Reading the competition rules, the prize will be awarded for algorithms that do the most societal good with the smallest estimated size of quantum computer - There is no requiremen…

I agree with parent (despite the downvotes), there's an ontological mismatch in the title. Mathematical constructs by themselves cannot reveal truths about the physical world. Inst…

No quantum computing platform today has meaningful error correction. What you can get, in some cases, is limited error detection based on the outcome of the question computation, i…

What would be the example of an outstanding, reasonably-sized (even quantum computers of the future have finite resources) quantum simulation problem that is intractable today but …

You can create a free account at IBM Quantum and peek at the latest calibration data there. Edit: Only a fraction of the qubits of the 127 qubit system were calibrated when I looke…

There's a commercial product for classical simulation of small QPUs [0]. With dedicated hardware handles up to 41 qubits. I'm not affiliated with the company or endorsing their pro…

For anyone struggling to make sense of this: I have a physics PhD, I have spent most of my career in fundamental research, I have read the Wikipedia article and other references mu…

This is quite a convoluted way of making an electrical switch. In brief, the carriers of supercurrent (Cooper pairs) in the channel are "depleted" (actually: broken up) by a local …

I appreciate your views otherwise, but I did not use or imply "fraud" in my comment(s).

Not the person you're replying to, but I admit to characterizing your paper as "garbage" in another comment thread. Since you're inviting discourse, which I greatly appreciate, I'm…

Just posting to lament the fact that there are two blatantly garbage-tier research articles on the front page at the moment (this and the Ramanujan machine).

> How is this achieved in practice? Wish I knew. I think my take-home from this discussion is that the honor code can be made to work in the right circumstances that exist, at leas…

I was aware of the implications, hence the disclaimer "(Bad if ...)" However, I'd assume that doing either during a test would be against the honor code.

My counterarguments, in good faith: Clearly, any society collectively benefits from honesty, whereas an honest act is, at least in a strict game-theoretic view, a loss to the indiv…

Interesting, thanks for the replies. I'd still point out that the system is not robust against: - Working in groups. (Bad if tests are supposed to assess individual performance.) -…

I spent a few years at Caltech in an academic role (not as a student). I never understood the rationale behind the unsupervised take-home exams. Could you elaborate what is it that…

I think your question is excellently phrased. The answer for anything data science-y is "no." The bottleneck will be transferring the input data onto the quantum CPU. For algorithm…

What seems to be missing from the replies posted so far is the notion of coherence, and the choice of measurement basis. What separates a coherent "quantum" superposition, say, |0>…

This! I used to be puzzled by how anyone could ever drive off with the nozzle still in the car. I had only seen the non-latching dispenser, and service stations don't exist in my c…

Agree with sentiments of the parent comment. I believe the prestige and social standing of physics (and, in part, the academia as a whole) is founded in the truly transformational …

What is an interesting career to pivot into for someone who's spent 10+ years in physics research? At the age of ~35, I'm about to start my fifth academic appointment at the postdo…

A contrarian view: Quantum Computing would not be near the top of my list of things to teach in high schools. The students would be better off learning about scientific ideas that …

My case: Presently in US on a cap-exempt H1B. Planning to resign from my current position in a few months' time, and (eventually) relocate to another country. Q: Can I make use of …

Continuing: Google (or anyone else) hasn't shown an implementation of an error correcting code, so we do not have data points for a model-free "ruler extrapolation" of logical erro…
