Device-independent bit commitment based on the CHSH inequality
New Journal of Physics, 2016 Bit commitment and coin flipping occupy a unique place in the device-independent landscape, as the only device-independent protocols thus far suggested for these tasks are reliant on tripartite GHZ correlations.

Randomness in post-selected events
New Journal of Physics, 2016 Bell inequality violations can be used to certify private randomness for use in cryptographic applications. In photonic Bell experiments, a large amount of the data that is generated comes from no-detection events and presumably contains little ...

Quantum violations in the Instrumental scenario and their relations to the Bell scenario [PDF]
Quantum, 2019 The causal structure of any experiment implies restrictions on the observable correlations between measurement outcomes, which are different for experiments exploiting classical, quantum, or post-quantum resources. In the study of Bell nonlocality, these

Simple and practical DIQKD security analysis via BB84-type uncertainty relations and Pauli correlation constraints [PDF]
Quantum, 2022 According to the entropy accumulation theorem, proving the unconditional security of a device-independent quantum key distribution protocol reduces to deriving tradeoff functions, i.e., bounds on the single-round von Neumann entropy of the raw key as a ...

Device-independent quantum key distribution with asymmetric CHSH inequalities [PDF]
Quantum, 2021 The simplest device-independent quantum key distribution protocol is based on the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality and allows two users, Alice and Bob, to generate a secret key if they observe sufficiently strong correlations.

An asymptotic threshold of sufficient randomness for causal inference
Stat, Volume 12, Issue 1, January/December 2023., 2023 For sensitivity analysis with stochastic counterfactuals, we introduce a methodology to characterize uncertainty in causal inference from natural experiments. Our sensitivity parameters are standardized measures of variation in propensity and prognosis probabilities, and one minus their geometric mean is an intuitive measure of randomness in the data ...

Informationally restricted correlations: a general framework for classical and quantum systems [PDF]
Quantum, 2022 We introduce new methods and tools to study and characterise classical and quantum correlations emerging from prepare-and-measure experiments with informationally restricted communication.

Device-independent randomness generation with sublinear shared quantum resources [PDF]
Quantum, 2018 In quantum cryptography, device-independent (DI) protocols can be certified secure without requiring assumptions about the inner workings of the devices used to perform the protocol.
