This award involved some clever engineering to set up quantum effects in a macroscopic system, but was there any new physics involved here? (Still better than last year's award which wasn't really physics at all!)

It's highly non-trivial claim that macroscopic system can have quantized energy levels and exhibit measurable quantum effects. You can't just solve Shroedinger equation of 10^24 particles to show that.

For those looking for a good pop-sci introduction to these sort of quantum effects and why demonstrating macroscopic quantum effects is a big deal for the foundations of the field I recommend “Through Two Doors at Once” by Anil Ananthaswany.

Is this inferring to the double slit experiment?

Yes

Earlier quoted context omitted.

Comments like these make me realize most people have no clue what science is really like.

I don't think so, I just think they expect that Nobel Prize level physics should feel less incremental, and everything that doesn't involve a revolution in physics (like supersymmetry) or at least an expected confirmation of an old revolution (like the Higgs boson or gravitational waves) feels incremental.

It would be pretty crazy to have enough big breakthroughs in physics to warrant a prize every year. I guess that’s how it was for a brief period in the early 1900s.

I spent time in UCSB’s physics department and Prof. Martinis was one of those experimental physicists who knew more about electronics and measurements than the typical electrical engineer. He used to have a wiki page containing documentation, cad files, etc of circuits that his group developed for his measurements and he also had open source software for controlling electronics. Very cool prize and happy to see UCSB getting one more Nobel prize!

Exactly, also in it's goal to "demonstrate quantum tunneling macroscopically" haven't we had tunneling diodes for quite a while? The device uses tunneling for its basic functionality

In those cases doesn’t the tunneling occur one electron at a time, and so not macroscopic?

Great to see the University of California, Berkeley and the University of Cambridge, UK continuing to add to their already outstanding number of Nobel laureate alumni. The Paris-Sud University was a new name to me. Apparently, this will be the 4th Nobel laureate associated with the university.

French higher education institutions work in very different ways from the standard US model; two relevant caracteristics are: a) good institutions for education and for research might not be the same at all and b) institutions work in a much more networked ways, so many labs will be joint ventures between like 5 universities/schools and 3 national research centres, students might get three degrees with each of them being a joint program between several schools.

So it's hard to have a good grasp.

More than deserved! Both Devoret and Martinis are also highly involved in pushing quantum engineering to new levels - Devoret at Google Quantum AI and Martinis (formerly at Google) with his company, Qolab. Coincidentally, I have a close friend doing his PhD with Devoret and know someone working with Martinis. I am curious to see if they will ever see their respective supervisors again, given that the Nobel Prize atte…

Invitations is one thing I think they can mostly pick on their own volition with one exception.

The prize rules stipulate that they need to hold one lecture related to their winning topic with the institution that picked the winner within 6 months.

Iirc the 2024 physics prize lecture (on the roots of neural networks) was held in the days just before the prize giving ceremony and can be watched on the Swedish broadcasters "education" channel as well as youtube.

Michel H. Devoret, Chief Scientist at Google Quantum AI, and in April 2020 John M. Martinis resigned from Google after being reassigned to an advisory role. [0] Sounds like there was some politics shenanigans between them where Martinis was moved into a useless role and took the hint at the height of covid lockdown. [0] https://en.wikipedia.org/wiki/Michel_Devoret

You linked the wrong article

He left because the reorg stripped his hardware decision authority, and he wouldn’t stay without control to drive the technical plan.[0]

He kept working on the problem. The question now looking back over 6 years is did Google make a mistake. I've seen this at IBM and other large research divisions where people who did something significant 20 or 30 years in fields like AI become stagnant burning tens and hundreds of millions. There was a political battle and Martinis got pushed out. The question I have is did the people who pushed him out know the path forward in quantum computing or did they just know how to play office politics licking the correct behinds.
