Constructing topological models by symmetrization: A PEPS study
Carlos Fernandez-Gonzalez, Roger S. K. Mong, Olivier Landon-Cardinal +2
Symmetrization of topologically ordered wavefunctions is a powerful method for constructing new topological models. Here, we study wavefunctions obtained by symmetrizing quantum do…
Can long-range interactions stabilize quantum memory at nonzero temperature?
Olivier Landon-Cardinal, Beni Yoshida, David Poulin +1
A two-dimensional topologically ordered quantum memory is well protected against error if the energy gap is large compared to the temperature, but this protection does not improve…
Practical variational tomography for critical 1D systems
Jong Yeon Lee, Olivier Landon-Cardinal
We improve upon a recently introduced efficient quantum state reconstruction procedure targeted to states well-approximated by the multi-scale entanglement renormalization ansatz (…
Efficient Direct Tomography for Matrix Product States
Olivier Landon-Cardinal, Yi-Kai Liu, David Poulin
In this note, we describe a method for reconstructing matrix product states from a small number of efficiently-implementable measurements. Our method is exponentially faster than s…
