Not at all clear from the paper whether you need a quantum computer to do these calculations or whether the same circuits could be simulated classically. (I.e. from what I can see the paper never mentions the amount of entanglement or compl

I encourage people to read the article for themselves and reach their own conclusions.

To clarify a bit more, for us the purpose of opening the oracle and simulating it, whether or not we were the first ones to do it (e.g. we weren't, see Chamon paper above) was to say that "There are many cases where it's alre

Your comment is helpful to us to see what are some common misunderstandings about what we are saying in our paper versus not saying. It could be some problems with our writing. For example, we state all of the things you said above explicit

As one of the authors, I'm ok with reasonable disagreements (e.g. see D. Bacon's below) about whether our overall conclusions are justified. But I feel it important to point out that your comment above is just a pure misrepresenta

I have a dumb question that keeps nagging me, and wonder if someone here has a good answer. What does Web3 necessarily have to do with the web? Couldn't an iOS app which uses blockchain technology as a decentralized database be just as

My favorite is the quantum computing researcher Toby Cubitt.

An easy to read (minimal theorems) but authoritative and modern introduction to tensors can be found in the book “An Introduction to Tensors and Group Theory for Physicists” by Jevanjee ( https://www.springer.com/gp/book

Last paragraph of the article for some reason: “The CDC also said the report is “insufficient” to draw conclusions about the effectiveness of the authorized vaccines against Covid, including the delta variant, during this outbreak.”

Often one is not really interested in solving Ax=b for all possible b but just one particular b. In that case one can iteratively solve for x by algorithms like conjugate gradient which only require multiplying A times the current best gues

To your first question, probably not any time soon. The main quantum algorithm for breaking (certain types of) cryptography is Shor’s algorithm, and will probably need error-corrected quantum computers with at least hundreds of logical qubi

Conformally symmetric critical systems are often, though not always, studied by modeling them by conformal field theories, which do involve an action obeying a conformal symmetry. A good reference about conformal field theories is any book

Seems notable that they are using the Sinopharm and Covishield vaccines which have been found to be less effective than vaccines like Pfizer or Moderna. Also that 63% of people with new cases had either not been vaccinated or had received o

It really blows my mind to think of the things experimental physicists have accomplished and continue to accomplish. One example is molecular beam expitaxy (MBE) technology that lets researchers deposit layers of a material that are literal

I think for most people defund sounds like “take away all funding for” which would be tantamount to abolishing.

Another important consideration is library development. As someone developing a large library, when we were previously developing in C++ we would encounter large barriers where some design goal we had either couldn't be done in the lan

What about students from countries whose time zone is 12 hours different? They can watch lecture recordings, sure, but miss out on asking live questions or participating in discussion groups with other students unless they stay up through t

Agree, though for many Americans it doesn’t take too much energy since they don’t pay any attention to what’s going on in other countries.

Here's a brief statement by Anderson that he wrote for the website www.edge.org. Apparently his main issue was that string theory isn't experimentally driven: """ Philip W. Anderson Physicist and Nobel laureate, Pri

One thing I didn't see mentioned about creating software is that the tools and the systems often have serious problems to begin with, even before you start writing a program. Some well known examples are: - major programming languages

Agreed. There is still a lot of work left to do!

There is a lot of evidence for what Paul says once you dig into a specific field. Taking two fields I know well: in physics, there was decades of work on fundamental questions on systems in equilibrium, while many obviously important open q

I agree it's an important question. But one thing often left out of the possible answers is to go forward with using cheap labor overseas while also providing a very strong safety net and job retraining options to those who lose their

Regarding Lukin’s experiment - which is very interesting and high quality - in most instances it can be simulated by existing classical methods (matrix product states / DMRG being a key example). This does not detract from the importan

I agree they do, but in my experience they also make them do aptitude tests like whiteboard coding or asking trick math questions. These tests overlook the actual (rare) skills the candidate has in favor of skills more often known only to c

Too many religious people that I know think that scientists have it out for them and/or are conspiring against them. Enough articles like this and it will prove their point for them (the statement equating being irreligious with acting
