Partially-Commutative Polynomial Optimization
Abhishek Mishra, Moisés Bermejo Morán, Stefano Pironio
Semidefinite programming hierarchies for commutative and non-commutative polynomial optimization represent a powerful computational tool with many applications in quantum informati…
When Quantum Nonlocality Does Not Play Dice
Ravishankar Ramanathan, Yuan Liu, Stefano Pironio
The authors demonstrate that certain Bell inequalities can be maximally violated by quantum correlations yet certify no randomness for any fixed input pair, and they construct expl…
Generalized measurement incompatibility
Edwin Peter Lobo, Maria Balanzó-Juandó, Stefano Pironio
Quantum measurements can be incompatible, i.e., they can fail to be jointly measurable. Recently, a weaker notion of joint-measurability, called partial joint-measurability, was pr…
No Bound Randomness in Quantum Nonlocality
Ravishankar Ramanathan, Yuan Liu, Yutian Wu +1
Recently it has been found that there exist maximally nonlocal quantum correlations that fail to certify randomness for any fixed input pair, rendering them useless for device-inde…
Certification of quantum correlations and DIQKD at arbitrary distances through routed Bell tests
Pavel Sekatski, Jef Pauwels, Edwin Peter Lobo +2
Transmission loss represents a major obstacle to the device-independent certification of quantum correlations over long distances, limiting applications such as device-independent…
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…
