In the first post of this series, I described some frustrations I had with what we were told to do in TA training. In the previous post, I recalled some memories of interactions I had with John Preskill while I was working at the IQI. When it came time for me to give my last [...]
[youtube=http://www.youtube.com/watch?v=T2DXrs0OpHU?vq=hd720&rel=0&showinfo=0] by Jorge Cham You might think the title is a little exaggerated, but if there's one thing I've learned from Theoretical Physicists so far, it's to be bold with my conjectures about reality. Welcome to the second installment of our series of animations about Quantum Information! After an auspicious start describing doing the impossible, this [...]
Faculty, Quantum Information

If quantum computers, femtometer motions or laser alligators weren't enough, let's throw in fractionalized electrons, topological surfaces and strings that go to the end of time. To be honest, the idea that an electron can't be split hadn't even occurred to me before my conversation with Gil [...]

I often get suggestions for comics I should draw, which I welcome because A) I like to think of PHD Comics as a global collaborative effort and B) after 17 years, I'm almost out of ideas. This particular suggestion came from Chen-Lung [...]
[youtube=http://www.youtube.com/watch?v=pktWhH6m_DM?vq=hd720&rel=0&showinfo=0] by Jorge Cham What does it mean for something to be Quantum? I have to confess, I don't know. My Ph.D was in Robotics and Kinematics, so my neurons are deeply trained to think in terms of classical dynamics. I asked my siblings (two engineers and one architect) what comes to mind for them [...]
Damn, it sure takes a long time for light to travel to the Pegasus galaxy. If only quantum teleportation enabled FTL Stargates… I was hoping to post this earlier, but a heavy dose of writer’s block set in (I met a girl, and no, this blog didn’t help — but [...]
First slide, viewed on my laptop. I'm lazy. The only reason I ever do anything is that sometimes in a weak moment I agree to do something, and after that I don't have the nerve to back out. And that's how I happened to give the introductory lectures leading off the 12th Canadian [...]
A Sun 3/60 Workstation in the late 1980s. I recently did an interview for an educational video about quantum physics. The filmmaker, who needed some cutaway shots to stitch the interview segments together, suggested a shot of me walking through the server room in my building. I complied, gazing with [...]
The following post is a collaboration between visiting undergraduates Evan Giarta from Stanford University and Joy Hui from Harvard University. As mentors for the 2013 Caltech InnoWorks Academy, Evan and Joy agreed to share their experience with the audience of this blog. All throughout modern history, science and mathematics have been the foundation for engineering [...]
