Financial Contagion Networks as Annealing-Ready Ising Systems Cascades, Bailout Optimization, and Susceptibility
Abhinav Tomar, Lakshya Nagpal, Vikas Chauhan +1
Interconnected financial systems are vulnerable to cascading failures arising from cross-holdings and nonlinear contagion, making the analysis and mitigation of systemic risk a cha…
A Geometric Theory of Fermion-to-Qubit Encodings
Lakshya Nagpal, Nishith Reen, S. R. Hassan
Exact fermion to qubit transformations are conventionally regarded as algorithmic tools that translate many-body Hamiltonians into qubit representations for quantum simulation. Her…
Worldline-Susceptibility Scheduling for Quantum Annealing Beyond Local-Adiabatic Evolution
Suraj Singh, Lakshya Nagpal, Vikas Chauhan +1
The performance of quantum annealing depends critically on how the available annealing time is distributed along the evolution. Although the Roland Cerf local adiabatic schedule is…
Adaptive Quantum Matter: Variational Organization through Ising Agents
Lakshya Nagpal, Syed. R. Hassan
The study introduces the Adaptive Quantum Ising Agents (AQIA) framework, a Hamiltonian-based methodology that extends programmable quantum matter into an adaptive domain. Each agen…
Beating the standard quantum limit with single-photon-added coherent states
Pankaj K. Jha, Lakshya Nagpal, Amir Targholizadeh +2
The standard quantum limit (SQL), also known as the shot-noise limit, defines how quantum fluctuations of light constrain measurement precision. In a benchmark experiment using the…
Mapping of Fermionic Lattice Models for Ising Solvers
Lakshya Nagpal, Aditya Kumar, S. R. Hassan
We present an end-to-end, symmetry-aware pipeline that converts interacting fermionic and quantum-spin models into annealer-ready QUBOs while preserving low-energy physics. The wor…
