Today's Quantum Optics lecture is about quantum computing experiments, and how different types of systems stack up. Quantum computing, as you probably know if you're reading this blog, is based on building a computer whose "bits" can not only take on "0" and "1" states, but arbitrary superpositions of "0" and "1". Such a computer would be able to out-perform any classical computer on certain types of problems, and would open the exciting possibility of a windows installation that is both working and hung up at the same time.
There are roughly as many types of proposed quantum computers as there are people working on quantum computation. It's not clear which of them, if any, will eventually prove to be useful, meaning that this is the perfect subject for a blog poll:
The quantum computers of the future will be based on:(survey)
While this is a poll about quantum computing, the machines running the poll are strictly classical, so you can only choose one option.
