Leggett and Garg formulated macrorealist models encoding our intuition on classical
systems, ie, physical quantities have a definite value that can be measured with minimal …

We theoretically formulate and experimentally demonstrate a secure scheme for semi-
device-independent quantum random number generation by utilizing Leggett-Garg …

Quantum channels breaking entanglement, incompatibility, or nonlocality are defined as
such because they are not useful for entanglement-based, one-sided device-independent …

The search for empirical schemes to evidence the nonclassicality of large masses is a
central quest of current research. However, practical schemes to witness the irreducible …

We study the Leggett-Garg inequality (LGI) of a two-level system (TLS) undergoing coherent
dynamics described by a non-Hermitian Hamiltonian and Lindblad equation with no …

Macrorealism (MR) is the worldview that certain quantities may take definite values at all
times irrespective of past or future measurements and may be experimentally falsified via the …

The interplay between thermal machines and quantum correlations is of great interest in
both quantum thermodynamics and quantum information science. Recently, a quantum …

Search for empirical schemes to evidence the nonclassicality of large masses is a central
quest of current research. However, practical schemes to witness the irreducible …

Quantum mechanics has always proven emphatically as one of the main cornerstones in all
of science since its inception. Initially, it has also faced many skeptics from many scientific …

I study several aspects of tests of macrorealism (MR), which for a given data set serves to
give a quantitative signal of the presence of a specific notion of non-classical behaviour. The …
