Krylov Subspace Method Using Quantum Computing
2021The Krylov subspace algorithm uses iterative methods to solve bulky linear equations. It has a time complexity of O(n2) when run on a classical computing machine. The proposed algorithm has an exponential speedup over the classical algorithm. It takes O(n√k) time complexity when run on a quantum computer, where k is the condition number. In this paper,

Molecular Properties from Quantum Krylov Subspace Diagonalization.
Journal of Chemical Theory and ComputationQuantum Krylov subspace diagonalization is a prominent candidate for early fault-tolerant quantum simulation of many-body and molecular systems, but so far, the focus has been mainly on computing ground-state energies.

Practical Implementation of Krylov Subspace Spectral Methods
Journal of Scientific Computing, 2007Krylov subspace spectral methods have been shown to be high-order accurate in time and more stable than time-stepping methods but also more difficult for an efficient implementation. The author shows how these methods should be used in practical solvers by exploiting the simple structure of differential operators.

Biconjugate direction methods in Krylov subspaces
Journal of Applied and Industrial Mathematics, 2010Summary: The paper addresses the orthogonal and variational properties of a family of iterative algorithms in Krylov subspaces for solving systems of linear algebraic equations with sparse nonsymmetric matrices. A biconjugate residual method, a squared biconjugate residual method, and a stabilized conjugate residual method are proposed and studied ...
