Measure-independent anomaly of nonlocality
S. Camalet
We show that any Bell local state, with a hidden nonlocality that can be revealed by local filtering, is more, or equally, entangled than nonlocal states. More precisely, it can be…
Classical multiparty computation using quantum resources
Marco Clementi, Anna Pappa, Andreas Eckstein +3
In this work, we demonstrate a new way to perform classical multiparty computing amongst parties with limited computational resources. Our method harnesses quantum resources to inc…
Statistical signatures of multimode single-photon added and subtracted states of light
Mattia Walschaers, Claude Fabre, Valentina Parigi +1
The addition or subtraction of a photon from a Gaussian state of light is a versatile and experimentally feasible procedure to create non-Gaussian states. In multimode setups, thes…
Continuous-Variable Sampling from Photon-Added or Photon-Subtracted Squeezed States
Ulysse Chabaud, Tom Douce, Damian Markham +3
We introduce a new family of quantum circuits in Continuous Variables and we show that, relying on the widely accepted conjecture that the polynomial hierarchy of complexity classe…
Entanglement and Wigner function negativity of multimode non-Gaussian states
Mattia Walschaers, Claude Fabre, Valentina Parigi +1
Non-Gaussian operations are essential to exploit the quantum advantages in optical continuous variable quantum information protocols. We focus on mode-selective photon addition and…
A two-particle, four-mode interferometer for atoms
Pierre Dussarrat, Maxime Perrier, Almazbek Imanaliev +5
We present a free-space interferometer to observe two-particle interference of a pair of atoms with entangled momenta. The source of atom pairs is a Bose--Einstein condensate subje…
