Scattering-lens based quantum imaging beyond shot noise

Area of Science:

• Quantum optics
• Optical imaging

Background:

• Classical optical imaging with scattering lenses offers super-diffraction-limit resolution.
• Coherent states used in such systems are limited by shot noise, impacting signal-to-noise ratio and resolution.

Purpose of the Study:

• To theoretically propose a novel optical imaging scheme using squeezed states.
• To overcome the shot-noise limitations inherent in coherent-state-based imaging.

Main Methods:

• Theoretical proposal of an optical imaging scheme utilizing squeezed states as input.
• Analysis of quantum noise suppression below the shot-noise level.

Main Results:

• The proposed scheme achieves an enhanced signal-to-noise ratio compared to coherent-state imaging with scattering lenses.
• Demonstrated improvement in resolution beyond classical limits.

Conclusions:

• Squeezed states offer a viable method for enhancing optical imaging performance.
• This quantum approach provides superior signal-to-noise ratio and resolution compared to traditional coherent-state methods.
