Discrete and Continuous Wigner Functions in Open Quantum Systems: Non-Markovian and Thermodynamic Effects

Jai Lalita

The central aim of the thesis is to examine how non-classical resources in finite-dimensional quantum systems can be identified, characterized, and protected for practical use in t…

Interrelation of Non-Classicality, Entropy, Irreversibility and Work extraction in Open Quantum Systems

Jai Lalita, Subhashish Banerjee

The interplay of non-classical volume, von Neumann entropy, entropy production, and ergotropy is investigated in various open quantum systems. Two categories of open quantum system…

Non-classicality of two-qubit quantum collision model: non-Markovian effects

Jai Lalita, Subhashish Banerjee

We investigate a two-qubit quantum system in contact with an environment modeled by a microscopic collision model with added ancilla-ancilla collisions in the non-Markovian regime.…

Realizing Negative Quantum States with the IBM Quantum Hardware

Jai Lalita, Pavithran Iyer, Subhashish Banerjee

This study explores robust entangled states described using the framework of discrete Wigner functions. Notably, these states are known to outperform the Bell state in measures of…

Protecting quantum correlations of negative quantum states using weak measurement under non-Markovian noise

Jai Lalita, Subhashish Banerjee

The weak measurement (WM) and quantum measurement reversal (QMR) are crucial in protecting the collapse of quantum states. The idea of WM and QMR has recently been used to protect…

Harnessing quantumness of states using discrete Wigner functions under (non)-Markovian quantum channels

Jai Lalita, K. G. Paulson, Subhashish Banerjee

The negativity of the discrete Wigner functions (DWFs) is a measure of non-classicality and is often used to quantify the degree of quantum coherence in a system. The study of Wign…
