Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales.
And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.Researchers at the University of East Anglia have proposed a new way of using quantum light to 'see' quantum sound.
And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems. "These processes are typically investigated using techniques that rely on polarisation -- the same property of light used in sunglasses to reduce reflections. But this is a classical phenomenon."Techniques from quantum optics, the field of physics that studies the quantum nature of light and its interactions with matter on the atomic scale, can offer a way to investigate genuine quantum effects directly in molecular systems.
While photons are routinely created and measured in laboratories all over the world, individual quanta of vibrations, which are the corresponding particles of sound, phonons, cannot in general be similarly measured.Lead researcher Dr Garth Jones, from UEA's School of Chemistry, said:"We have also computed correlations between photon and phonons.
