Rigorous no-go theorems for heralded linear-optical state generation tasks
Deepesh Singh, Ryan J. Marshman, Luis Villegas-Aguilar +2
A major challenge in photonic quantum technologies is developing strategies to prepare suitable discrete-variable quantum states using simple input states, linear optics, and auxil…
A heralded quantum amplifier of multi-photon states
Luis Villegas-Aguilar, Farzad Ghafari, Matthew S. Winnel +5
Large-scale quantum networking systems will inevitably require methods to overcome photon loss. While the no-cloning theorem forbids perfect and deterministic amplification of unkn…
Experimental quantum randomness enhanced by a quantum network
Emanuele Polino, Luis Villegas-Aguilar, Davide Poderini +10
The certification of randomness is essential for both fundamental science and information technologies. Unlike traditional random number generators, randomness obtained from nonloc…
Quantum Assemblage Tomography
Luis Villegas-Aguilar, Yuanlong Wang, Alex Pepper +7
A central requirement in asymmetric quantum nonlocality protocols, such as quantum steering, is the precise reconstruction of state assemblages -- statistical ensembles of quantum…
A robust approach for time-bin encoded photonic quantum information protocols
Simon J. U. White, Emanuele Polino, Farzad Ghafari +6
Quantum states encoded in the time-bin degree of freedom of photons represent a fundamental resource for quantum information protocols. Traditional methods for generating and measu…
Nonlocality activation in a photonic quantum network
Luis Villegas-Aguilar, Emanuele Polino, Farzad Ghafari +9
Bell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocal…
