Backward errorThe contour integral-based eigensolvers have attracted much attention in recent years. In this paper, we consider solving a polynomial eigenvalue problem (PEP) by a contour integral-based eigensolver named the Sakurai-Sugiura method with Rayleigh-Ritz projection (SS-RR method). We ...

Is there any news on the implementation of sparse eigensolvers for smallest eigenvalues? Currently, jax.experimental.sparse.linalg.lobpcg_standard seems to only support largest eigenvalues. Thanks! Just run LOBPCG for -A where A is the matrix of the eigenvalue problem and multiply the largest ...
we propose a full quantum generalized eigensolver (FQGE) to calculate the minimal generalized eigenvalue with quantum gradient descent algorithm. As a demonstration of the principle, we numerically implement our algorithms to conduct a 2-qubit simulation and successfully find the generalized eigenvalues...
