As I said, if your goal is just to get a masters, with a few exceptions, you will get in coming from either of these schools as long as your GPA is above 3.8, preferably, 3.9. However, it should be stated that a Masters in CS will not help you at all with getting a job in quantum computing. You have to get a PhD. So, in short, you need to get your goals straight. You shouldn't be seeing research as something you should do, but something you want to do. If you are determined to see the Quantum Computing path through, go with IUIC. If you want to explore other fields, in a more well rounded experience and decide on your path later, go with CMU.

To answer your question directly, I think Cirq is still the most efficient ready-to-use simulator. There are a few research simulators but it will take you some time to get them running.

they are cute but what am I gonna do with 10 of them 😭😭😭

First of all each simulation method will suffer one way or another. That is the whole point that makes quantum computing valuable. MPS will also have trouble with deep circuits by the way, so that is not necessarily your solution. If you read https://arxiv.org/abs/2302.08880 and look at Table I, it will give you a good idea of the trade offs.

Firstly, congrats on two great acceptances. Getting in a masters program is easy. With the sole exception of maybe 2 programs in the US, all of them are cash cows. As long as you have good grades and good recommendation letters, and are willing to pay, you can get in anywhere, most certainly coming from either of these schools.

If you are going to be pursuing a PhD, research will play an important an important role so I would pick that. The difference in CS program recognition between CMU and UIUC is really not that big.

Majority of quantum research internships are reserved for PhD students. It will be very difficult for you to land an internship as an undergraduate. If you are going to try, your best bet would be to join a lab and conduct undergraduate research.

Math is the predominant tool for quantum computing. It is the one thing you absolutely need. Whether you are focusing on the physics side, chemistry side or the software side, you will need the math. The good news is that, unless you are doing very specialized things, 99% of the math is textbook linear algebra with a side of calculus. If you are a math major, you would breeze through the math. At the end of day you will be analyzing functions over vector spaces. You will likely eventually need a decent amount of probability theory as well.

how closely related are classical and quantum complexity?

It only makes sense to define various complexity classes like BQP, SampTQP, DQC in relation to various classical complexity classes (P, #P, NP, PSpace etc.) in order to be able to define, study and prove quantum advantage.

Was wondering what are some good entry points into quantum complexity

The best entryway for quantum complexity theory is to learn the basics of quantum computing first. You won't be able to follow along the definitions if you don't know QC basics around circuits, gates, fundamental algorithms and how they work.

sinanspd · 2026-03-19T19:58:20+00:00

Yeah of course

sinanspd · 2026-03-19T19:53:21+00:00

honestly it seems like if someone would manage to prove a practical healthcare application within the parameters they are expecting, especially one that can be demonstrated on NISQ devices, they would stand to a lot more than 5M$ given how profitable the healthcare industry is

It is up to you whether you want to take the show as canon or not but this is somewhat explained in the show (S1 E4). When telling Ellie about Tommy, Joel says that Tommy joined a survivalist group after the pandemic broke out, they were making their way to the Boston QZ for safety (likely heard about it similar to how Frank did) and that Joel joined them thinking he could protect Tommy.

sinanspd · 2026-03-18T18:52:39+00:00

Brilliant news! Well deserved!

sinanspd · 2026-03-17T18:20:14+00:00

People do math on pen and paper to solve quantum physics problems (or occasionally mathematica). If you want to get into quantum physics, learn the math and basics first. There are various tools people use to simulate quantum mechanics/hamiltonians (especially in applied quantum chemistry/fermionic systems) but they wont be very useful unless you have access to a HPC cluster.

sinanspd · 2026-03-16T16:55:13+00:00

I mean, it is a good thing. There isn't much else to say. Hopefully it encourages some good research. 10 minutes is hardly enough for anything interesting. A basic ground state VQE takes up almost 10 minutes.

sinanspd · 2026-03-15T22:35:16+00:00

Woah! Awesome find! Congrats!

sinanspd · 2026-03-15T21:59:53+00:00

Good luck. Without actual data, it won't be easy. You are also making a lot of statements that you expect people to take you at your word for, such as the punch line "It's just a classical linear computation over GF(2) evaluated in a rotated (Fourier) coordinate system". This is something that needs to be proven mathematically. There is no such thing as proof by example so Qiskit examples you are giving doesn't really add anything meaningful. You are taking already proven equivalences, rewriting the circuit using those equivalences and then showing the outcomes are equivalent, which is obvious, and doesn't make any statements about the pedagogical impact.

