Hardware, Embedded Systems Quantum computers could become a reality very soon, opening up some fantastic possibilities -- including tele-portation, says Richard Gray.

So basically, we can hope for a QPU with a RNG and Q(uantum)Sort for our next 128 cores silicon-based CPU but we shouldn't dream of running programs off it.
I'll put my bets on biochemical computers then. After all, we have a working model in our heads.

What is in your head can't crack a 32bit RSA key in hours, in days or in years.
Studying the brain is quite interesting for curing deseases, but I very sceptical when it comes to computer applications. If what was needed was a brain, we could as well use ours. If we have computer, it is to overcome our brain limitations. No human brain can break a 64bit RSA key in its life time. That is what computers are for.

Actually, I think it is feasible for a human to factor a 32-bit number, so you could crack 32-bit RSA key in your head.

Human brains might not be great at factoring huge numbers or doing rapid computations, but they are the *BOMB* at pattern recognition, and whether you realize it or not, it actually takes a great deal of "operations", so to speak, to accomplish this.

You seem to underestimate what your brain is doing at all times.
Our abstract thought abilities are a new feature implemented over many layers of cruft.
That you are able to detect movement, identify objects and calculate trajectories in realtime while keeping your body in the right position is already an amazing feat. But this is only the task on focus. At the same time, the brain is polling your tastebuds, your skin, your nose; everything for relevant input. A current supercomputing cluster cannot cope with all the information processing in a fly's brain.
In addition to that, the amount of useless information you store analogically without even realizing would set the Google servers in flames.
Silicon could possibly be faster, we don't have the benchmarks, but it surely doesn't scale well even if it beats QC at that. A 3D CPU with a few million cores would melt its way to the Earth's nucleum well before processing anything.
