Quantum Adiabatic Brachistochrone
A. T. Rezakhani, W. -J. Kuo, A. Hamma +2
We formulate a time-optimal approach to adiabatic quantum computation (AQC). A corresponding natural Riemannian metric is also derived, through which AQC can be understood as the p…
Scaling of the fidelity susceptibility in a disordered quantum spin chain
N. Tobias Jacobson, Silvano Garnerone, Stephan Haas +1
The phase diagram of a quantum XY spin chain with Gaussian-distributed random anisotropies and transverse fields is investigated, with focus on the fidelity susceptibility, a recen…
Fidelity in topological quantum phases of matter
Silvano Garnerone, Damian Abasto, Stephan Haas +1
Quantum phase transitions that take place between two distinct topological phases remain an unexplored area for the applicability of the fidelity approach. Here, we apply this meth…