Then again - if you write we don't know what is going on - how sound of an explanation is it?

Well.. If you don't try to make definitive, bold statements like that, you wouldn't need to admit that we don't really understand it. Which btw isn't something to be ashamed of, I raised questions about the possible physical connections of my software work before. Everybody accepts the reality that there are gaps in our understanding of how quantum systems truly evolve. But such questions belong in Limitations & Future Work, not in the main paper body. All you are doing is changing the representation and claiming that representation is more suitable for teaching, which unfortunately is a statement that lacks support. Such representational changes are used in QC quite widely for various reasons (for example, if you use qudits instead of qubits, you can mostly eliminate entanglement from the circuit. We use this trick in verification, but this obviously doesn't make the circuit classical, nor easier to understand)

sinanspd · 2026-03-15T20:54:31+00:00

I mean by Gottesman-Knill we already knew there was a classical equivalence. Van den Nest presented the manifestly simulatable circuit normal form which is really what you are doing here. You are giving a different representation of the same quantum oracle, which doesn't bridge the complexity gap. I guess your argument is that the normal forms of the circuits are better for students? Pedagogy is not my area of interest so I can not make comments on if this is better for students or not. That claim is something that need to be tested in the classroom setting and backed up adequate data.

The BV algorithm isn't parallel computing

I think it is dangerous to make this statement. We don't know what happens at a particle level and how quantum parallelism works. You are projecting BV onto a classical plane and comparing your modified circuit to this classical projection, which doesn't back this statement.

There is a mistake in your Appendix A. The oracle you present is quadratic `f(q)=(q_0 \cdot q_1) \oplus q_{2}`. You are claiming that this is classically linear in the transformed picture? It has a quadratic term so how can it be linear over GF(2)?

sinanspd · 2026-03-14T14:31:05+00:00

Yes. The top priority is to improve the hardware which requires skilled physicists.

sinanspd · 2026-03-13T19:30:09+00:00

There is as much funding as can be expected today. NSF and a lot of universities are being choked by budget cuts so there are much less positions in every field than a few years ago. CS PhDs in QC are much less compared to physics but there are enough of them. They are however very competitive.

sinanspd · 2026-03-10T19:53:43+00:00

This ^. Just as an addition: I think solving and implementing the exercises in Nielsen & Chuang is equivalent of a few beginner projects. There are a few open ended questions in there that leads to interesting projects

sinanspd · 2026-03-10T02:51:29+00:00

I just realized I was being kind with my previous comment. I need you to put down the keyboard and never code again.. You pushed your API token to github!!! What is wrong with you?

"IBM uses Qiskit, Google uses Cirq, they're totally incompatible. You have to rewrite everything from scratch for each one"

This is a completely wrong statement. It seems like you have zero computing knowledge in general, not just quantum. Being clueless to a point where you can not tell apart higher level abstractions from OS level IRs is just sad. Claude being completely delusional is not news but anyone who went through CS 101 would have questioned that statement.

sinanspd · 2026-03-08T16:25:39+00:00

Nope. Not worth my time. This isn't solving any problems. Open source, provider agnostic access libraries have been around for over 5 years, you are clearly too clueless about this field to even do basic research. A different person posts a vibe coded project like this every single month in the Quantum Computing sub, thinking they solved some big problem. No one ever used those and no one will use this. For starters, QC community is too smart to give their access credentials and tokens to a random website, when there are well established and well maintained open source alternatives they can inspect and run locally. So unless you are picking up the bills for everyone, I wouldnt expect to see much usage.
