Adiabatic time evolution of highly excited states
Hadi Yarloo, Hua-Chen Zhang, Anne E. B. Nielsen
Adiabatic time evolution of quantum systems is a widely used tool with applications ranging from state preparation through simplifications of computations and topological transform…
Single-shot determination of quantum phases via continuous measurements
Aniket Patra, Lukas F. Buchmann, Felix Motzoi +3
We propose that weak continuous probing may be exploited to determine and define quantum phases of complex many-body systems based on the measurement record alone. We test the resu…
Local Hamiltonians for one-dimensional critical models
Dillip K. Nandy, N. S. Srivatsa, Anne E. B. Nielsen
Conformal field theory has turned out to be a powerful tool to derive interesting lattice models with analytical ground states. Here, we investigate a class of critical, one-dimens…
An efficient all-optical switch using a lambda atom in a cavity QED system
Anne E. B. Nielsen, Joseph Kerckhoff
We propose an all-optical switch constructed from a two-mode optical resonator containing a strongly coupled, three-state system. The coupling allows a weak, continuous wave laser…
Topological matter with collective encoding and Rydberg blockade
Anne E. B. Nielsen, Klaus Mølmer
We propose to use a permutation symmetric sample of multi-level atoms to simulate the properties of topologically ordered states. The Rydberg blockade interaction is used to prepar…
Quantum state engineering, purification, and number resolved photon detection with high finesse optical cavities
Anne E. B. Nielsen, Christine A. Muschik, Geza Giedke +1
We propose and analyze a multi-functional setup consisting of high finesse optical cavities, beam splitters, and phase shifters. The basic scheme projects arbitrary photonic two-mo…
