Certified randomness amplification by dynamically probing remote random quantum states
Minzhao Liu, Pradeep Niroula, Matthew DeCross +49
Cryptography depends on truly unpredictable numbers, but physical sources emit biased or correlated bits. Quantum mechanics enables the amplification of imperfect randomness into n…
An efficient construction of Raz's two-source randomness extractor with improved parameters
Cameron Foreman, Lewis Wooltorton, Kevin Milner +1
Randomness extractors are algorithms that distill weak random sources into near-perfect random numbers. Two-source extractors enable this distillation process by combining two inde…
More entropy from shorter experiments using polytope approximations to the quantum set
Hyejung H. Jee, Florian J. Curchod, Mafalda L. Almeida
We introduce a systematic method for constructing polytope approximations to the quantum set in a variety of device-independent quantum random number generation (DI-QRNG) protocols…
Certified randomness using a trapped-ion quantum processor
Minzhao Liu, Ruslan Shaydulin, Pradeep Niroula +29
While quantum computers have the potential to perform a wide range of practically important tasks beyond the capabilities of classical computers, realizing this potential remains a…
Statistical testing of random number generators and their improvement using randomness extraction
Cameron Foreman, Richie Yeung, Florian J. Curchod
Random number generators (RNGs) are notoriously challenging to build and test, especially for cryptographic applications. While statistical tests cannot definitively guarantee an R…
Cryptomite: A versatile and user-friendly library of randomness extractors
Cameron Foreman, Richie Yeung, Alec Edgington +1
We present Cryptomite, a Python library of randomness extractor implementations. The library offers a range of two-source, seeded and deterministic randomness extractors, together…
Practical randomness amplification and privatisation with implementations on quantum computers
Cameron Foreman, Sherilyn Wright, Alec Edgington +2
We present an end-to-end and practical randomness amplification and privatisation protocol based on Bell tests. This allows the building of device-independent random number generat…
A versatile construction of Bell inequalities for the multipartite scenario
Florian J. Curchod, Mafalda L. Almeida, Antonio Acín
Local measurements acting on entangled quantum states give rise to a rich correlation structure in the multipartite scenario. We introduce a versatile technique to build families o…
Entangled systems are unbounded sources of nonlocal correlations and of certified random numbers
Florian J. Curchod, Markus Johansson, Remigiusz Augusiak +3
The outcomes of local measurements made on entangled systems can be certified to be random provided that the generated statistics violate a Bell inequality. This way of producing r…
Towards an equivalence between maximal entanglement and maximal quantum nonlocality
Victoria Lipinska, Florian Curchod, Alejandro Máttar +1
While all bipartite pure entangled states are known to generate correlations violating a Bell inequality, and are therefore nonlocal, the quantitative relation between pure-state e…
Unbounded randomness certification using sequences of measurements
F. J. Curchod, M. Johansson, R. Augusiak +3
Unpredictability, or randomness, of the outcomes of measurements made on an entangled state can be certified provided that the statistics violate a Bell inequality. In the standard…
Quantifying multipartite nonlocality via the size of the resource
Florian John Curchod, Nicolas Gisin, Yeong-Cherng Liang
The generation of (Bell-)nonlocal correlations, i.e., correlations leading to the violation of a Bell-like inequality, requires the usage of a nonlocal resource, such as an entangl…
Anonymous Quantum Nonlocality
Yeong-Cherng Liang, Florian John Curchod, Joseph Bowles +1
We show that for all , an example of an -partite quantum correlation that is not genuinely multipartite nonlocal but rather exhibiting anonymous nonlocality, that is, non…
Multipartite Nonlocality as a Resource and Quantum Correlations Having Indefinite Causal Order
Florian Curchod, Yeong-Cherng Liang, Nicolas Gisin
The characterization of quantum correlations in terms of information-theoretic resource has been a fruitful approach to understand the power of quantum correlations as a resource.…
