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…
Deterministic randomness extraction for quantum random number generation with partial trust
Pablo Tikas Pueyo, Tomás Fernández Martos, Gabriel Senno
It is a well-known fact in classical information theory that no deterministic procedure can extract close-to-ideal randomness from an arbitrary entropy source. On the other hand, i…
Entanglement in the energy-constrained prepare-and-measure scenario: applications to randomness certification and channel discrimination
Raffaele D'Avino, Gabriel Senno, Mir Alimuddin +1
Quantum information tasks are often analyzed under varying trust assumptions about the devices involved. The semi-device-independent (SDI) framework offers a balance between needed…
Maximal intrinsic randomness of noisy quantum measurements
Fionnuala Curran, Morteza Moradi, Gabriel Senno +2
Quantum physics exhibits an intrinsic and private form of randomness with no classical counterpart. Any setup for quantum randomness generation involves measurements acting on quan…
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…
