Geometry-controlled correlated electric-field noise in enclosed ion traps from billiard return spectra
Ayush Nadiger
We ask how passive conducting geometry determines the spatial structure of electric-field noise seen by trapped ions. From a boundary-potential covariance and the Dirichlet Green f…

Potential Energy Savings from Quantum Computing-Based Route Optimization
Ayush Nadiger, Adriana Caraeni, Katie Schouten
We investigate the potential of the Quantum Approximate Optimization Algorithm (QAOA) for reducing energy consumption in route planning, a key challenge in logistics due to the NP-…

Randomized-Accelerated FEAST: A Hybrid Approach for Large-Scale Eigenvalue Problems
Ayush Nadiger
We present Randomized-Accelerated FEAST (RA-FEAST), a hybrid algorithm that combines contour-integration-based eigensolvers with randomized numerical linear algebra techniques for…
