Quantum Phenomena Controlled at Room Temperature in Groundbreaking Study

Overview

• 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.
