It is a bit more complicated then that. The only penalty to time is a constant factor if you are willing to use space proportional to the computation time. I did a bit of work on h…

Both ends of the experiment share entangled photons produced from a single source and sent both ways. The sender performs some operations and measurements on their two photons, i.e…

Quantum teleportation requires classical communication from the sender to the receiver of the state. Whether the teleportation itself happens faster then the speed of light is up t…

You are mostly correct. In fact the key strength of something like AES is realistically not even going to be reduced by half. In terms of the query complexity (the number of calls …

>I think LSD should be illegal Out of interest, why do you think this?

Attitude is correct. It refers to thusters controlling the orientation of the rocket. https://en.m.wikipedia.org/wiki/Attitude_control

This comes from deceleration of the capsule due to air resistance as it enters the atmosphere.

It is so good that even Alice can't decrypt those with confidence! :)

> Asymmetric crypto clearly is in NPcomplete To be in NP-complete a problem must both be in NP and every problem in NP must have a polynomial time reduction to it. This means that …

I think the issue is that the additional properties required for asymmetric key cryptography (as opposed to symmetric) are hard to gain without introducing some structure.

What do mean by this? I don't think complexity classes give any provable security to asymmetric cryptography. It cannot be proven that the difficulty of breaking any of the current…
