In this work we study temporal quantum correlations, quantified by Leggett-Garg (LG) and
LG-type inequalities, in the B and K meson systems. We use the tools of open quantum …

We propose a scheme for dissipative preparation of maximal entanglement in a two-qubit
Heisenberg XXZ model interacting asymmetrically with two independent boson thermal …

We study the steady-state entanglement and correlations of an open system comprising two
coupled fermions in the equilibrium or nonequilibrium environments and distill the …

Einstein-Podolsky-Rosen steering describes a quantum correlation in addition to
entanglement and Bell nonlocality. However, conceptually different from entanglement and …

We study some aspects of the Leggett-Garg inequalities by using the operator-state
formalism for multitime processes. The process tensor in its Choi-state form, which we call …

In the present paper we introduce a way of identifying quantum phase transitions of many-
body systems by means of local time correlations and Leggett-Garg inequalities. This …

Macrorealism formalizes the seemingly intuitive notion that, in contrast with the principles of
quantum mechanics, a physical system can be in a definite state at any given time and …

Even photosynthesis—the most basic natural phenomenon underlying life on Earth—
involves the nontrivial processing of excitations at the pico‐and femtosecond scales during …

We study the macroscopic realism (macrorealism) through the two-and three-time Leggett-
Garg inequalities (LGIs) in a two-interacting-qubits system. The two qubits are coupled either …

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 …
