MERA as a holographic strange correlator
Nathan A. McMahon, Sukhbinder Singh, Gavin K. Brennen
The multi-scale entanglement renormalization ansatz (MERA) is a tensor network that can efficiently parameterize critical ground states on a 1D lattice, and also suggestively imple…
Entanglement renormalization and symmetry fractionalization
Sukhbinder Singh, Nathan McMahon, Gavin Brennen
It is well known that the matrix product state (MPS) description of a gapped ground state with a global on-site symmetry can exhibit "symmetry fractionalization". Namely, even thou…
Calderbank-Steane-Shor Holographic Quantum Error Correcting Codes
Robert J. Harris, Nathan A. McMahon, Gavin K. Brennen +1
We expand the class of holographic quantum error correcting codes by developing the notion of block perfect tensors, a wider class that includes previously defined perfect tensors.…
