Squeezed states of light are characterized by a reduced uncertainty in one of their conjugate quadratures which can be below that of vacuum. These states have become an important resource in quantum technologies. This talk explores their dual application in creating cluster states for continuous-variable quantum computing (CVQC) and enhancing sensitivity in quantum sensing. We focus on the application of these quantum technologies on Photonic integrated Chips (PIC) and more precicely we’ll discussed the compact generation of cluster states using multi frequency pumps and the quantum-enhanced Raman spectroscopy measurements, showcasing how squeezed light improves signal detection and precision beyond classical limits. By bridging foundational theory and practical applications, we emphasize the great potential of squeezed states in the advancement of quantum information processing and precision measurements.
