This post is about generating a special type of light, squeezed light, using a mechanical resonator. But perhaps more importantly, it’s about an experiment (Caltech press release can be found here) that is very close to my heart: an experiment that brings to an end my career as a graduate student at Caltech and the [...]
It is Monday afternoon and the day seems to be a productive one, if not yet quite memorable. As I revise some notes on my desk, Beni Yoshida walks into my office to remind me that the high-energy physics seminar is about to start. I hesitate, somewhat apprehensive of the near-certain frustration of being lost [...]
Physicists are not known for finesse. “Even if it cost us our funding,” I’ve heard a physicist declare, “we’d tell you what we think.” Little wonder I irked the porter who directed me toward central Cambridge. The University of Cambridge consists of colleges as the US consists of states. Each college has a porter’s lodge, [...]
We hope you’ll join us for a public lecture presented by Nicole Yunger Halpern featuring her recent book Quantum Steampunk, the Physics of Yesterday’s Tomorrow. Nicole completed her PhD in 2018, working with John Preskill and has been an active member of the IQIM community. We’re excited to share her new book with you. Friday, [...]

Welcome to the second installment of our series of animations about Quantum Information! After an auspicious start describing doing the impossible, this [...]

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 [...]
Burning Man... what a controversial topic these days. The annual festival received quite a bit of media attention this year, with a particular emphasis on how the 'tech elite' do burning man. Now that we are no longer in the early September Black Rock City news deluge I wanted to forever out myself as a raging hippie and [...]
