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…
