Bell inequalities for three systems and arbitrarily many measurement outcomes
, 2012 We present a family of Bell inequalities for three parties and arbitrarily many outcomes, which can be seen as a natural generalization of the Mermin Bell inequality.

Using complete measurement statistics for optimal device-independent randomness evaluation
New Journal of Physics, 2014 The majority of recent works investigating the link between non-locality and randomness, e.g. in the context of device-independent cryptography, do so with respect to some specific Bell inequality, usually the CHSH inequality.

Security of Device-Independent Quantum Key Distribution in the Bounded-Quantum-Storage Model
Physical Review X, 2013 Device-independent quantum key distribution (DIQKD) is a formalism that supersedes traditional quantum key distribution, as its security does not rely on any detailed modeling of the internal working of the devices.

All Pure Bipartite Entangled States can be Self-Tested [PDF]
, 2017 Device-independent self-testing allows to uniquely characterize the quantum state shared by untrusted parties (up to local isometries) by simply inspecting their correlations, and requiring only minimal assumptions, namely a no-signaling constraint on ...

Device-independent randomness generation from several Bell estimators
New Journal of Physics, 2018 Device-independent randomness generation and quantum key distribution protocols rely on a fundamental relation between the non-locality of quantum theory and its random character.

Joint-measurability and quantum communication with untrusted devices [PDF]
QuantumPhoton 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.

Device-independent lower bounds on the conditional von Neumann entropy [PDF]
QuantumThe rates of several device-independent (DI) protocols, including quantum key-distribution (QKD) and randomness expansion (RE), can be computed via an optimization of the conditional von Neumann entropy over a particular class of quantum states.

Classical simulation of entanglement swapping with bounded communication [PDF]
, 2012 Entanglement appears under two different forms in quantum theory, namely as a property of states of joint systems and as a property of measurement eigenstates in joint measurements.

Optimal randomness certification from one entangled bit
, 2015 By performing local projective measurements on a two-qubit entangled state one can certify in a device-independent way up to one bit of randomness. We show here that general measurements, defined by positive-operator-valued measures, can certify up to ...
