Monolithic integration of graphene in SiC radiation sensors for harsh-environment applications
(Trans Tech Publications, 2022)
Due to their low leakage current, low noise levels, high thermal conductivity, and potential radiation hardness, SiC devices offer various advantages over Si devices in certain applications. As a result, they are being ...

Loophole-free Bell tests with randomly chosen subsets of measurement settings
(American Physical Society, 2024-02-06)
There are bipartite quantum nonlocal correlations requiring very low detection efficiency to reach the loophole-free regime but that need too many measurement settings to be practical for actual experiments. This leads to ...

The quantum maxima for the basic graphs of exclusivity are not reachable in Bell scenarios
(The Royal Society, 2024)
A necessary condition for the probabilities of a set of events to exhibit Bell nonlocality or Kochen-Specker contextuality is that the graph of exclusivity of the events contains induced odd cycles with five or more vertices, ...

Certifying sets of quantum observables with any full-rank state
(American Physical Society, 2024-04-03)
We show that some sets of quantum observables are unique up to an isometry and have a contextuality witness that attains the same value for any initial state. We prove that these two properties make it possible to certify ...

Experimental post-selection loophole-free time-bin and energy-time nonlocality with integrated photonics
(Optica Publishing Group, 2024-04-20)
Time-bin (TB) and energy-time (ET) entanglements are crucial resources for long-distance quantum information processing. However, their standard implementations suffer from the so-called post-selection loophole that allows ...
