Block-encodings as programming abstractions: The Eclipse Qrisp BlockEncoding Interface
Matic PetriÄ, René Zander
Block-encoding is a foundational technique in modern quantum algorithms, enabling the implementation of non-unitary operations by embedding them into larger unitary matrices. While…

Role of Riemannian geometry in double-bracket quantum imaginary-time evolution
René Zander, Raphael Seidel, Li Xiaoyue +1
Double-bracket quantum imaginary-time evolution (DB-QITE) is a quantum algorithm which coherently implements steps in the Riemannian steepest-descent direction for the energy cost…

A parameter study for LLL and BKZ with application to shortest vector problems
Tobias Köppl, René Zander, Louis Henkel +1
In this work, we study the solution of shortest vector problems (SVPs) arising in terms of learning with error problems (LWEs). LWEs are linear systems of equations over a modular…
