I’ve always been a proponent of the idea that one of the best ways to learn about a topic is to code up a simple example that uses that idea/concept/algorithm. In conversations I’ve had with students recently, I’ve realized there…

It’s been some time since our original hybrid quantum-classical algorithm, the variational quantum eigensolver (VQE), made its debut on a photonic quantum device. Since that time there have been many developments, some of which I outlined in a previous post…

As an extension to my last post on rendering Processing code in an IPython notebook, I thought it might be fun to play a bit with the 3D functionality and see how easy it would be to build an extremely…

Quantifying the volumes of different types of quantum states with respect to each other is an interesting tool for analysis that I’ve recently become interested in. For example, did you know the volume of separable states is super-doubly-exponentially small with…

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…

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…

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…
