For those of you who like to see science fiction as it approaches, The Next Big Future has a roundup of tech stuff that is moving beyond the talked-about stage to the startup stage. Remember that if even a third of these pan out, it's a whole new world. The fusion and the quantum computers really caught my eye.
Instapundit, as usual for these things.
Quantum computers aren't nearly as cool as everybody seems to think they are.
ReplyDeleteIn particular, they're not nearly as fast as the legend would have it.
There are a certain class of algorithms that run exponentially faster on a quantum computer, but that class is quite small, and quantum computers definitely cannot solve the classically 'hard' problems (NP-hard) in polynomial time.
