Macroscopic quantum synchronization effects
Tobias Nadolny, Christoph Bruder
We theoretically describe macroscopic quantum synchronization effects occurring in a network of all-to-all coupled quantum limit-cycle oscillators. The coupling causes a transition…
Improving Transmon Qudit Measurement on IBM Quantum Hardware
Tobias Kehrer, Tobias Nadolny, Christoph Bruder
The Hilbert space of a physical qubit typically features more than two energy levels. Using states outside the qubit subspace can provide advantages in quantum computation. To bene…
Mapping out phase diagrams with generative classifiers
Julian Arnold, Frank Schäfer, Alan Edelman +1
One of the central tasks in many-body physics is the determination of phase diagrams. However, mapping out a phase diagram generally requires a great deal of human intuition and un…
Geometric Phase in Quantum Synchronization
Aaron Daniel, Christoph Bruder, Martin Koppenhöfer
We consider a quantum limit-cycle oscillator implemented in a spin system whose quantization axis is slowly rotated. Using a kinematic approach to define geometric phases in nonuni…
