demonstration experiment

Todorka L. Dimitrova, Antoine Weis

The wave-particle duality of light plays a fundamental role in introductory courses on quantum mechanics. Traditionally the wave and particle aspects of light are demonstrated in separate experiments which makes it difficult for students to understand their complementary nature. We present an experiment using a single apparatus that demonstrates the wave aspect, the particle aspect, and most importantly, their coexistence. The apparatus is based on a Mach-Zehnder interferometer in which a light beam is attenuated so that at each instant there is only a single photon in the interferometer. In this way the observation of single photon interference becomes possible. By integrating the single photon events in a storage oscilloscope the evolution toward classical interference fringes can be shown in real time. A second strong laser beam, derived from the same pointer, but slightly displaced, traverses the interferometer at the same time, allowing the simultaneous demonstration of wave aspects. Special features of the setup are low cost, simplicity, didactical power and suitability for presentations in large lecture halls using both multimedia projections and audible signals.
