Performance Analysis of Satellite-Based QKD Protocols
Muskan, Ramniwas Meena, Subhashish Banerjee
Satellite-based free-space quantum key distribution (QKD) provides a practical framework for achieving secure global communication beyond the limitations of optical fibers. In this…
Quantum chaos in the Dicke model and its variants
Devvrat Tiwari, Subhashish Banerjee
Recently, the out-of-time-ordered correlator (OTOC) has gained much attention as an indicator of quantum chaos. In the semi-classical limit, its exponential growth rate resembles t…
Impact of non-Markovian evolution on characterizations of quantum thermodynamics
Devvrat Tiwari, Subhashish Banerjee
Here we study the impact of non-Markovian evolution on prominent characteristics of quantum thermodynamics, such as ergotropy and power. These are benchmarked by the behavior of th…
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…
Characterization of Quantumness of non-Gaussian states under the influence of Gaussian channel
Ramniwas Meena, Subhashish Banerjee
The impact of a noisy Gaussian channel on a wide range of non-Gaussian input states is studied in this work. The nonclassical nature of the states, both input and output, is develo…
Thermodynamics of one and two-qubit nonequilibrium heat engines running between squeezed thermal reservoirs
Ashutosh Kumar, Trilochan Bagarti, Sourabh Lahiri +1
Quantum heat engines form an active field of research due to their potential applications. There are several phenomena that are unique to the quantum regime, some of which are know…
