Real-time simulations of transmon systems with time-dependent Hamiltonian models
Hannes Lagemann
In this thesis we study aspects of Hamiltonian models which can affect the time evolution of transmon systems. We model the time evolution of various systems as a unitary real-time…
On the fragility of gate-error metrics in simulation models of flux-tunable transmon quantum computers
Hannes Lagemann, Dennis Willsch, Madita Willsch +3
Constructing a quantum computer requires immensely precise control over a quantum system. A lack of precision is often quantified by gate-error metrics, such as the average infidel…
Random State Technology
Fengping Jin, Dennis Willsch, Madita Willsch +3
We review and extend, in a self-contained way, the mathematical foundations of numerical simulation methods that are based on the use of random states. The power and versatility of…
Benchmarking Supercomputers with the Jülich Universal Quantum Computer Simulator
Dennis Willsch, Hannes Lagemann, Madita Willsch +3
We use a massively parallel simulator of a universal quantum computer to benchmark some of the most powerful supercomputers in the world. We find nearly ideal scaling behavior on t…
