In this letter, we present a new nonorthogonal algorithm for joint diagonalization of a set of symmetric matrices. The algorithm alternates between updates of individual demixing matrix rows, and the ...

Japan hosts the world’s most powerful quantum–classical setup with IBM’s Heron processor and Fugaku supercomputer.

In this report, we propose a novel quantum diagonalization algorithm through optimizing a variational quantum circuit. The optimization process utilizes measurement outcomes in the computational basis ...

kitaev_clusters: Python package for Exact Diagonalization of the Kitaev honeycomb model. Efficient construction and diagonalization of extremely large sparse matrix Hamiltonians ...

Various real-space methods optimized on massive parallel computers have been developed for efficient large-scale density functional theory (DFT) calculations of materials and biomolecules. The ...

When the size of system grows sufficiently or processing cores have a relevant scale, fitted scaling turns back to O (N3) due to the cubic scaling of conventional diagonalization step. As a conclusion ...
