Fractional quantum Hall states under density decoherence
Zijian Wang, Ruihua Fan, Tianle Wang +2
Fractional quantum Hall states are promising platforms for topological quantum computation due to their capacity to encode quantum information in topologically degenerate ground st…

Lower bounds on the complexity of preparing mixed states
Max McGinley, Samuel J. Garratt
We establish a relationship between the correlations in a many-qubit mixed state and the minimum circuit depth needed for its preparation. If the mutual information between two sub…

Quantum Algorithm to Prepare Quasi-Stationary States
Samuel J. Garratt, Soonwon Choi
Quantum dynamics can be analyzed via the structure of energy eigenstates. However, in the many-body setting, preparing eigenstates associated with finite temperatures requires time…
