Every now and then, an area of research becomes so promising and complex, that coordinating the efforts of individual researchers accelerates progress towards groundbreaking discoveries. In that light, the Division of Physics at the National Science Foundation introduced the Physics Frontiers Centers to tap into the collective intelligence and skills of, otherwise, autonomous research groups.

The Institute for Quantum Information and Matter (IQIM) at Caltech is the newest Physics Frontiers Center supported by the National Science Foundation and the Gordon and Betty Moore Foundation. Here at IQIM, we study physical systems in which the weirdness of the quantum world becomes manifest on macroscopic scales. Our work spans a wide range of cutting edge research, from superconductivity and nanotechnology, to exotic phases of matter and quantum computation!

As a Physics Frontiers Center, we are tasked with moving science forward, often against seemingly insurmountable obstacles. From the outside, the progress we make resembles sudden bursts of genius. But real science is much more than a series of Eureka! moments strung together. Through personal accounts highlighting the experimental and theoretical progress here at IQIM, we plan to take you on a behind-the-scenes tour of the fascinating research we get to do everyday…

  1. Sean Carroll posted a link to one of your posts on Google+. Great post (about qubits). I’d like to follow this blog. But it doesn’t seem to have an RSS stream. So I can’t put it into my Google Reader. The Follow link at the top seems to put it into a WordPress reader, which has nothing but this blog. Any chance of making is more generally accessible?


    • Dear Blue cat, have you tried the drop-down menu with the option to subscribe through Google? The menu is found on the page that links to our feed at the top right of our blog. Please let me know if this works for you.

      • The page that links to your feed at the top right of your blog? Which page? All the pages I see from your blog have New Post, my name, and a search box at the top right? The top left has a Follow option, but that just subscribes me to a WordPress feature. Is there some other page not on the blog but that links to the blog that I should be looking at?

  2. Besides this, could there be other benefits of teleportation, and is it possible to teleport raw materials? Could you publish an article about this?

  3. Quantum mechanics at its simplest boils down to this equation:

    DeltaE = nh

    h is a very small but still finite number.

    What would this be for classical (i.e. non-“weird”) mechanics? Wouldn’t it be the same except that h would be an infinitesimal? In this case DeltaE could never be anything other than an infinitesimal. Is this equivalent to Parmenides’ paradox wherein he brands all change as logically impossible? From my perspective this is a lot weirder than quantum mechanics.

    How would have Parmenides responded to quantized change?

  4. My name is Michael, from Montreal.

    I’m writing a book that will be placed in the “far future”.

    During my research I came across your blog, and I have to say that I enjoy it very much. I will have to get back to in in more detail later.

    Long story short, I was wondering if you would be kind enough to answer few questions? I’m unable to find the answers and hope that you might help:

    1. After a free neutrino has turned into something, can it be turned into something else after its first “decision” (and into what if its possible- if not why not), and if it is possible what would be hypothetical catalyst for that change be?

    2. How do we define a “quantum process” exactly? I’m referring to a process that turns, for example. a down quark into a up quark and a W- ? I’m aware that the term is still unclear, but hope to understand more.

    3. Since only “observance” makes a neutrino change it’s nature from all into one, how do we explain the existence of electrons etc? What, apart from our interaction is actually interacting with neutrinos? Is it therefore another catalyst, not yet discovered?

    I honestly hope that my questions didn’t bother you too much.

    Hoping for your answers,
