Spectral and Impedance Matching for Multi-excitation Charging of an Interacting Quantum Battery via an Anharmonic Mediator
Sujay Mondal, Anumita Mukhopadhyay, Siddhartha Dutta +1
We investigate a finite-time quantum-battery charging architecture in which a driven two-level working system transfers nonequilibrium resources to an interacting two-qubit battery…

Cross-Spectral Reservoir Correlations as a Resource for Finite-Time Quantum Otto Engines
Siddhartha Dutta, Sujay Mondal, Ankush Das +2
We investigate the thermodynamic consequences of longitudinal-transverse cross-spectral reservoir correlations in a finite-time quantum Otto engine with a two-level working medium.…

Estimation of trace distance between two arbitrary quantum states
Sanchita Ghosh, Anumita Mukhopadhyay, Anindita Bera +2
When it comes to discriminating between two quantum states, trace distance is one of the well-known metrics used in quantum computation and quantum information theory. While there…
