Certification of non-Gaussian states with operational measurements
Ulysse Chabaud, Ganaël Roeland, Mattia Walschaers +4
We derive a theoretical framework for the experimental certification of non-Gaussian features of quantum states using double homodyne detection. We rank experimental non-Gaussian s…
Classical simulation of Gaussian quantum circuits with non-Gaussian input states
Ulysse Chabaud, Giulia Ferrini, Frédéric Grosshans +1
We consider Gaussian quantum circuits supplemented with non-Gaussian input states and derive sufficient conditions for efficient classical strong simulation of these circuits. In p…
Optimal quantum-programmable projective measurements with coherent states
Niraj Kumar, Ulysse Chabaud, Elham Kashefi +2
We consider a device which can be programmed using coherent states of light to approximate a given projective measurement on an input coherent state. We provide and discuss three p…
Breaking simple quantum position verification protocols with little entanglement
Andrea Olivo, Ulysse Chabaud, André Chailloux +1
Instantaneous nonlocal quantum computation (INQC) evades apparent quantum and relativistic constraints and allows to attack generic quantum position verification (QPV) protocols (a…
Efficient verification of Boson Sampling
Ulysse Chabaud, Frédéric Grosshans, Elham Kashefi +1
The demonstration of quantum speedup, also known as quantum computational supremacy, that is the ability of quantum computers to outperform dramatically their classical counterpart…
Quantum weak coin flipping with a single photon
Mathieu Bozzio, Ulysse Chabaud, Iordanis Kerenidis +1
Weak coin flipping is among the fundamental cryptographic primitives which ensure the security of modern communication networks. It allows two mistrustful parties to remotely agree…
