Robust Genuine Multipartite Entanglement in Two Walker Quantum Walks
Sandipan Hazra, Tamoghna Das, Sougato Bose +1
Discrete-time quantum walks provide a versatile framework for investigating the generation, redistribution, and transport of quantum correlations in composite quantum systems. Here…
Security of deterministic key distribution with higher-dimensional systems
Abhishek Muhuri, Ayan Patra, Rivu Gupta +2
We analyze the security of two-way quantum key distribution using arbitrary finite-dimensional systems, considering both individual and collective eavesdropping attacks, without th…
"Nonlocality-of-a-single-photon" based Quantum Key Distribution and Random Number Generation schemes and their device-independent security analysis
Konrad Schlichtholz, Bianka Woloncewicz, Tamoghna Das +2
The question of ``non-locality of a single photon'', which started with a paper by Tan, Walls and Collett (TWC, 1991) stirred a thirty years long debate. This hampered attempts to…
Dimensional advantage in secure information trading via the noisy dense coding protocol
Ayan Patra, Rivu Gupta, Tamoghna Das +1
The quantum dense coding (DC) protocol, which has no security feature, deals with the transmission of classical information encoded in a quantum state by using shared entanglement…
Quantum illumination with a light absorbing target
Rivu Gupta, Saptarshi Roy, Tamoghna Das +1
In a quantum illumination (QI) protocol, the task is to detect the presence of the target which is typically modelled by a partially reflecting beam splitter. We analyze the perfor…
Localizing genuine multimode entanglement: Asymmetric gains via non-Gaussianity
Ratul Banerjee, Saptarshi Roy, Tamoghna Das +1
Measurement-based quantum correlation mimics several characteristics of multipartite quantum correlations and at the same time, it reduces the parent system to a smaller subsystem.…
