Joint-measurability and quantum communication with untrusted devices
Michele Masini, Marie Ioannou, Nicolas Brunner +2
Photon loss represents a major challenge for the implementation of quantum communication protocols with untrusted devices, e.g. in the device-independent (DI) or semi-DI approaches…
Towards the device-independent certification of a quantum memory
Pavel Sekatski, Jean-Daniel Bancal, Marie Ioannou +2
Quantum memories represent one of the main ingredients of future quantum communication networks. Their certification is therefore a key challenge. Here we develop efficient certifi…
Equivalence between simulability of high-dimensional measurements and high-dimensional steering
Benjamin D. M. Jones, Roope Uola, Thomas Cope +4
The effect of quantum steering arises from the judicious combination of an entangled state with a set of incompatible measurements. Recently, it was shown that this form of quantum…
Simulability of high-dimensional quantum measurements
Marie Ioannou, Pavel Sekatski, Sébastien Designolle +3
We investigate the compression of quantum information with respect to a given set of high-dimensional measurements. This leads to a notion of simulability, where we d…
Noncommutative polynomial optimization under symmetry
Marie Ioannou, Denis Rosset
We present a general framework to exploit the symmetries present in the Navascu{é}s-Pironio-Ac{í}n semidefinite relaxations that approximate invariant noncommutative polynomial opt…
Steering-based randomness certification with squeezed states and homodyne measurements
Marie Ioannou, Bradley Longstaff, Mikkel V. Larsen +5
We present a scheme for quantum randomness certification based on quantum steering. The protocol is one-sided device independent, providing high security, but requires only states…
