Basis-independent coherence and quantum correlations in two dipole-dipole-coupled electrons in double quantum-dot molecules
Zakaria Bouafia, Neha Pathania, Mostafa Mansour
This work examines the thermal dynamics of basis-independent quantum coherence and correlation-based quantum resources for two dipole-dipole-coupled electrons confined in spatially…
Finite key analysis of experimentally realized practical COW-QKD protocol
Neha Pathania, Sandeep Mishra, Anirban Pathak
An experimental implementation of the Coherent One-Way Quantum Key Distribution (COW-QKD) protocol is reported under realistic conditions, and a clean and easy-to-use framework for…
Quantum Thermodynamics of Open Quantum Systems: Nature of Thermal Fluctuations
Neha Pathania, Devvrat Tiwari, Subhashish Banerjee
We investigate the thermodynamic behavior of open quantum systems through the Hamiltonian of Mean Force, focusing on two models: a two-qubit system interacting with a thermal bath…
Coherence, Path-Predictability and I-Concurrence: A Triality
Abhinash Kumar Roy, Neha Pathania, Nitish Kumar Chandra +2
It is well known that fringe contrast is not a good quantifier of the wave nature of a quanton in multipath interference. A new interference visibility, based on the Hilbert-Schmid…
Quantifying Entanglement with Coherence
Neha Pathania, Tabish Qureshi
Quantifying entanglement is a work in progress which is important for the active field of quantum information and computation. A measure of bipartite pure state entanglement is pro…
Dynamics of Quantum Coherence and Non-Classical Correlations in Open Quantum System Coupled to a Squeezed Thermal Bath
Neha Pathania, Ramniwas Meena, Subhashish Banerjee
We investigate the intricate dynamics of quantum coherence and non-classical correlations in a two-qubit open quantum system coupled to a squeezed thermal reservoir. By exploring t…
