Stirring a superfluid with a laser

Scientists from the Graduate School of Engineering Science at Osaka University used optical tweezers for the first time inside superfluid helium. With a strongly focused beam of light, they demonstrated the stable trapping ...

Minimizing laser phase noise with machine learning

Ultra-precise lasers can be used for optical atomic clocks, quantum computers, power cable monitoring, and much more. But all lasers make noise, which researchers from DTU Fotonik want to minimize using machine learning.

Integrated photonics meets electron microscopy

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics—circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes ...

In the quantum realm, not even time flows as you might expect

A team of physicists at the Universities of Bristol, Vienna, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum systems can simultaneously evolve along two ...

Implementing a 46-node quantum metropolitan area network

Quantum key distribution (QKD) is a method used for secure or secret key exchanges between two remote users. Using secure communication, cyberscientists ultimately aim to establish a global quantum network. Existing field ...

Quantum emitters: Beyond crystal clear to single-photon pure

Photons, fundamental particles of light, are carrying these words to your eyes via the light from your computer screen or phone. Photons play a key role in the next-generation quantum information technology, such as quantum ...
