Macrorealistic inequalities stronger than the standard Leggett-Garg inequalities
Swati Kumari, A. K. Pan
In two-party, two-input and two-output measurement scenario only relevant Bell's inequality is the Clauser-Horne-Shimony-Holt (CHSH) form. They also provide the necessary and suffi…
symmetric evolution, coherence and violation of Leggett-Garg inequalities
Javid Naikoo, Swati Kumari, A. K. Pan +1
We report an unusual buildup of the quantum coherence in a qubit subjected to non-Hermitian evolution generated by a Parity-Time () symmetric Hamiltonian, which is re…
Probing inequivalent forms of Legget-Garg inequality in subatomic systems
Javid Naikoo, Swati Kumari, Subhashish Banerjee +1
We study various formulations of Leggett-Garg inequality (LGI), specifically, the Wigner and Clauser-Horne forms of LGI, in the context of subatomic systems, in particular, three f…
Quantum violation of variants of LGIs upto algebraic maximum for qubit system
A. K. Pan, Md. Qutubuddin, Swati Kumari
In 1985, Leggett and Garg formulated a class of inequalities for testing the compatibility between macrorealism and quantum mechanics. In this paper, we point out that based on the…
Inequivalent Leggett-Garg inequalities
Swati Kumari, A. K. Pan
It remains an open question how realist view of macroscopic world emerges from quantum formalism. For testing the macrorealism in quantum domain, an interesting approach was put fo…
Probing various formulations of macrorealism for unsharp quantum measurements
Swati Kumari, A. K. Pan
Standard Leggett and Garg inequalities (SLGIs) were formulated for testing the incompatibility between the classical worldview of macrorealism and quantum mechanics. In recent time…
