Levitating nanoparticles: physicists from Brno are getting closer to quantum technologies

The prestigious journals Optica a Nature Communications have published the scientific results of the research team of Levitation Photonics, Institute of Photonics of the CAS.


One direction of quantum technology exploits the unique properties of quantum objects interacting with each other, but maximally isolated from the surrounding environment. The topic is presented by Oto Brzobohatý, head of the Levitation Photonics research group.
The research team from the Institute has developed original methods to create such conditions with two nanoparticles levitating in optical traps.

Synchronization of spin-driven limit cycle oscillators optically levitated in vakuum

On September 19, 2023, a press release  was issued on the occasion of the publication of both articles, in which the research was presented by Oto Brzobohatý together with Pavel Zemanek, Head of the Microphotonics Department.

Optical trapping allows non-contact trapping and manipulation of particles in different environments by laser light. In the picture, one particle is trapped in a vacuum in a green laser beam.
