Billions of entangled particles

This has been making quite a bit of news lately, the entanglement of 10^10 spin pairs. (Image from the paper on Nature.) Here are a few different articles:

Quantum Computing Video Lectures

I'm not familiar with the author, but here's a blog post with a whole slew of quantum computing video lectures. I've seen some of them such as Deutsch's before.

Introduction to models of quantum computation and quantum programming languages

Miszczak has put together a paper, Introduction to models of quantum computation and quantum programming languages. Skimming through it, it seems to be a good overview of the subject and a quicker read than some other texts at 40 pages. While not a complete overview of quantum programming techniques, still worth flipping through. The abstract:

The goal of this report is to provide an introduction to the basic computational models used in quantum information theory. We various review models of quantum Turing machine, quantum circuits and quantum random access machine (QRAM) along with their classical counterparts. We also provide an introduction to quantum programming languages, which are developed using the QRAM model. We review the syntax of several existing quantum programming languages and discuss their features and limitations.
