Neutrino oscillation is deemed as an interesting physical phenomenon and shows the
nonclassical features made apparently by the Leggett–Garg inequality. The uncertainty …

Neutrino oscillation is an important physical phenomenon in elementary particle physics,
and its nonclassical features can be revealed by the Leggett–Garg inequality. It shows that …

It was shown that the particle distribution detected by a uniformly accelerated observer in the
inertial vacuum (Unruh effect) deviates from the pure Planckian spectrum when considering …

Quantum correlations provide a fertile testing ground for investigating fundamental aspects
of quantum physics in various systems, especially in the case of relativistic (elementary) …

Quantum complexity is emerging as a key property of many-body systems, including black
holes, topological materials, and early quantum computers. A state's complexity quantifies …

We find the entanglement entropy of a subregion of the vacuum state in scalar quantum
electrodynamics, working perturbatively to the two-loop level. Doing so leads us to derive …

Leggett–Garg inequality (LGI) is a time analogue of Bell's inequality that concerns
measurements performed on a system at different times. Violation to LGI indicates quantum …

Quantum information theory has recently emerged as a flourishing area of research and
quantum complexity, one of its powerful measures, is being applied for investigating …

Abstract The violation of Leggett–Garg inequalities tested the quantumness of neutrino
oscillations (NOs) across macroscopic distances. The quantumness can be quantified by …

The two flavor neutrinos are mapped to quantum bit states used in quantum information
theory. Such qubits of the neutrino state can be encoded on a IBMQ computer using …
