Optical estimation of unitary Gaussian processes without phase reference using Fock states

2020 · New Journal of Physics

Abstract Since a general Gaussian process is phase-sensitive, a stable phase reference is required to take advantage of this feature. When the reference is missing, either due to the volatile nature of the measured sample …

Generation of quantum states with nonlinear squeezing by Kerr nonlinearity

2021 · Optics Express

In quantum optics, squeezing corresponds to the process in which fluctuations of a quadrature operator are reduced below the shot noise limit. In turn, nonlinear squeezing can be defined as reduction of fluctuations related to …

Hybrid Code Networks using a convolutional neural network as an input\n layer achieves higher turn accuracy

2019 · arXiv (Cornell University)

The dialogue management is a task of conversational artificial intelligence.\nThe goal of the dialogue manager is to select the appropriate response to the\nconversational partner conditioned by the input message and recent dialogue\nstate. Hybrid Code Networks …

Next Generation Optical Quantum State Synthesis: Observation of Fourfold Negativity in the Wigner Function

2024

An optical quantum state with fourfold Wigner negativity was generated without any loss correction. Generalized photon subtraction scheme, broadband squeezed light source, and high-temporal-resolution transition-edge sensor enabled generation rates of tens of counts per second.
