Quantum computer dominates traditional PC in head-to-head battle

Computer scientists have been singing the praises of quantum computers for years but the question remains: How do they stack up against a traditional high-end PC? We finally have an answer to that question as Catherine McGeoch from Amherst College,...

D-Wave said they would prefer to spend their time convincing customers that they have a system that can solve problems more efficiently rather than wasting time on academic benchmarking. Developing real-world applications is much preferred.
Careful there guys.... while this sounds like it makes a lot of sense not to 'waste' time on those benchmarks, there's a pretty useful place for them. It's called Proof of Concept. At some point some investor is going to want to know if the money is being spent on something worthwhile or just a theory. Putting together a decent benchmark to show off your new computer might result in a lot of funding. Or not.

The qubits don't just pop out 0's and 1's at the same time. They pop out 0, 1 and everything in between them at the same time. This is great if you need fuzzy logic type stuff, but you're going to get a different answer every time you computer logical numbers like 1 + 1 = 2.

Lockheed Martin has already said it works and they're investing on upgrading their D-Wave. [link]

I read an article by MIT that talked about a Lenovo Workstation vs a Quantum computer at computing tasks. The Quantum computer was 1000x faster. It was a quadcore CPU only in the workstation. We need the Quantum computer to go head to head against dual 8 core Xeons to prove the quantum computer superior.

Hell with 8 core, it needs to go up against Watson or any other supercomputer.

...but if it could receive more than one bit of information at a time the only bottleneck will be the speed if the Internet connection. Better yet, if internet providers use quantum computing we can have instant downloads of very large files.

@guest^, a computers speed doesnt necessarily reflect how fast you download something...
perhaps ISP's using these server side could provide us with more bandwidth for a cheaper price. On top of that, with entanglement in modems the data could be transferred instantly. Just imagine, an end to lag. I'm sure this would also be great for brokerages and day where the speed of light "isn't fast enough."

Hmm. Maybe.

I was just getting pissed over a captcha being hard to read when I thought, "I need a quantum computer for this...". They'll be great at deciphering visual object.

It can both run and not run Crysis simultaneously.
That was the best "can it run crysis" comeback ever. *slow clap*

with entanglement in modems the data could be transferred instantly.
And at any distance in real time. You could be on Mars and talk to your kids without a delay.
