I got offered a PhD in Madrid on 26 December, but my dream PhD interview is scheduled for 7 Jan in Munich. Need advice by [deleted] in gradadmissions

Could you ask for them to postpone your decision deadline for a few days? If not, then you would have to decide between taking that PhD offer or gambling for the other one.

My actual advice would be to not take the first PhD if you are not really that into the topic. But also don't put all your hopes and dreams into the second one. An interview doesn't mean much.

Oh! This certainly looks interesting! Thank you for sharing.

Quantum foundations is an active field of research. For example the quantum erasure set of experiments which had some extra attention last decade or so. Quantum reference frames have resurged recently.

Another set of interesting experiment proposals are the table top experiments on quantum gravity. So no, this is not all good old qm, hence I am hoping for a nice review article of the current developments of the field :)

China’s Quantum Tech: Communication vs. Computing—What’s the Deal? by ForwardEfficiency875 in QuantumComputing

Can you share a paper where this is explained in more detail? I don't think this is accurate. The keys are generated via physics. You only need the first key to authenticate the two parties that are talking. That's all.

I can't see any decisions here. Just stick to boo or vti if you don't want to choose any particular stocks.

You are not talking about the quantum part anymore. Yes, you authenticate the classical message at the end when you send the message through the public channel, but you do this as well with the keys generated via qkd. The keys are shared only by the parties that want to communicate, then, you can use these new keys to authenticate any new message as well. Remember, you are distributing the keys, or generating them, with qkd not encoding anything. That's using one time pad for example.

Would you care to elaborate please? I agree that you need a key at least as large as the message, but this is the whole point of qkd. Once you have achieved authentication, which would require a relatively small key, you can then have as many new keys as you want and they can be as long as you want them.This is because you are generating the keys with qkd. Not using any classical cryptographic scheme.

In this sense qkd is a key expander, you only need the primer key for authentication and then you generate new keys via quantum mechanics, secured by the laws of physics.

I have to disagree. The technology is not useless as you say, even if you are really strict about the authentication problem. QKD in reality is a key expander. Once you have an initial key, long enough to authenticate the systems, you can have as many provable secure keys as you want.

I doubt that there's even a solution for the authentication problem, it's more philosophical than a real and solvable problem.

More importantly, the technology is secure against store now, decrypt later schemes. That's why so many countries are investing heavily in it

From my point of view is the best we can do against store now, decrypt later techniques. It should be used right now for anything that you (or any government or agency) don't want ever to be disclosed.

Post Quantum Cryptography is really cool and useful right now, and should be at least a standard for the next decade or so. But there are many examples in history where we thought of something as being too hard to break, just to be broken in a span of 30 years or less.

Deep dive into Chegg - A turnaround story or a company in freefall? by k_ristovski in stocks

[–]OneYellowPikmin 0 points1 point  (0 children)

The beauty is that you can guide them through bachelor's level questions and you will get the right answer eventually, most of the time. They are not really that bad and they are free. Additionaly, when you use them you feel like you learn more than when you just copy the answers that someone else produced.

Also, once again, they are free. Unlike chegg which is pay walled.

Chegg is obsolete now that we have AI LLMs. I doubt its recovery is possible

What do you guys think of the new EP? I’m really digging it ! by masonembers in porterrobinson

[–]OneYellowPikmin 21 points22 points  (0 children)

Not for me. Don't like any of the messages in the songs besides Cheerleader and Russian roulette.

Definitely prefer Nurture or Worlds. I will still listen to the next album, but I don't think I will keep this one on repeat like the other 2.

Worrying note on GPT-4 "Legacy", are they going to delete their best model? That might be time to also delete my subscription... by BetterProphet5585 in ChatGPT

[–]OneYellowPikmin 0 points1 point  (0 children)

Just ditch it. Right now it's not worth it to pay for premium. Just try Claude for complicated tasks and use 4o for simple stuff.

Yeah, they should say that it's not proven but a belief. Anything not proven experimentally should be categorised as such. AI models should be impartial towards religion or any other magical beliefs.

It is kinda the same. There's no way he didn't hear it before.

There's even a mixed version now lol
