Generation of single-mode and two-mode quantum squeezed states of light by degenerate four-wave mixing in a plasmonic waveguide

Researchers have successfully generated quantum squeezed states of light using a novel plasmonic waveguide. This method utilizes degenerate four-wave mixing, a process where light interacts within the waveguide to create these specific quantum states. The experiment demonstrated the ability to produce both single-mode and two-mode squeezed light, offering greater control over the quantum properties of the light generated.

This advancement is significant for the development of quantum technologies, such as quantum computing and enhanced sensing, which rely on precisely controlled quantum states of light.
