Tensorized Pauli decomposition algorithm
Lukas Hantzko, Lennart Binkowski, Sabhyata Gupta
This paper introduces a novel general-purpose algorithm for Pauli decomposition that employs matrix slicing and addition rather than expensive matrix multiplication, significantly…
A quantum algorithm for solving 0-1 Knapsack problems
Sören Wilkening, Andreea-Iulia Lefterovici, Lennart Binkowski +3
Here we present two novel contributions for achieving quantum advantage in solving difficult optimisation problems, both in theory and foreseeable practice. (1) We introduce the "Q…
From barren plateaus through fertile valleys: Conic extensions of parameterised quantum circuits
Lennart Binkowski, Gereon Koßmann, Tobias J. Osborne +2
Optimisation via parameterised quantum circuits is the prevalent technique of near-term quantum algorithms. However, the omnipresent phenomenon of barren plateaus - parameter regio…
Elementary Proof of QAOA Convergence
Lennart Binkowski, Gereon Koßmann, Timo Ziegler +1
The Quantum Alternating Operator Ansatz (QAOA) and its predecessor, the Quantum Approximate Optimization Algorithm, are one of the most widely used quantum algorithms for solving c…
