Researchers at the University of East Anglia have proposed a new way of using quantum light to ‘see’ quantum sound.

A new paper published today 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.

Dr Magnus Borgh from UEA’s School of Physics said: “There is a long-standing controversy in chemical physics about the nature of processes where energy from particles of light is transferred ...

3 sources of single photons: represented by a red dot at the center of the cavity, the semiconductor quantum dots (of nanometric size) is inserted in the center of the cavity, which consists of a 3 µm pillar connected to a circular frame by guides that are 1.3 µm wide. By applying electrical voltage to the cavity, the wavelength of the emitted photons can be tuned and the charge noise totally eliminated.

A new ultra-bright source of single photons – 15X brighter than commonly used sources and emitting photons that are 99.5% indistinguishable from one another – has been developed by researchers from the CNRS, Université Paris Diderot, and Université Paris-Sud...
