Full title: SMARTly Quantum Light Source for Einstein Telescope
Funding: PRIN PNRR 2022
Scientific Coordinator: Maria Parisi (CNR-INO, Naples)
Project Objective:
The SMART_Q_ET project aims to develop a compact, robust, and high-performance source of squeezed quantum light designed for integration into the third-generation gravitational wave detector Einstein Telescope (ET). The main goal is to enhance the sensitivity of optical detection systems beyond the standard quantum limit, especially in the mid-to-low frequency bands.
Main Activities:
- Design and prototyping of squeezed light sources based on cascaded nonlinear optical processes.
- Theoretical modeling and simulations of optimized configurations for advanced interferometers.
- Development of balanced homodyne detection techniques for the characterization and validation of the quantum sources.
Key Technologies:
- Frequency-dependent squeezed light generation.
- Compact and thermally stable optical architectures.
- Advanced nonlinear optics, including crystals and microresonator-based platforms.

Expected Impact:
The project aims to demonstrate a compact and reliable squeezed light source that meets the demanding requirements of next-generation gravitational wave observatories, such as the Einstein Telescope. By pushing the boundaries of quantum optics, it contributes to the broader advancement of quantum technologies for high-precision metrology, enabling measurements with sensitivities beyond classical limits. The outcomes of this research hold promise for a range of applications, including advanced spectroscopy, secure quantum communication, and the detection of extremely weak signals in both fundamental science and emerging technologies.
