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. The Google team estimated that a supercomputer (Summit) woul

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 currency in exchange for dollars or whatever. Bitcoin volatility m

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 kind of pulse shaping/noise reduction, which is (some of?

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. https://github.com/rstudio/blogdown

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 “package” which contains the chip on which the superconducting

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 to get the signals out of the cold spaces with fiber-optic i

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 of their device fabrication process. Specifically, the laser

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 academic life. I went to industry immediately after grad school a

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 themselves lower coherence than the ions being used by IonQ and Ho

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 explosive disassembly.

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 Frank has a decent lecture on the subject: https://

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. Meaningful (subjectively defined) work is an important motiv

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 anyons or build better anyons, etc. TBH I didn’t even expect

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 writing, so I only author posts when I feel strongly about the

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 Noodler’s Walnut, but it looks best on yellow paper. I trie

This is becoming less true. The field is still very PhD heavy, but some employers definitely hire people right out of an undergraduate Physics or ECE degree. They end up effectively completing a PhD program on the job, but don’t get the fan

I once spent an internship running a fluorescent dye laser operated by an computer running DOS (maybe MS DOS?). It was terrifying, but the beast worked perfectly well. And my PhD lab was using mass-spectrometers that still required vacuum t

I’m pretty sure the way people in my field (physics) do this is by reading deeply enough that they A) recognize the names of authors that do good work B) Develop intuition about which results are probably BS and which results are likely to

Probably because a quantum computer that can actually factor a large enough prime is between 10-30 years away. The technical challenges are... substantial. The article mentions NIST’s effort toward a post-quantum encryption standard. Hopefu
