Negativity of Wigner distribution function as a measure of incompatibility
Jatin Ghai, Gautam Sharma, Sibasish Ghosh
Measurement incompatibility and the negativity of quasiprobability distribution functions are well-known non-classical aspects of quantum systems. Both of them are widely accepted…
Characterizing the generalized complementarity polytope with extractable information from MUBs
Gautam Sharma
Complementarity polytope is a geometric structure that exists in N2-1 dimensional space for an N dimensional Hilbert space. The existence of N + 1 mutually unbiased bases(MUBs) is…
A geometric way to find the measures of uncertainty from statistical divergences for discrete and finite probability distributions
Gautam Sharma, Sk Sazim
Exploiting the geometric nature of statistical divergences, we devise a way to define associated induced uncertainty measures for discrete and finite probability distributions. We…
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…
Robustness of interferometric complementarity under Decoherence
Gautam Sharma, Mohd Asad Siddiqui, Shiladitya Mal +2
Interferometric complementarity is known to be one of the most nonclassical manifestations of the quantum formalism. It is commonly known as wave-particle duality and has been stud…
Quantum Coherence, Coherent Information and Information Gain in Quantum Measurement
Gautam Sharma, Sk Sazim, Arun Kumar Pati
A measurement is deemed successful, if one can maximize the information gain by the measurement apparatus. Here, we ask if quantum coherence of the system imposes a limitation on t…
