Entanglement-enhanced fluctuation-free daemonic ergotropy with random measurements
Saptarshi Roy, Pritam Halder, Tamal Guha +1
Optimized daemonic ergotropy can make entanglement thermodynamically dispensable in measurement-assisted work extraction: for a fixed system marginal, quantum-classical states can…
Role of quantum state texture in probing resource theories and quantum phase transition
Ayan Patra, Tanoy Kanti Konar, Pritam Halder +1
Building on the recently developed quantum state texture resource theory, we exhibit that the difference between maximum and minimum textures is a valid purity monotone in any dime…
Revealing effects of local dimension on variable-range interacting model by connecting Lieb-Robinson bounds and multipartite entanglement
Keshav Das Agarwal, Debkanta Ghosh, Pritam Halder +1
A spin- variable-range interacting Ising model may display qualitatively different behaviors depending on the fall-off rate of the interactions, as already seen in equilibrium s…
Classical capacities under physical constraints: More capacity with less entanglement
Sudipta Mondal, Pritam Halder, Saptarshi Roy +1
Current advancements in communication equipment demand the investigation of classical information transfer over quantum channels, by encompassing realistic scenarios in finite dime…
Efficient formulation of quantum network under amplitude damping noise: Highlighting benefits over its Pauli-twirled counterpart
Sudipta Mondal, Pritam Halder, Stav Haldar +1
At the heart of building a large-scale quantum internet lies the challenge of establishing long-distance entanglement using quantum repeaters, which mitigate direct transmission lo…
Indefinite Time Directed Quantum Metrology
Gaurang Agrawal, Pritam Halder, Aditi Sen De
We explore the performance of the metrology scheme by employing a quantum time flip during encoding, a specific case of processes with indefinite time direction, which we refer to…
