A new error-modeling of Hardy's paradox for superconducting qubits and its experimental verification
Soumya Das, Goutam Paul
Hardy's paradox (equivalently, Hardy's non-locality or Hardy's test) [\href{https://link.aps.org/doi/10.1103/PhysRevLett.68.2981}{L. Hardy, Phys. Rev. Lett. \textbf{68}, 2981 (1992…
A complete characterization of the optimal unitary attacks in quantum cryptography with a refined optimality criteria involving the attackers Hilbert space only
Atanu Acharyya, Goutam Paul
Fuchs et al. [Phys. Rev. A, 1997] suggested an optimal attack on the BB84 protocol, where the necessary and sufficient condition for optimality involves the joint Hilbert space of…
Revisiting Generalized Bertand's Postulate and Prime Gaps
Madhuparna Das, Goutam Paul
It is a well-known fact that for any natural number , there always exists a prime in . Our aim in this note is to generalize this result to . A lower as well a…
Quantum Error Correction using Hypergraph States
Shashanka Balakuntala, Goutam Paul
Graph states have been used for quantum error correction by Schlingemann et al. [Physical Review A 65.1 (2001): 012308]. Hypergraph states [Physical Review A 87.2 (2013): 022311] a…
Quantum Signaling to the Past Using P-CTCS
Soumik Ghosh, Arnab Adhikary, Goutam Paul
Closed Timelike Curves (CTCs) are intriguing relativistic objects that allow for time travel to the past and can be used as computational resources. In Deutschian Closed Timelike C…
Revisiting Integer Factorization using Closed Timelike Curves
Soumik Ghosh, Arnab Adhikary, Goutam Paul
Closed Timelike Curves are relativistically valid objects allowing time travel to the past. Treating them as computational objects opens the door to a wide range of results which c…
