General Bayesian theories and the emergence of the exclusivity principle
(American Physical Society, 2020-10-05)
We address the problem of reconstructing quantum theory from the perspective of an agent who makes bets about the outcomes of possible experiments. We build a general Bayesian framework that can be used to organize the ...

A new numerical approach for efficient modeling of positive corona discharge and its associated electric wind
(IOP Publishing, 2023)
Research on corona wind generation has been increasing in recent years because of its potential technological applications, particularly those related to improving heat transfer in small-scale devices. Since numerical ...

Classical Physics and the Bounds of Quantum Correlations
(American Physical Society, 2016-06-24)
A unifying principle explaining the numerical bounds of quantum correlations remains elusive, despite the efforts devoted to identifying it. Here, we show that these bounds are indeed not exclusive to quantum theory: for ...

Converting contextuality into nonlocality
(American Physical Society, 2021-08)
We introduce a general method which converts, in a unified way, any form of quantum contextuality, including any form of state-dependent contextuality, into a quantum violation of a bipartite Bell inequality. As an example, ...

Electron-pair entropic and complexity measures in atomic systems
(Wiley, 2019)
The two-electron atomic densities are analysed in both position and momentum spaces in terms of different information-theoretic measures, such as disequilibrium, Shannon entropy, shape complexity and its corresponding ...

Tracking the dynamics of an ideal quantum measurement
(American Physical Society, 2020-02-25)
The existence of ideal quantum measurements is one of the fundamental predictions of quantum mechanics. In theory, an ideal measurement projects a quantum state onto the eigenbasis of the measurement observable, while ...

Bell non-locality and Kochen-Specker contextuality: how are they connected?
(Springer, 2021-05-22)
Bell non-locality and Kochen–Specker (KS) contextuality are logically independent concepts, fuel different protocols with quantum vs classical advantage, and have distinct classical simulation costs. A natural question is ...

Chiral spin channels in curved graphene pn junctions
(American Physical Society, 2023-09-20)
We show that the chiral modes in circular graphene pn junctions provide an advantage for spin manipulation via spin-orbit coupling compared to semiconductor platforms. We derive the effective Hamiltonian for the spin ...

Quantum correlations from simple assumptions
(American Physical Society, 2019-09-24)
We address the problem of deriving the set of quantum correlations for every Bell and Kochen-Specker (KS) contextuality scenario from simple assumptions. We show that the correlations that are possible according to quantum ...

Device-independent certification of two bits of randomness from one entangled bit and Gisin's elegant Bell inequality
(American Physical Society, 2018-01-16)
We prove that as conjectured by Acín et al. [Phys. Rev. A 93, 040102(R) (2016)], two bits of randomness can be certified in a device-independent way from one bit of entanglement using the maximal quantum violation of Gisin’s ...
