Bosonic Diffusive Channel: Quantum Metrology via Finite Non-Gaussian Resource
Arman, Prasanta K. Panigrahi
We investigate the estimation of dephasing-induced decoherence in continuous-variable quantum systems using non-Gaussian probe states. By purifying the open system, we identify opt…

Enhancing the Size of Phase-Space States Containing Sub-Planck-Scale Structures via Non-Gaussian Operations
Arman, Prasanta K. Panigrahi
We observe a metrological advantage in phase-space sensitivity for photon-added cat and kitten states over their original forms, due to phase-space broadening from increased amplit…

Optimal sensing of photon addition and subtraction on nonclassical light
Soumyabrata Paul, Arman, S. Lakshmibala +3
We demonstrate that the Wasserstein distance corresponding to optical tomograms of nonclassical states faithfully captures changes that arise due to photon addition to, or…
