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…
Compass state: Effect of squeezing and displacement on the Fock space
Arman, Prasanta K. Panigrahi
We investigate a broad class of non-classical states, composed of superposed squeezed and displaced number states. The phase space structure is analysed, keeping in mind, Heisenber…
Sensing Single Photon in a Cat State
Arman, Gargi Tyagi, Prasanta K. Panigrahi
The cat state is shown to `store' a single photon through the superposition of its orthogonal counterpart with itself, and an excited oscillator state. Photon addition leads to a $…
