Information leak and incompatibility of physical context: A modified approach
Arindam Mitra, Gautam Sharma, Sibasish Ghosh
A beautiful idea about the incompatibility of Physical Context(IPC) was introduced in Phys. Rev. A 102, 050201(R) (2020). Here, a context is defined as a set of a quantum state and…

Layers of classicality in the compatibility of measurements
Arindam Mitra
The term "Layers of classicality" in the context of quantum measurements, was introduced in [T. Heinosaari, Phys. Rev. A 93, 042118 (2016)]. The strongest layer among these consist…

Characterizing incompatibility of quantum measurements via their Naimark extensions
Arindam Mitra, Sibasish Ghosh, Prabha Mandayam
We obtain a formal characterization of the compatibility or otherwise of a set of positive-operator-valued measures (POVMs) via their Naimark extensions. We show that a set of POVM…
