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…
Bound entangled states are useful in prepare-and-measure scenarios
Carles Roch I Carceller, Armin Tavakoli
We show that bipartite bound entangled states make possible violations of correlation inequalities in the prepare-and-measure scenario. These inequalities are satisfied by all clas…
Semidefinite relaxations for high-dimensional entanglement in the steering scenario
Nicola D'Alessandro, Carles Roch i Carceller, Armin Tavakoli
We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method…
Improving semi-device-independent randomness certification by entropy accumulation
Carles Roch I Carceller, Lucas Nunes Faria, Zheng-Hao Liu +4
Certified randomness guaranteed to be unpredictable by adversaries is central to information security. The fundamental randomness inherent in quantum physics makes certification po…
Scalable entanglement certification via quantum communication
Pharnam Bakhshinezhad, Mohammad Mehboudi, Carles Roch i Carceller +1
Harnessing the advantages of shared entanglement for sending quantum messages often requires the implementation of complex two-particle entangled measurements. We investigate entan…
