Quantum Phenomena Controlled at Room Temperature in Groundbreaking Study

Researchers have successfully manipulated quantum effects without the need for extreme cold, paving the way for new quantum technologies.

A team of researchers at EPFL, led by Tobias J. Kippenberg and Nils Johan Engelsen, have achieved control of quantum phenomena at room temperature.
The breakthrough was made possible by creating an ultra-low noise optomechanical system that allows precise manipulation of light and mechanical motion.
The system employs cavity mirrors patterned with phononic crystal structures to minimize thermal noise, enabling the detection of subtle quantum effects.
Optical squeezing, a quantum phenomenon, was demonstrated at room temperature, showcasing the ability to manipulate quantum effects in a macroscopic system.
This advancement could lead to the development of new hybrid quantum systems and enhance the understanding of large, complex quantum states.
