Laser loop couples quantum systems over a distance

For the first time, researchers have succeeded in creating strong coupling between quantum systems over a great distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly ...

State-of-the-art lasers at the micro level

Many emerging technologies rely on high-quality lasers. Laser-based LiDAR sensors can provide highly accurate scans of three-dimensional spaces, and as such are crucial in applications ranging from autonomous vehicles to ...

Quantum gases won't take the heat

The quantum world blatantly defies intuitions that we've developed while living among relatively large things, like cars, pennies and dust motes. In the quantum world, tiny particles can maintain a special connection over ...

Quantum-entangled light from a vibrating membrane

Entanglement, a powerful form of correlation among quantum systems, is an important resource for quantum computing. Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently ...

Using noise to enhance optical sensing

In conventional sensing methods, noise is always a problem, especially in systems that are meant to detect changes in their environment that are hardly bigger or even smaller than the noise in the system. Encountering this ...

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 ...

Computing with spins of light

A laser system that generates spinning light particles could lead to the strong kind of computational power needed to solve complex biological problems. The system, which improves on previous ones, is described in the journal ...
