Comment Makes no sense (Score 4, Insightful) 222

So the number of continuous parameters describing the state of such a useful quantum computer at any given moment must be at least 2**1,000, which is to say about 10**300. That's a very big number indeed. How big? It is much, much greater than the number of subatomic particles in the observable universe.

I am struggling to come up with some way that this part makes any sense at all. It sounds like the kind of thing someone who is definitely not an expert the area would say. He is expressing the number of possible configurations of 1,000 qubits but that is only something you care about if you are simulating a quantum computer with a classical one. The whole point of quantum computers is that you don't have to do that.

Also a simple counterexample to this sentiment is given later on, when mentioning that Google already has a 72-qubit computer. Just storing the states of a 72-qubit machine would be substantially more than the entire capacity of the internet, implying that since we somehow did it then enumerating all the states is not necessary.

If you are only hiring whoever is best for the job then you are probably hiring a lot of foreign workers that will do it for way less money. Should the government allow that to happen or do you believe in hiring laws when they protect you?

Also, if you are running your company with only the end goal in mind then you are probably doing something illegal. Laws exist to protect the interests of society, not the interests of individual companies or people.

Nope, the problem is that an adversary can send you a carefully crafted email, which inside of it has an old encrypted email that they want to break into, and due to automatic decryption and rendering of HTML elements the plaintext of that encrypted email gets exfiltrated to a target server. The core issue is actually in the way MIME works with multi-part emails where you are allowed to have some unencrypted HTML and some encrypted segments together in the same email.

No, no, no. A thousand times no. Information theoretic security means that no matter how much computational power you have you cannot break it, because you are fundamentally missing some information that is necessary to determine a unique solution. RSA is not that. No ciphers in use are that, except the OTP.

This TLS is a bad idea. Whoever thought about it assumes that there is a private key known only to the certificate authority. What if for some reason a third party finds this key or accesses it remotely? Suddenly, all communications, including the ones of the morons who came up with the idea, will be wide open to everybody.
