Some reading on quantum computing timelines:

As per their 2008 estimate, business-level quantum computing is about 10 years away.
After the business-class solutions, it's just a matter of 5-10 years for PC co processors. Most computer development has been like that - you'll see a business-level solution for $10,000 then in 5 years, the public market will have it for about $1k or so (I remember HDDs were that way).
Back from the dead, I'm afraid.
