Researchers from the University of Innsbruck and ETH Zurich showed that
According to the authors of the study, previouslyit is proved that mechanical quantum compression reduces the uncertainty of fluctuations below zero oscillations. In their work, scientists propose a new approach designed for levitating mechanical systems.
"We're showing what's rightthe designed optical resonator can be used to quickly and strongly limit the movement of a levitating nanoparticle,” says Katja Kustura, a research participant from the University of Innsbruck.
In an optical resonator, light is reflected betweenmirrors and interacts with the levitating nanoparticle. Such an interaction can lead to dynamic instability, which is usually considered undesirable. The authors of the study believe that this side effect can be used to create sensors.
“In our work we show that with the rightBy controlling these instabilities, the resulting unstable dynamics of the mechanical oscillator inside the optical resonator leads to mechanical compression,” says Kustura.
In their work, the researchers demonstratedthese effects using silica nanoparticles. Scientists believe that quantum sensors created using this technology can be used, for example, in satellite missions, self-driving cars and seismology.
