This paper points out the importance of the assumption of locality of physical interactions,
and the concomitant necessity of propagation of an entity (in this case, off-shell quanta …

Standard Leggett-Garg inequalities (SLGIs) were formulated for testing incompatibility
between the classical world view of macrorealism and quantum mechanics. In recent times …

In this paper, we consider a qubit in four scenarios: with drive, without drive, and in the
presence of dissipation and dephasing, to investigate the quantum violation of the Leggett …

In this paper, we investigate the violation of the quantum witness, the entropic Leggett–Garg
inequality (LGI) and the no-coherence-generating-and-detecting (NCGD) dynamics, under …

Conservation principles are essential to describe and quantify dynamical processes in all
areas of physics. Classically, a conservation law holds because the description of reality can …

The departure of the quantum world from the classical regime is captured through the
observation of nonclassical correlations manifested in the behaviors of subatomic systems …

Nonclassicality of temporal correlations pertaining to noncommutative sequential
measurements is defined through the violation of macrorealistic inequalities, known as …

In this paper, we investigate the Leggett–Garg inequality (LGI), the Wigner form of Leggett–
Garg inequality (WLGI) and the no-signaling-in-time (NSIT) condition under projective and …

We propose a Wigner-like inequality suitable for testing the hypothesis of realism. We show
that this inequality is identical neither to the well-known Wigner inequality nor to the Leggett …

Abstract The Leggett–Garg inequality (LGI) is used to test incompatibility between the
classical world view of macrorealism and quantum mechanics. Except for the LGI, other …
