How to build a teleportation machine: Teleportation protocol
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 [...]
Quantum Matter Animated!
[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 [...]
K-12 Programs
K-12 Programs IQIM interacts broadly with K-12 students and we also include teachers. Over 1,000 students participate in programs held on the Caltech campus including Project Scientist Academy, Southern California State Science Olympiad, and InnoWorks Academy. IQIM hosts high school teachers for a Summer Research Institute; a six-week immersion in the laboratory experience working directly with [...]
Steampunk quantum
A dark-haired man leans over a marble balustrade. In the ballroom below, his assistants tinker with animatronic elephants that trumpet and with potions for improving black-and-white photographs. The man is an inventor near the turn of the 20th century. Cape swirling about him, he watches technology wed fantasy. Welcome to the steampunk genre. A stew [...]
Monopoles passing through Flatland!
Like many mathematically inclined teenagers, I was charmed when I first read the book Flatland by Edwin Abbott Abbott.* It’s a story about a Sphere who visits a two-dimensional world and tries to awaken its inhabitants to the existence of a third dimension. As perceived by Flatlanders, the Sphere is a circle which appears as [...]
On the importance of choosing a convenient basis
The benefits of Caltech's proximity to Hollywood don't usually trickle down to measly grad students like myself, except in the rare occasions when we befriend the industry's technical contingent. One of my friends is a computer animator for Disney, which means that she designs algorithms enabling luxuriously flowing hair or trees with realistic lighting or [...]
The Most Awesome Animation About Quantum Computers You Will Ever See
[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 [...]

This Video Of Scientists Splitting An Electron Will Shock You
[youtube=http://www.youtube.com/watch?v=hKFecm9NKbM?vq=hd720&rel=0&showinfo=0] by Jorge Cham. Ok, this is where things get weird. 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 [...]
