Induced Coherence in Quantum and Classical Interferometry: Origin and Control
Balakrishnan Viswanathan, Ravi Kamal Pandey, Devendra Kumar Mishra +2
The wave-particle duality that manifests in the Young's double-slit interferometry satisfying the well known Englert-Greenberger-Yasin inequality has recently been shown to obey a…
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…
Persistence of Quantum Triality Relations in Open Qubit and Qutrit Systems
Pratidhwani Swain, Ramita Sarkar, Sukanta K. Tripathy +1
We examine the complementarity among coherence (visibility), predictability, and entanglement for qubit and qutrit systems subjected to noisy quantum channels. Using the system-pat…
Hierarchical QAOA for the Vehicle Routing Problem via Clustered Decomposition and Local Feasibility Repair
Shreetam Dash, Shreya Banerjee, Prasanta K. Panigrahi
We propose a hierarchical quantum approximate optimization framework for solving large-scale Vehicle Routing Problems (VRP) using Quantum Approximate Optimization Algorithm (QAOA).…
Communication through the combination of quantum switch and coherent superposition of channels
Arghyabindu Patra, Abdul Q Batin, Prasanta K. Panigrahi
The quantization of particle trajectories gives rise to remarkable features such as the coherent superposition of quantum channels and the quantum switch, which offer significant a…
