The demonstration of a single-particle interferometer opens the door to a number of applications, from investigations of gravity to surface impact physics.

Colliding matter waves from a Bose-Einstein condensate violate a relation called the Cauchy-Schwarz inequality, proving that such interactions must be considered quantum mechanically.

An optomechanical system in which light and matter exchange roles promises new kinds of quantum states.

Shifts in atomic energy levels caused by electron interaction with virtual photons can also occur in an ensemble of atoms acting cooperatively.

The sloshing of light between optical waveguides replicates the quantum-mechanical exchange between an atom and an electromagnetic mode.

The next generation of ultrahigh energy lasers will be able to produce extremely dense electron-positron plasmas and intense bursts of gamma rays, according to simulations, and both will lead to new types of experiments.

A waveguide’s dielectric properties could result in an effective gauge field for photons even though they have no charge.

Quantum interference of pairs of photons emitted by nitrogen-vacancy centers in diamond paves the way for entanglement of distant qubits.

Although the quantum Rabi model is the simplest model describing the coupling of quantum light and matter, only now has an analytical solution been found.

Researchers caught a single particle of light in two places at once.

Physicists have developed a system that emits single photons on a precise schedule.

Researchers have caused ‘matter waves’ to immitate x-rays by diffracting them through ‘crystals of light’.
