Tensors are kind of like the wild west of applied math these days. They are a brave new territory and somewhat dangerous with regards to procedures one might borrow from matrices. In particular, “Most tensor problems are NP-Hard”. Despite this pessimistic result however, people are starting to utilize the additional structure available in tensor decompositions …

A new paper on the VQE
Quantum computers are a big interest of mine, and in particular I think there’s a lot to be learned in using prototype devices available in the lab today. Unfortunately, a lot of the algorithms we talk about today are simply too complex to fit on even near-future quantum devices. However, by thinking about quantum computers …
Distance is weird in many-particle quantum mechanics
Distance measures between quantum states are interesting for all kinds of reasons. I’ve been thinking about them a lot lately as they pertain to machine learning in and around quantum mechanics, as well as just generic approaches to studying many-body quantum systems. One thing that has stuck with me lately is a peculiarity of distance …
