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…
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…
Measurement-based quantum computation with variable-range interacting systems
Debkanta Ghosh, Keshav Das Agarwal, Pritam Halder +1
We demonstrate that weighted graph states (WGS) generated via variable-range interacting Ising spin systems where the interaction strength decays with distance as a power law, char…
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…
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…
More nonlocality with less incompatibility in higher dimensions: Bell vs prepare-measure scenarios
Sudipta Mondal, Pritam Halder, Saptarshi Roy +1
Connecting incompatibility in measurements with the violation of local realism is one of the fundamental avenues of research. For two qubits, any incompatible pair of projective me…
