A semi-definite programming formulation of the device-dependent guessing probability
Raffaele D'Avino, Aurora Mugnai, Miguel Navascués +2
In quantum mechanics, a measurement applied to a state in general produces some amount of intrinsic randomness. This is not only a fundamental feature of the theory, but is also at…
Certifying ground-state properties of quantum many-body systems
Jie Wang, Jacopo Surace, Irénée Frérot +4
A ubiquitous problem in quantum physics is to understand the ground-state properties of many-body systems. Confronted with the fact that exact diagonalisation quickly becomes impos…
Security of discrete-modulated continuous-variable quantum key distribution
Stefan Bäuml, Carlos Pascual-GarcÃa, Victoria Wright +2
Continuous variable quantum key distribution with discrete modulation has the potential to provide information-theoretic security using widely available optical elements and existi…
Maximal intrinsic randomness of a quantum state
Shuyang Meng, Fionnuala Curran, Gabriel Senno +4
One of the most counterintuitive aspects of quantum theory is its claim that there is 'intrinsic' randomness in the physical world. Quantum information science has greatly progress…
