Noncontextual wirings
(American Physical Society, 2018-03-29)
Contextuality is a fundamental feature of quantum theory necessary for certain models of quantum computation and communication. Serious steps have therefore been taken towards a formal framework for contextuality as an ...

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, ...

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 ...

Graph-theoretic approach to dimension witnessing
(IOP Publishing, 2021-03)
A fundamental problem in quantum computation and quantum information is finding the minimum quantum dimension needed for a task. For tasks involving state preparation and measurements, this problem can be addressed using ...

Quantum contextuality provides communication complexity advantage
(American Physical Society, 2023-02-24)
Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement. Here, we show that for any quantum state and observables ...
