What is QBit and how soon can I get a quantum computer?

Question

How soon can I get a quantum computer? Is there any way to build a simple one? How old are they for early followers?

I would like to understand from a high level what QBit is, how many states it can have and what types of algorithms will work well in this arena.

Answer 1

Over the past ten or two years, there has been a lot of hype around quantum computers, but there are a number of problems that will need to be addressed before they become practical.

I recommend this short 24-minute video and D-Wave Wikipedia article for a quick overview, and there are many more resources on this blog written by the founder and CFO of D-Wave.
