Quantum Optics

The second one of the TED-Ed lessons I wrote about quantum physics has now been published: What Is the Heisenberg Uncertainty Principle. This is, again, very similar to stuff I’ve written before, specifically this old blog post and the relevant chapter of How to Teach [Quantum] Physics to Your Dog. As usual, I tried but…

My TED@NYC adventure last fall didn’t turn into an invite to the big TED meeting, but it did lead to a cool opportunity that is another of the very cool developments I’ve been teasing for a while now: I’ve written some scripts for lessons to be posted with TED-Ed. The first of these, on particle-wave…

I didn’t write a summary of the third day of “Quantum Boot Camp” to go with my Day One and Day Two summaries for a simple reason: I would’ve needed to do that on Saturday, and I spent Saturday in transit back to the US. More than that, though, it was harder to summarize than…

The second day of the “Quantum Boot Camp” was much lighter on talks. The only speaker was Ray Laflamme from the Institute for Quantum Computing in Waterloo, who gave a nice introduction to quantum technologies. While he did spend a bit of time at the start going through Shor’s algorithm for factoring numbers (following up…

Since this part of the trip is actually work-like, I might as well dust off the blog and post some actual physics content. Not coincidentally, this also provides a way to put off fretting about my talk tomorrow… I’m at the Nordita Workshop for Science Writers on quantum theory, which a couple of the attending…

A couple of weeks ago, io9 ran a piece about the old accusations that Robert Millikan manipulated his data for the electron charge with the headlineDid a Case of Scientific Misconduct Win the Nobel Prize for Physics? that got a lot of attention. I wasn’t as impressed with this as a lot of other people,…

Small College, Exotic Particles

Topping the looooong list of things I would give a full ResearchBlogging write-up if I had time is this new paper on a ultra-cold atom realization of “Dirac Monopoles”. This is really cool stuff, but there are a lot of intricacies that I don’t fully understand, so writing it up isn’t a simple matter. The…

I’m teaching Quantum Optics this term, and one of my students picked “Atom Optics” off the list of suggested paper topics. When he asked for pointers, I said “You should check out the diffraction stuff Markus Arndt’s group does.” And just like that, a paper from the Arndt group turns up from the Arxiv Blog……

Two papers with a similar theme crossed my social media feeds in the last couple of days. You might think this is just a weird coincidence, but I’m choosing to take it as a sign to write about them for the blog. So, what are these papers, and what’s the theme? One is the final…

Quantum Erasure

When I posted congratulating the winner of this year’s Nobel betting pool, I received a gentle reminder in email that I’m a Bad Person and still haven’t done one of the posts I owe to the 2011 winners. Evan reminded me that he asked for something about the delayed-choice quantum eraser, so let’s talk about…
