A single programmable photonic circuit for universal quantum measurements
Wen-Zhe Yan, Lan-Tian Feng, Zhibo Hou +7
Programmable photonic quantum processors face a critical challenge: despite significant advances in quantum state preparation and manipulation, measurements remain limited to proje…
The role of entanglement in energy-restricted communication and randomness generation
Carles Roch I Carceller, Armin Tavakoli
A promising platform for semi-device-independent quantum information is prepare-and-measure experiments restricted only by a bound on the energy of the communication. Here, we inve…
Entanglement Structure Certification Based on Energy-Restricted State Discrimination
Carles Roch I Carceller
The certification of entanglement in multipartite scenarios is crucial for the advancement of quantum technologies, particularly for the realization of large-scale quantum networks…
Unlimited quantum correlation advantage from bound entanglement
Armin Tavakoli, Carles Roch i Carceller, Lucas Tendick +1
Entangled states that cannot be distilled to maximal entanglement are called bound entangled and they are often viewed as too weak to break the limitations of classical models. Her…
Prepare-and-measure scenarios with photon-number constraints
Carles Roch i Carceller, Jef Pauwels, Stefano Pironio +1
We study correlations in the prepare-and-measure scenario when quantum communication is constrained by photon-number statistics. Such constraints are natural and practical control…
Global restrictions under local state discrimination
Carles Roch I Carceller, Alexander Bernal
We investigate how local distinguishability can restrict global properties of bi-partite states. We begin exploring how non-locality becomes limited by optimal local state discrimi…
