Trying to understand the ground state of the AKLT model, and having trouble parsing the paper. Here's how it's described in the famous AKLT paper, and the corresponding Hamiltonian:pic.twitter.com/wv9iEBF1k5

Fact that linear cluster state Hamiltonian has, essentially, the same physics is not an accident. It’s in same phase as AKLT
Curious if "same phase" implies "if one be used as a substrate for QC the other can too" (and vice versa)?

(I know that some AKLT states can be used as a substrate for QC. But wondering in general what statements can be made.)

For linear states like this you might hope for 1 qubit MBQC with pretty much any state “in the phase.” it is lucky that Dominic Else is cleverer than those lightweights Bartlett and Doherty https://arxiv.org/pdf/1201.4877 ! State of the art, I think: https://arxiv.org/abs/1803.00095
