Q-SPARSE: Quantum Subspace Projection for Near-Field Angle-Range Spectrum Estimation

Near-field wavefront curvature enables joint angle-range localization, but exploiting it entails repeated covariance-eigenspace tests over a two-dimensional spherical manifold. We propose a quantum subspace-projection algorithm (Q-SPARSE) for super-resolution estimation of parameters in the near field, employing spectr...

Accelerated quantum-centric supercomputing through perturbation-theoretic measures and generative machine learning

PIGen-SQD is introduced, an efficiently designed QCSC workflow that utilizes the capability of generative machine learning (ML) along with physics-informed configuration screening via implicit low-rank tensor decompositions for accurate fermionic state reconstruction.
