In quantum information sciences and technologies, light is an excellent candidate as information carrier due to the possibility of realizing optical qubits that can be transmitted though optical fibres, manipulated by means of linear optics and interfaced with matter.The wave-particle duality of light has led to two traditionally-separated...

Optical non-Gaussian quantum states can be generated in a heralded manner by applying a photon subtraction operation to a Gaussian input state. In our work, we develop a theoretical framework to describe this operation in the case where the input state is spectrally multimode. This framework allows the optimal design of photon subtraction...

This paper establishes a versatile theoretical framework that explicitly describes single-photon subtractionfrom multimode quantum light in the context of non-Gaussian state generation and manipulation. The treatmentfocuses on easy-to-implement configurations in which no mode-selective operation is available and evaluatesfeatures and advantages...

In the context of emerging quantum technologies, this work marks an important progress towards practical quantum optical systems in the continuous variable regime. It shows the feasibility of experiments where non-Gaussian state generation entirely relies on plug-and-play components from guided-wave optics technologies. This strategy is...

This work marks an important progress towards practical quantum optical technologies in the continuous variable regime, as it shows the feasibility of experiments where non-Gaussian state generation entirely relies on plug-&-play components from guided-wave optics technologies. This strategy is demonstrated experimentally with the heralded...
