Learning transitions of topological surface codes
Finn Eckstein, Bo Han, Simon Trebst +1
For the surface code, topological quantum order allows one to encode logical quantum information in a robust, long-range entangled many-body quantum state. However, if an observer…
Two-dimensional coherent spectroscopy of CoNbO
Yoshito Watanabe, Simon Trebst, Ciarán Hickey
With recent advances in terahertz (THz) sources and detection, two-dimensional coherent spectroscopy (2DCS), which allows to probe nonlinear responses in a two-frequency plane, now…
Symmetry-deformed toric codes and the quantum dimer model
Jiaxin Qiao, Yoshito Watanabe, Simon Trebst
Motivated by the recent introduction of a -symmetric toric code model, we investigate symmetry-based deformations of topological order by systematically deconstructing the Ga…
Flow to Nishimori universality in weakly monitored quantum circuits with qubit loss
Malte Pütz, Romain Vasseur, Andreas W. W. Ludwig +2
In circuit-based quantum state preparation, qubit loss and coherent errors are circuit imperfections that imperil the formation of long-range entanglement beyond a certain threshol…
Learning transitions in classical Ising models and deformed toric codes
Malte Pütz, Samuel J. Garratt, Hidetoshi Nishimori +2
Conditional probability distributions describe the effect of learning an initially unknown classical state through Bayesian inference. Here we demonstrate the existence of a \texti…
Decoherence-induced self-dual criticality in topological states of matter
Qingyuan Wang, Romain Vasseur, Simon Trebst +2
Quantum measurements performed on a subsystem of a quantum many-body state can generate entanglement for its remaining constituents. The whole system including the measurement reco…
