Some of you really don't understand how this can and will solve real world problems such as cancer.

Sure in the most general terms, it is just a faster processor and overall system. But that's the whole point, isn't it?

Computers are not intelligent. They don't spontaneously solve problems. The reason they assist us in solving real problems is only because they are faster. We can program in the problem and variables to solving it and the computer can then run millions of possible solutions in seconds to find one that actually works.

Quantum computers can do that same process almost infinitely faster than the computers we have today. So solutions and automated tests on things like cancer, which take us currently months or years to run, would be done in fractions of seconds. Basically, it will take a process we're doing in decades, mere days.

So yes, it will solve real world problems because it is faster and capable of running far more complex problems. Imagine it running a real world weather simulation and helping determine how to literally stop tornadoes before they start. Japan, I think or maybe China, is currently doing that with traditional computers and it will take them a decade to really gain anything from it. With a Quantum machine, it might have already been done.

Don't underestimate the potential here with ridiculously narrow minded labels.
