or maybe machines with more than 34 qbits become self-aware?

Tech stuff for Kyle. 1970s should be fairly modern for him.

i expect they all got too accustomed to carte blanche spying on their populace to allow secure quantum communication.
this and it really wouldn’t be awesome if Iran, China, Best Korea, etc had the ability to instantly brute force AES-256 encryption. Or the Houthis.
The spying, yeah that sucks but actual terror organizations having the ability to idk open the flood gates at all the dams on the eastern seaboard … decidedly worse.

i think you are looking at this backwards. my thought was that quantum communication is secure, unhackable, and cannot be spied upon without the principals overtly granting access.
such being the case, the powers that be don’t want their peoples free from surveillance.

hmmm. hard for me to get worked up over ‘terror organizations’.
i could elaborate but you wouldn’t like it much.

yes, quantum comms are all sorts of Schrodinger’s cat … however a true Quantum computers ability to blast through existing X86_64 systems is the problem as it is in theory, trivial.
The world isn’t going to switch to Quantum computers instantly or perhaps ever. The likelihood you and I would ever own a quantum computer in our lifetime atm is extremely slim. Now this statement is one major breakthrough away from being a Gates like “nobody will need more than X memory” but as it stands, Quantum computing is extremely niche and requires multiple PHDs to even play pong.
A country with a significantly worse ideology to any/all Western nations having one though is, depending on who you believe, worse than a Nuclear exchange because, well, if existing key pair exchange encryption can be instantly broken it could involve a Nuclear exchange … remember Superman and The Office? What is stopping a bad actor from just taking everyone’s money? Forget about siphoning fractions of a penny, you could just move all the money and it would appear as a legitimate request. Shutting off power plants. Hacking into Teslas and sending cars off over passes. Hacking into autopilot systems, air traffic control, etc etc etc.
Anything that uses non quantum encryption may as well be unprotected.

So you’re not aware of the issues occurring in the Red Sea atm and how that is impacting trade? You can’t imagine how having the ability to break into port control systems, boat control systems, radar systems, etc etc could make this worse?
How about this, imagine what the CIA could do if their false flags appear as legitimate traffic originating from Iranian systems using legitimate Iranian users accounts that were broken into via brute force. All access and traffic logs would appear as legit.
You’re grossly missing the mark if spying is what you’re worried about here. They’re already spying on you.

I doubt terror orgs will have the ability to do that in the short term, but state actors likely will. And they can hang the threat of cyber attack over our head like they did nuclear missiles in the 20th century. Pretty sure the government, or what’s left of it, is analyzing the scenarios though now and moving toward a plan to recover in case such an attack happens.

Who’s funding the Houthis? Again, when you can break into existing X86_64 systems via brute force, instantly, you can’t reliably be tracked or stopped.
Iran could do a thing and pin it on anyone. Iran could make it look like the Democrats or Republicans were literally attempting a coup triggering a civil conflict. Y’all lack imagination as to what could be done if/when existing encryption is no longer an impediment. Now throw in AI and Deep Fakes. What if one of our boomer subs received an authenticated message from the President, they picked up a phone and called to speak to ‘the President’ to verify and it all checked out?
The possibilities are endless.

Calculate time taken to break AES key
A 256 bit AES key is required to be broken using the brute force method on a 2GHz computer. How long would it take to break the key in the best case and in the worst case situations? Assume that 1000
To put it another way: The Sun will die out in a paltry 5* 109 years. In that time, the ratio of the progress you’ve made to the total amount of work you have to do is within a couple orders of magnitude of the ratio of the mass of one hydrogen atom to the mass of the supermassive black hole at the center of the galaxy. However, Wikipedia lists the heat death of the universe as occurring at earliest in 10*100 (10 to the hundredth power) years, so you will crack it by then.
Illuminating?

I guess that even using a quantum computer it would take a few thousand years to break aes 256 key. Or a few seconds if you make a right guess.

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms
Federal agency reveals the first group of winners from its six-year competition
existing crypto algorithms may be vulnerable in a world where general purpose quantum computers exist. Jam’s link above is applicable to X86_64 CPUs. It is functionally impossible to brute force current algorithms which allows us to establish federated trust relationships knowing that who we want to have access can have access and we keep out everyone else. If this trust breaks down … its a very bad day.
Quantum computers don’t work on the same principles and have the ability to do some types of calculations significantly faster than we can today. Work has been underway for over a decade (that link highlights a 6 year contest) to attempt to make these algorithms resistant, and let’s hope they’ve done that. Problem is nobody really knows what quantum computers may be able to do since they’re still essentially lab only type machines.
for example, did any of you imagine the world you’re in now the first time you fired up quake 2 on your lets see back then celeron 300 or intel 333? think about all the advancements in languages, advancements in raw horsepower, GPUs, or the fact that your phone is significantly stronger than the computer you played quake 2 on.
we’re working to make the algorithms ‘resistant’ to what we think the first few generations of functional (outside of a lab) Quantum computers may be able to do. we have no idea how quickly quantum computing may advance though as now we have generative AI. What if you’re running GenAI on a Quantum stack? Can you iterate through the design process and go from a 1.0 product to 10.0 in a year or two? Nobody knows. If that were to happen though, the amount of power that would represent is pretty scary in the wrong hands … or even the right hands.
Imagine having the ability to take all the Lithu coins in existence and make it appear to the block chain to be valid requests.

you’re basing this assumption off what exactly? CPUs/GPUs today aren’t quantum computers. They’re significantly slower in the types of math cryptography requires, which is why crypto works.
Qbits aren’t bound by the same constraints.
