Quantum: Current State 2023 (Quantum pt2) - Computerphile

Continuing our look at the world of quantum, we're looking at the application of quantum technologies, from quantum cryptography to quantum computing. Victor V. Albert is a Theoretical physicist at University of Maryland and NIST.

This is extremely refreshing. He's not exagerating anything, only giving us the facts without hyping it up

[TheJimmyCartel]

Episode 2 would go a long way in this video title

Victor has this rare talent of using only as many words, and the best words, to still describe something in the most simple of ways. Awesome.

Dang it! You looked at the state of quantum. It was both working and not working at the same time and now they have to start all over again.

[nicksamek]

How do the classical algorithms compare to the quantum in terms of computing efficiency when looking at the computing/sim?

South Koreans published 2 days ago a second study confirming creation of room temperature super conductors (they already patented materials). If it's true, it seems like a breakthrough for commercial quantum computers based on superconducting circuits.

[Ziferten]

Take a drink every time he says "utilize"...

This video doesn't seem too useful. It's fine if one wants to learn the keywords to search in order to learn about quantum computers, but that's about it. There wasn't a single clear explanation in the video.

Superposition does not require discreteness. The Fourier transform wouldn't work if it were required.

"Classical cryptography" used to include permutation ciphers and (mono/poly)alphabetic substitution ciphers, some of which, like Enigma, required a machine, but not public-key ciphers. Now, if it can be done on a non-quantum computer, it's classical?

[HoSza]

"New classical stuff." Our compamy develops new and classical products. Customers get to choose one.

[brettbreet]

Interesting to note the superposition of misspelled letters on his paper. But despite many thousands of views, it appears the system hasn't collapsed into one discrete option! xD

[wipsypap]

It always comes with security/cryptography topics that an attacker 'just so happens' to eavesdrop on a communication. Can anyone point me to resources explaining the most common methods of eavesdropping on a line?

[cerealpeer]

and what does this say about undecidability in an increasingly complex problematic diametric

[alst]

This is all very fascinating but…does it run Doom?

[regbot]

Ok so now it became too wild. From a previous video I deduced that in case of superposition we can do a snapshot and we have a guarantee of getting some state with 50% probability (in the case presented in the video). It is logical. But this other thing, presented here, that allow us to get an info if somebody else did a snapshot? This is beyond my comprehension. I hope that somebody will eventually figure out some intuitive way of describing this.

I feel like there's always too much review in these kinds of videos that there's never any room for learning something new. Lots of videos already have what this video has

[Lion_McLionhead]

The big question is whether this is still the next big thing or if it's going the way of blockchains.

[vnews]

Use a Quantum computer to better engineer a regular computer.

[dinf]

the body language when he tries to put positive angle on things 🤣🤣🤣 yep, muh quantum computing gonna totally work all right 🤣🤣🤣
still, impressive that you got someone who actually talks about state of it honestly...
