A quantum of solid: A glass nanoparticle in the quantum regime

Researchers in Austria have used lasers to levitate and cool a glass nanoparticle into the quantum regime. Although it is trapped in a room-temperature environment, the particle's motion is solely governed by the laws of ...

Light-based 'tractor beam' assembles materials at the nanoscale

Modern construction is a precision endeavor. Builders must use components manufactured to meet specific standards—such as beams of a desired composition or rivets of a specific size. The building industry relies on manufacturers ...

Entanglement sent over 50 km of optical fiber

The quantum internet promises absolutely tap-proof communication and powerful distributed sensor networks for new science and technology. However, because quantum information cannot be copied, it is not possible to send this ...

Microscopic glass blowing used to make tiny optical lenses

Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature ...

Reactive optical matter: Light-induced motion

Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
