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…
Hierarchies for Semidefinite Optimization in -Algebras
Gereon Koßmann, René Schwonnek, Jonathan Steinberg
Semidefinite Optimization has become a standard technique in the landscape of Mathematical Programming that has many applications in finite dimensional Quantum Information Theory.…
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…
