Spread complexity for measurement-induced non-unitary dynamics and Zeno effect
Journal of High Energy PhysicsUsing spread complexity and spread entropy, we study non-unitary quantum dynamics. For non-hermitian Hamiltonians, we extend the bi-Lanczos construction for the Krylov basis to the Schrödinger picture.

A modified block Lanczos algorithm with fewer vectors
CoRR, 2016 The block Lanczos algorithm proposed by Peter Montgomery is an efficient means to tackle the sparse linear algebra problem which arises in the context of the number field sieve factoring algorithm and its predecessors. We present here a modified version of the algorithm, which incorporates several improvements: we discuss how to efficiently handle ...

A quantum computational perspective on spread complexity
Physics Letters BWe establish a direct connection between spread complexity and quantum circuit complexity by demonstrating that spread complexity emerges as a limiting case of a circuit complexity framework built from two fundamental operations: time-evolution and ...
