The sky of quantum light is not flat
In a recent study, researchers from the QITE team at MPQ and from the department of Mathematics of ENS have refined the mathematical framework needed to coherently describe quantum states involving multiple photons. (Left) When the phase reference is explicitly...
An optomechanical disk in its fundamental state of motion
The motion of a mesoscopic mechanical resonator can exhibit quantum behavior when cooled to very low temperatures. In particular, it can reach its ground state and cease to vibrate. Using light as a probe, the LIME team at the MPQ laboratory demonstrated that...
Exact low-energy duality in superconducting quantum circuits
The THEORIE team, in collaboration with Michel H. Devoret, has published a theoretical study in Physical Review Letters demonstrating an exact low-energy duality in circuits where a Josephson junction is coupled to a multi-mode environment. These systems exhibit a...
Multiphysics optomechanical sensing of a liquid on the micron scale
The LIME team at MPQ laboratory, in collaboration with CEA LETI in Grenoble, has published an article in Microsystems & Nanoengineering presenting an optomechanical platform for characterizing the rheological, optical, and thermal properties of fluids at the...
