Deterministic Quantum Jump (DQJ) Method for Weakly Dissipative Systems
Marcus Meschede, Ludwig Mathey
Physical quantum systems are generically coupled to an environment, resulting in open system dynamics. A typical approach to simulating this dynamics is to propagate the density ma…

Eigen-SNAP gate for photonic qubits in a cavity-transmon system
Marcus Meschede, Ludwig Mathey
In the pursuit of robust quantum computing, we put forth a platform based on photonic qubits in a circuit-QED environment. Specifically, we propose a versatile two-qubit gate based…

Drive-induced Non-local Interactions and Topological Bulk Transport of Extended Doublons
Julius Beck, Matthias Heinrich, Marcus J. Meschede +6
The existence of boundary states and their protection against symmetry-preserving perturbations are a hallmark feature of topological systems. While this concept originally emerged…
