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…

Lecture demonstrations of interference and quantum erasing with single photons

Single-photon interference is a beautiful manifestation of the wave–particle duality of light and the double-slit Gedankenexperiment is a standard lecture example for introducing quantum mechanical

A portable double-slit quantum eraser with individual photons

The double-slit experiment has played an important role in physics, from supporting the wave theory of light, via the discussions of the wave–particle duality of light (and matter) to the foundations

Single photon quantum erasing: a demonstration experiment

In the conventional interpretation of quantum mechanics the interference of particles in a two-beam interferometer is closely related to the problem of which-way information. One of the mysteries of

Are there photons in fact?

There are two opposing points of view on the nature of light: the first one manifests the wave-particle duality as a fundamental property of the nature; the second one claims that photons do not

In this paper, I argue that light is a continuous classical electromagnetic wave, while the observed so-called quantum nature of the interaction of light with matter is connected to the discrete

Retention of a Double Slit Single Photon Interference Demonstration of Particle-Wave Duality

In the past there has been great faith in the power of laboratory activities and teacher demonstrations to enhance the learning of physics concepts. However, reviews of the effectiveness turned out

Critique of Wave-Particle Duality of Single-Photons

A prominent way through which wave-particle duality has been ascribed to photons is by illustrating their “wave-like” behaviour in the Mach-Zehnder interferometer and “particle-like” behaviour in the

Software-aided discussion about classical picture of Mach–Zehnder interferometer

The Mach–Zehnder interferometer has played an important role both in quantum and classical physics research over the years. In physics education, it has been used as a didactic tool for quantum

Quantum interference experiments with large molecules

Wave–particle duality is frequently the first topic students encounter in elementary quantum physics. Although this phenomenon has been demonstrated with photons, electrons, neutrons, and atoms, the

Wave‐optical experiments with very cold neutrons

A series of experiments is reviewed on precision measurements of the diffraction of slow neutrons paralleling those with light: diffraction at an absorbing edge, at an absorbing wire, and at single‐

We describe a double-slit interference experiment suitable for a beginning physics laboratory in which single photons are observed to interfere with themselves, directly demonstrating the

Demonstration of single‐electron buildup of an interference pattern

The wave–particle duality of electrons was demonstrated in a kind of two‐slit interference experiment using an electron microscope equipped with an electron biprism and a position‐sensitive
