Qubit magic-breaking channels
Ayan Patra, Rivu Gupta, Alessandro Ferraro +1
We develop a notion of quantum channels that can make states useless for universal quantum computation by destroying their magic (non-stabilizerness) - we refer to them as magic-br…

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…

Performance of Dense Coding and Teleportation for Random States --Augmentation via Pre-processing
Rivu Gupta, Shashank Gupta, Shiladitya Mal +1
In order to understand the resourcefulness of a natural quantum system in quantum communication tasks, we study the dense coding capacity (DCC) and teleportation fidelity (TF) of H…
