Locality of temperature in spin chains
Senaida Hernández-Santana, Arnau Riera, Karen Hovhannisyan +3
In traditional thermodynamics, temperature is a local quantity: a subsystem of a large thermal system is in a thermal state at the same temperature as the original system. For stro…
Nonlocality in many-body quantum systems detected with two-body correlators
J. Tura, R. Augusiak, A. B. Sainz +4
Contemporary understanding of correlations in quantum many-body systems and in quantum phase transitions is based to a large extent on the recent intensive studies of entanglement…
Optimal randomness certification from one entangled bit
Antonio Acín, Stefano Pironio, Tamás Vértesi +1
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 measur…
Necessary detection efficiencies for secure quantum key distribution and bound randomness
Antonio Acín, Daniel Cavalcanti, Elsa Passaro +2
In recent years, several hacking attacks have broken the security of quantum cryptography implementations by exploiting the presence of losses and the ability of the eavesdropper t…
Optimal randomness certification in the quantum steering and prepare-and-measure scenarios
Elsa Passaro, Daniel Cavalcanti, Paul Skrzypczyk +1
Quantum mechanics predicts the existence of intrinsically random processes. Contrary to classical randomness, this lack of predictability can not be attributed to ignorance or lack…
Entanglement and Nonlocality in Many-Body Systems: a primer
J. Tura, A. B. Sainz, T. Grass +3
Current understanding of correlations and quantum phase transitions in many-body systems has significantly improved thanks to the recent intensive studies of their entanglement pro…
