Versatile photonic entanglement synthesizer in the spatial domain
David Barral, Mattia Walschaers, Kamel Bencheikh +4
Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top b…
Remote generation of Wigner-negativity through Einstein-Podolsky-Rosen steering
Mattia Walschaers, Nicolas Treps
Negativity of the Wigner function is seen as a crucial resource for reaching a quantum computational advantage with continuous variable systems. However, these systems, while they…
Signatures of Many-Particle Interference
Mattia Walschaers
This Tutorial will introduce the mathematical framework for describing systems of identical particles, and explain the notion of indistinguishability. We will then focus our attent…
Mode-Dependent Loss Model for Multimode Photon-Subtracted States
Mattia Walschaers, Young-Sik Ra, Nicolas Treps
Multimode photon-subtraction provides an experimentally feasible option to construct large non-Gaussian quantum states in continuous-variable quantum optics. The non-Gaussian featu…
Validating multi-photon quantum interference with finite data
Fulvio Flamini, Mattia Walschaers, Nicolò Spagnolo +3
Multi-particle interference is a key resource for quantum information processing, as exemplified by Boson Sampling. Hence, given its fragile nature, an essential desideratum is a s…
Non-Gaussian quantum states of a multimode light field
Young-Sik Ra, Adrien Dufour, Mattia Walschaers +4
Even though Gaussian quantum states of multimode light are promising quantum resources due to their scalability, non-Gaussianity is indispensable for quantum technologies, in parti…
