Surely you're not going with that tired old joke?

It's a hell of a lot more interesting than blockchain. Even if it can only solve certain kinds of problems, it can solve those very quickly.

bostonguy: BLOCKCHAIN IS MORE THAN JUST A DIGITAL LEDGER


It is. It's a very poorly designed distributed ledger. No one in their right mind would allow arbitrary data to be included in a Ledger, for example. Not would they need decentralization in full. You'd just have a central master (even if redundant) and transactions  fielded by distributed servers.

But decentralization sounds cool to people who don't trust the government or corporations, but themselves are definitely completely and totally trustworthy.

Net neurality seen crying in the corner.

Corporations are people too ya know, why dont these writers ever consider the corporation's feelings in these articles?

I always ask interviewees if they are familiar with the "Quantum Blockchain" SW pattern. I love the answers of those that try to BS

Well, the writer admits to being completely tied to Facebook, Twitter, Instagram, etc, and is of a mind they should be public utilities.

While the INTERNET as a whole could certainly be, and I'm happy to discuss nationalizing ISPs, as someone whose been online for years, those stupid platforms are not utilities and don't need to be nationalized. Newspapers weren't, Magazines weren't. TV wasn't.

CSB: About seven years ago we hosted an exchange student from Italy. Kid was a freaking genius. No exaggeration, he taped sheets of butcher paper to his bedroom walls and wrote equations on them like he was part of The Big Bang Theoryor something. Took him on a tour of Fermilab and he was in his like a kid in a candy store. While I could understand about half of what they were talking about, he started asking questions of our guide (one of the scientists working there) that would actually make them pause and, in one case, bring in an associate.

Today he is working on his Master's thesis in quantum computing. He just came back to visit us for Thanksgiving. While he was here he spent a lot of his time working on his paper. He shared with me the beginnings of his paper.

Title:
Quantum walks with time-dependent Hamiltonians and
their application to the search problem on graphs.


Abstract:
In this thesis we study the properties of quantum walks with time dependent Hamiltonians, focusing in particular on the application to the quantum search problem on graphs.
We compare the time independent and the time dependent approach for two graph topology, the circular and the complete graph, which represents respectively the worst and best case scenario for the known quantum search. We also investigate the role of the function that regulates the time dependence of the Hamiltonian in the time scaling at which the solution is found.
Lastly we exploit the consequences of the adiabatic theorem to study the localization properties of the time-dependent approach and give some results in terms of robustness.


I'm not an idiot but this doesn't even seem like English. Before he even got to the equations my brain turned into tapioca pudding and I felt like Tic Tac Toe would be taxing my mental faculties.

If quantum computing is so real, then why aren't these big brains pointing that shiat at dormant / during development BTC wallets?   Y'know, those giant abandoned wallets with thousands of BTC.  A proper quantum computer should be able to break the keys and be able to sign new transactions with them.  It would self-fund decades worth of research, or entire weeks of cryptobro cocaine benders.

I suspect it's because its full of horseshiat, and the current ones are just traditional computing done over a layer of indirection/assumptions.

That is excellent. Someone needed to do that.

No idea what this means.
