Imaginarity-generating power of unitaries: A resource-theoretic approach
Akhil Kumar Awasthi, Mrinmoy Samanta, Sudipta Mondal +2
Imaginarity, stemming from the complex structure of quantum mechanics, has recently emerged as a fundamental resource, yet its dynamical generation remains largely unexplored. In t…
Hierarchies of Gaussian multimode entanglement from thermodynamic quantifiers
Mrinmoy Samanta, Sudipta Mondal, Ayan Patra +2
We develop a thermodynamic characterization of multimode entanglement in pure continuous-variable systems by quantifying the gap between globally and locally extractable work (ergo…
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…
Hierarchy of entanglement detection criteria for random high-dimensional states
Akhil Kumar Awasthi, Sudipta Mondal, Rivu Gupta +1
Entanglement is a cornerstone in quantum information science, yet detecting it efficiently remains a challenging task. Focusing on non-positive partially transposed (NPT) states, w…
Disparity between multipartite entangling and disentangling powers of unitaries: Even vs Odd
Mrinmoy Samanta, Sudipta Mondal, Aditi Sen De
We compare the multipartite entangling and disentangling powers of unitary operators by assessing their ability to generate or eliminate genuine multipartite entanglement. Our find…
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…
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…
Recovery of resources through sequential noisy measurements
Sudipta Mondal, Pritam Halder, Amit Kumar Pal +1
Noisy unsharp measurements incorporated in quantum information protocols may hinder performance, reducing the quantum advantage. However, we show that, unlike projective measuremen…
Imperfect Entangling Power of Quantum Gates
Sudipta Mondal, Samir Kumar Hazra, Aditi Sen De
Achieving perfect control over the parameters defining a quantum gate is, in general, a very challenging task, and at the same time, environmental interactions can introduce distur…
Hierarchies among genuine multipartite entangling capabilities of quantum gates
Mrinmoy Samanta, Sudipta Mondal, Samir Kumar Hazra +1
We classify quantum gates according to their capability to generate genuine multipartite entanglement (GME), using a hierarchy based on multipartite separable states. In particular…
