I think you will have best luck by searching for "open quantum systems" toolboxes in your language of choice. My preferences are, in order: - QuantumOptics.jl in Julia - QuantumToolbox.jl in Julia - qutip in python These are all &

The description she gives of what she is doing is a stellar example of good scientific inquiry. The problem, or at least my perception of the situation, is that she does not do what she claims to be doing. She forms uninformed opinions opti

While I sympathize with some of your arguments, you are wrong about scholarships. Getting financial aid as a foreign student at an institution like Harvard, Yale, or MIT is the norm.

Independently of political opinion, I believe your edit and anger at downvotes are due to misunderstanding the etiquette of the forum. Forum moderators have repeatedly described the culture here as "downvote without a comment is a perf

I have the same infuriating issue. Still using thunderbird because of principles, etc, etc. But this does seem to be a different issue from the one OP mentioned. Seems to be actually this one: https://connect.mozilla.org/t5&

Quantum Information Science classes now exist at most universities. If you have average linear algebra and probability theory knowledge, it is relatively easy to jump into them (without physics background). The Scott Aaronson lecture notes

ugh... Needing more than 4 significant digits is a pretty baseline requirement for precision physics experiments meant to falsify various candidate theories. 2 new significant digits is a vast parameter space that now can be excluded. Needi

You should have started, not ended, your post with "Anna's Archive" ;D I did not know of it, which is why I used scihub.

She said "because the color centers are small which would enable miniaturization". Miniaturization is the last thing these are good for, and while they are "small" for a human, they are gigantic for an electronic device.

On the contrary, we have plenty of examples of long-lived (many hours, days, or more) examples of superposition in many solid state materials and chemical systems. For a quantum computer you need both (1) something that can retain superposi

There has been a programmable electromechanical computer build in the late 1800? Not just a simple calculator? Please share examples, this sounds awesome. Yes, late 1980s is when I would say quantum computing was conceived. I gave plenty of

You are right about that (well, except all the progress in classical complexity theory and algorithms, cosmology, condensed matter physics, material science, and sensing, which stemmed from this domain). But, for the little it is worth, it

I do not think this is the right metaphor. Having 5 devices work out of 21 is actually a better yield than what TSMC would get with a brand new process. This is not just normal, this is expected. It is all the other allegations that make th

Extreme specifics: her comments on work out of MIT on Color Center Qubits was basically "finally an example of actual progress in quantum computing because of reason A, B, C". That statement was in the class of "not even wron

But there is no scalable computational advantage with quantum annealers. They are not what most people in the field would call a "(scalable/digital) quantum computer".

And every time you use a transistor, observe a green plant living, or see that your hand does not pass through the table when you tap it, you see quantum mechanical effects working at scale. Every time you use a telescope, you see quantum i

This is such a beautiful theoretical idea (a type of "natural" error correction which protects the qubits without having to deal with the exorbitant overhead of error correcting codes). It is very disheartening and discouraging an

I am amazed people consider 1440p low resolution. My knee-jerk reaction was to assume you were sarcastic. I use a monitor of roughly that many lines of pixels and have never had observed blurry text in the tools I use (and I use fairly smal

It is really saddening for me to see how much N800/N900 and the Maemo platform are mentioned here, as an example of Nokia actually being first to introduce many of these technologies, but then Nokia dropped them a few years later. I st

Isn't "preferential caching" just Netflix providing a caching server for free to the ISP? Is this that different from Netflix building more CDN servers worldwide? It is Netflix paying in either case without exploiting their m

That is true -- all we can show is sustained exponential improvement in figures of merit like qubit lifetime and coherence, scalability, gate fidelity over the span of 25 years. As long as this exponential pace of improvement does not stop

From someone actually working on developing this type of hardware: no, there is no entity in the world that is anywhere close to building a device that can run Shor's algorithm. We will have standardised post-quantum algorithms long be
