Published purpose

Quantum states of light with a macroscopic number of photons, generally referred to as squeezed light, are entangled fields underpinning quantum metrology (imaging, spectroscopy and interferometry), secure communication (key exchange and authentication), and quantum computing. Short, squeezed pulses are an asset for the emerging field of quantum spectroscopy and microscopy and are required to perform measurement of ultrafast transient effects with sensitivities exceeding those available with classical means. However, generating broadband squeezed states of light with coherence times less than 100 fs, in a single temporal mode, is challenging. This project aims at generating such states with the novel concept of Fourier plane Optical Parametric Amplification, a technology patented by the firm (Few-Cycle).
