In a paper recently published in Nature Communications, researchers from the Paul-Drude-Institut in Berlin, and the Instituto Balseiro in Argentina, demonstrated that the mixing of confined quantum fluids of light and GHz sound leads to the emergence of an elusive quasi-particle: the phonoriton. This discovery opens a novel way to coherently convert information between optical and microwave domains, bringing potential benefits to photonics, optomechanics, and optical communication technologies.

In a paper published today in Nature Communications, researchers from the Paul Drude Institute in Berlin, Germany, and the Instituto Balseiro, Bariloche, Argentina, demonstrated that light emitters with different resonance frequencies can asynchronously self-lock their relative energies by exchanging mechanical energy. This finding paves the way for increased control of light sources and GHz-to-THz interconversion relevant to quantum technology.

Scalable quantum networks require on-chip transfer and manipulation of single particles as well as their interconversion to single photons for long-range information exchange.

Researchers from the Paul-Drude-Institut in Berlin, the Helmholtz-Zentrum in Dresden and the Ioffe Institute in St. Petersburg have demonstrated the use of elastic vibrations to manipulate the spin states of optically active color centers in SiC at room temperature.
