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).…
Concurrence fill and mode distribution of entanglement in neutrino oscillation
Rajrupa Banerjee, Prasanta K. Panigrahi, Hiranmaya Mishra +1
In the framework of three flavor neutrino oscillation, we demonstrate that the measures of entanglement can be expressed in terms of experimentally accessible appearance and disapp…
Data-Driven Linearization based Arc Fault Prediction in Medium Voltage Electrical Distribution System
Mihir Sinha, Kriti Thakur, Prasanta K. Panigrahi +2
High-impedance arc faults (HIAFs) in medium-voltage electrical distribution systems are difficult to detect due to their low fault current levels and nonlinear transient behavior.…
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…
Wave-particle duality and entanglement in neutrino oscillation
Rajrupa Banerjee, Pratidhwani Swain, Prasanta K. Panigrahi +1
We investigate wave--particle--entanglement complementarity in three-flavor neutrino oscillations within a quantum information--theoretic framework. Treating neutrino flavor evolut…
