Quantum algorithms with local particle number conservation: noise effects and error correction
Michael Streif, Martin Leib, Filip Wudarski +2
Quantum circuits with local particle number conservation (LPNC) restrict the quantum computation to a subspace of the Hilbert space of the qubit register. In a noiseless or fault-t…
Forbidden subspaces for level-1 QAOA and IQP circuits
Michael Streif, Martin Leib
We present a thorough investigation of problems that can be solved exactly with the level-1 Quantum Approximate Optimization Algorithm (QAOA). To this end we implicitly define a cl…
Quantum Approximate Optimization of Non-Planar Graph Problems on a Planar Superconducting Processor
Matthew P. Harrigan, Kevin J. Sung, Matthew Neeley +83
We demonstrate the application of the Google Sycamore superconducting qubit quantum processor to combinatorial optimization problems with the quantum approximate optimization algor…
Training the Quantum Approximate Optimization Algorithm without access to a Quantum Processing Unit
Michael Streif, Martin Leib
In this paper, we eliminate the classical outer learning loop of the Quantum Approximate Optimization Algorithm (QAOA) and present a strategy to find good parameters for QAOA based…
Comparison of QAOA with Quantum and Simulated Annealing
Michael Streif, Martin Leib
We present a comparison between the Quantum Approximate Optimization Algorithm (QAOA) and two widely studied competing methods, Quantum Annealing (QA) and Simulated Annealing (SA).…
Solving Quantum Chemistry Problems with a D-Wave Quantum Annealer
Michael Streif, Florian Neukart, Martin Leib
Quantum annealing devices have been subject to various analyses in order to classify their usefulness for practical applications. While it has been successfully proven that such sy…
