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…
Quantum Backtracking in Qrisp Applied to Sudoku Problems
Raphael Seidel, René Zander, Matic PetriÄ +4
The quantum backtracking algorithm proposed by Ashley Montanaro raised considerable interest, as it provides a quantum speed-up for a large class of classical optimization algorith…
Solving the Product Breakdown Structure Problem with constrained QAOA
René Zander, Raphael Seidel, Matteo Inajetovic +2
Constrained optimization problems, where not all possible variable assignments are feasible solutions, comprise numerous practically relevant optimization problems such as the Trav…
Qrisp: A Framework for Compilable High-Level Programming of Gate-Based Quantum Computers
Raphael Seidel, Sebastian Bock, René Zander +4
While significant progress has been made on the hardware side of quantum computing, support for high-level quantum programming abstractions remains underdeveloped compared to class…
