About Whirl

I think about next generation quantum technologies, among other things.

    First I heard of these exascale computers was when a Chinese group published[1] a pre-print in which they classically replicated the Google quantum supremacy result in about 300s. …

    If you want to import anything at all you need foreign currency. One of the ways you can do this is by exporting goods, of course, but you could also sell some of your local curren…

    I’m of a similar opinion, but with the note that QCTRL actually makes products that people want. The current state of the art in QC requires that pretty much everyone needs some ki…

    I use blogdown, which handles a lot of dumb bullshit that comes with static site generation. Also supports latex, markdown and you can use RStudio to create and preview posts. http…

    The apparatus you’re thinking of is called a dilution refrigerator. The “tiny pipes” are actually coaxial signal cables carrying RF and DC control signals. These terminate at a “pa…

    This is true for now. The IARPA SuperCables program exists to tackle this specific problem. Probably the solution will require converting microwave pulses into optical frequencies …

    They’re clearly pretty serious about it (why build a gigantic dilution refrigerator, otherwise?) but they’re definitely going to need to wring a factor of two out of the precision …

    Have you considered industry research positions? Depending what field, there could be high demand for your skill set, even if the research is not exactly what you did in your acade…

    Oh and don’t forget that whatever it is you do should be valuable to other people

    There are annealers that have thousands of qubits (DWave), but they are low coherence and very different from the gate model qubits in use by Rigetti, Google, IBM, which are themse…

    They could using a small EMP weapon. These happen to have short range and are explosively pumped, so at that point it’s easier to just disrupt the magnetometer by initiating rapid …

    My understanding is that it doesn’t have to absorb energy to perform calculations. The reversibility dependent on keeping track of all of the correlations in the system. Michael Fr…

    I didn’t really appreciate the difficulty of modern semi-conductor fab until I read this.

    I’d echo what the others have said re: pay and flexibility and add another point- Autonomy and Impact- people need to feel like they own their work and that it matters to someone. …

    This is accurate. As far as I can tell, this work is akin to discovering the Josephson effect for superconducting qubits. Still a lot of work to be done to figure out how to braid …

    Agree with this. I felt the same about writing, but eventually found that having strong feelings about my chosen topic helps a lot. I’ve never been able to write for the sake of wr…

    Have you tried the Maruman ‘Mnemosyne’ notebooks? They have (thin) hard plastic covers, but I’m not sure if you’d count that as a hardcover. I really like my TWSBI Diamond 580 with…
