Temporal modes of quantum states of light scattered by a two-level system
Yann Bouchereau, Lucas Weitzel, Valerian Thiel +4
Non-Gaussian quantum states of light are of paramount importance to quantum computing. Nevertheless, their deterministic generation is challenging problem due to the difficulty to…
Resourcefulness of non-classical continuous-variable quantum gates
Massimo Frigerio, Antoine Debray, Nicolas Treps +1
In continuous-variable quantum computation, identifying key elements that enable a quantum computational advantage is a long-standing issue. Starting from the standard results on t…
Tunable passive squeezing of squeezed light through unbalanced double homodyne detection
Niels Tripier-Mondancin, David Barral, Ganaël Roeland +3
The full characterization of quantum states of light is a central task in quantum optics and information science. Double homodyne detection provides a powerful method for the direc…
Homodyne detection for pulse-by-pulse squeezing measurements
Tiphaine Kouadou, Elie Gozlan, Loïc Garcia +11
Homodyne detection is a phase-sensitive measurement technique, essential for the characterization of continuous-variable (CV)-encoded quantum states of light. It is a key component…
Optimal Moment-based Characterization of a Gaussian State
Niels Tripier-Mondancin, Ilya Karuseichyk, Mattia Walschaers +2
Fast and precise characterization of Gaussian states is crucial for their effective use in quantum technologies. In this work, we apply a multi-parameter moment-based estimation me…
