that's awesome! :)
Putting my thoughts together. Why networks beat "hero" sensors and what birds can teach us.

Watch Oskar Painter's presentation from Quantum Korea in Seoul. As Director of Quantum Hardware at AWS Center for Quantum Computing, he discusses the 'quantum tyranny of numbers' & forecasts major quantum error correction advances

A major milestone in my career, as one of the self-appointed knights of quantum.
Since I donβt think itβs possible to be this obtuse, Iβm assuming this is just marketing for your widget.
Iβm sorry I wasted my time thinking you actually wanted a definition for a quantum computer.
Iβm also sorry you need to waste peopleβs time to sell the thing but cβest la vie.
A quantum computer is a physical machine that can execute quantum algorithms with at most polynomial resource scaling.
Itβs not a βlegal termβ where I live, and my statement was clearly a conditional, so not an accusation.
Letβs stick to subjects we both understand: Are your students walking away with the clear understanding that a classical simulator with exponential scaling is not a quantum computer?
Chris, you're doing educational malpractice if your students are walking away without a clear understanding of the difference between a classical simulation and an actual quantum computer. Ignoring the entire premise of quantum computing just to sell widgets isn't a noble antiestablishment position.
Yes this is the right definition because the whole point of trying to build a quantum computer is their ability to do certain computations much more efficiently. Itβs been central since 1982.
But the most important thing IMO is centering it on scalability like Craig did.
what's wrong with this definition: A quantum computer is a physical machine that can execute quantum algorithms with at most polynomial resource scaling.
Your critique of DV didn't make much sense to me:
2- it's architecture agnostic, we can at least simulate qubits, initialization, gates, etc. in any arch.
3- who cares?
4- They're criteria, not an object description. Just like "the criteria for a valid airplane" doesn't refer to a single 747.
Personally I would go with a simpler definition: A quantum computer is a physical machine that can execute quantum algorithms with at most polynomial resource scaling.
DV criteria are necessary. Craig was just pointing out where your system clearly fails.
Raymond Laflamme 1960-2025. A great scientist, renowned for his pioneering contributions to quantum error correction. A great leader, founding director of the Institute for Quantum Computing. A great colleague and teacher whose legacy continues to inspire us.

Craig did give a definition (scalability being key), and it seems much more informative and operationally useful than your definition.
Are you having trouble understanding this definition? Maybe you can point out what is unclear about it and the community can help you.
He's right. "Nothing short of devastating"

Michael Roukes presenting slide describing a converation between him, Andrew Cleland, and Tom Kenny.
Michael Roukes kicking off #FNS2025, going back 30 years to the beginning of NEMs. (explaining this paper arxiv.org/abs/2505.04574 which was then rejected by APL!)
The building committee gets a first look at the basement of the Ginsburg Center for Quantum Precision Measurement at Caltech. We're standing where a tunnel will connect Ginsburg labs to labs in neighboring Downs Laboratory. With me are Nick Hutzler, Rana Adhikari, Michelle Effros, and Dave Hsieh.
New paper out! We resonantly couple a superconducting heavy-fluxonium qubit βοΈ to a macroscopic membrane π₯ oscillating at a few MHz. ~300 repeated interactions let us track its quantum motion, observe back-action & probe non-commuting operators. DiΓ³siβPenrose next? (1/8)

At the beautiful Les Houches for a workshop on TFLN #photonics π‘
Here are my lecture notes:

Big: The final version of a randomized, controlled World Bank study finds using a GPT-4 tutor with teacher guidance in a six week afterschool program in Nigeria had "more than twice the effect of some of the most effective interventions in education" ("equating to 1.5 to 2 years" of standard school)
Morning prayer for the faithful
Sunset!
Marko is a pioneer and leader in the field, and this is a technology existential for data centers and quantum, and all sorts of sensors and devices for health, defense ..
In fact Iβm flying to a summer school theyβre holding in France right now to give a lectures on this research. Crazy to cut it.
I guess Iβm trying to separate two concerns. Trying to understand if the ickyness is over a human not being paid or studio ghibli not being paid.
