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…
When Quantum Nonlocality Does Not Play Dice
Ravishankar Ramanathan, Yuan Liu, Stefano Pironio
Bell nonlocality is widely viewed as a signature of intrinsic randomness, effectively playing the role of a 'dice' at the heart of many device-independent cryptographic protocols.…
Information capacity of quantum communication under natural physical assumptions
Jef Pauwels, Stefano Pironio, Armin Tavakoli
The quantum prepare-and-measure scenario has been studied under various physical assumptions on the emitted states. Here, we first discuss how different assumptions are conceptuall…
Device-Independent Quantum Key Distribution Based on Routed Bell Tests
Tristan Le Roy-Deloison, Edwin Peter Lobo, Jef Pauwels +1
Photon losses are the main obstacle to fully photonic implementations of device-independent quantum key distribution (DIQKD). Motivated by recent work showing that routed Bell scen…
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…
