The Friday gathering also offers a chance to interact with other research groups in informal discussions. If you are interesed in presenting, please [...]
How to build a teleportation machine: Intro to entanglement
Oh my, I ate the whole thing again. Are physicists eligible for Ben and Jerry’s sponsorships? I’m not sure what covers more ground when I go for a long run — my physical body or my metaphorical mind? Chew on that one, zen scholar! Anyways, I basically wrote the following post during [...]
What’s inside a black hole?
I have a multiple choice question for you. What's inside a black hole? (A) An unlimited amount of stuff. (B) Nothing at all. (C) A huge but finite amount of stuff, which is also outside the black hole. (D) None of the above. The first three answers all seem absurd, boosting the credibility of (D). [...]
Talking quantum mechanics with second graders
“What’s the hardest problem you’ve ever solved?” Kids focus right in. Driven by a ruthless curiosity, they ask questions from which adults often shy away. Which is great, if you think you know the answer to everything a 7 year-old can possibly ask you... Two Wednesdays ago, I was invited to participate in three Q&A [...]
A detective with a quantum helper
Have you ever wanted to be incredibly perceptive and make far-reaching deductions about people? I have always been fascinated by spy stories, and how the main character in them notices tiny details of his surroundings to navigate life-or-death situations. This skill seems out of reach for us normal people; you have to be "a high-functioning [...]
Quantum gravity from quantum error-correcting codes?
The lessons we learned from the Ryu-Takayanagi formula, the firewall paradox and the ER=EPR conjecture have convinced us that quantum information theory can become a powerful tool to sharpen our understanding of various problems in high-energy physics. But, many of the concepts utilized so far rely on entanglement entropy and its generalizations, quantities developed by [...]
Opportunities
Opportunities Membership in IQIM is through affiliation with an IQIM faculty member or research group participating in IQIM. IQIM is not a separate department; all members of IQIM are also members of the Physics, Applied Physics, Computer Science, or other associated department. The path to join IQIM is first to join the institute in [...]
