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…
Bounds on concatenated entanglement-assisted quantum error-correcting codes
Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1
Code concatenation combines two or more component codes to design larger codes with greater noise resilience. Introducing entanglement assistance to concatenated codes provides a f…
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…
Non-Markovianity in Discrete-Time Open Quantum Random Walk on Arbitrary Graphs
Monika Rani, Supriyo Dutta, Subhashish Banerjee
In this work, we present a new model of the Discrete-Time Open Quantum Walk (DTOQW) applicable to an arbitrary graph, thereby going beyond the case of quantum walks on regular grap…
Exploring the Non-Markovian Dynamics in Depolarizing Maps
Ali Abu-Nada, Subhashish Banerjee, Vivek Balasaheb Sabale
The non-Markovian depolarizing channel is explored from the perspective of understanding its non-Markovian behavior as well as the occurrence of singularities. The study brings tog…
Continuous Variable Based Quantum Communication in the Ocean
Ramniwas Meena, Subhashish Banerjee
Continuous Variable-Based Quantum Cryptography (CV-QKD) is an emerging field in quantum information science, offering unprecedented security for communication protocols by harnessi…
Facets of correlated non-Markovian channels
Vivek Balasaheb Sabale, Nihar Ranjan Dash, Atul Kumar +1
We investigate the domain of correlated non-Markovian channels, exploring the potential memory arising from the correlated action of channels and the inherent memory due to non-Mar…
