Quantum randomness beyond projective measurements
Fionnuala Curran
The unpredictability of quantum physics gives rise to intrinsic randomness. In an adversarial scenario, any additional degrees of freedom must be attributed to an eavesdropper with…
Unambiguous randomness from a quantum state
Fionnuala Curran
Intrinsic randomness is generated when a quantum state is measured in any basis in which it is not diagonal. In an adversarial scenario, we quantify this randomness by the probabil…
The genuinely multipartite nonlocality of graph states is model-dependent
Xavier Coiteux-Roy, Owidiusz Makuta, Fionnuala Curran +2
Bell's theorem proves that some quantum state correlations can only be explained by bipartite non-classical resources. The notion of genuinely multipartite nonlocality (GMNL) was l…
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…
