How scalable is quantum computing technology today?

Top Answer : What’s been demonstrated with quantum computers and their computing ability is mind-blowing. Google did a test for testing whether a number was a prime number. The most powerful supercomputer we have now would take about 10,000 years to do this computation. Google’s quantum computer did it in three hours and 20 minutes. This improvement in processing power is phenomenal.  I’m an applications guy. I want to see what it takes to actually get this thing in, get it working and have it do the job. That’s not saying that everybody is going to have quantum computers. But one thing I think that’s going to help, particularly with blockchain, is that a lot of companies now are looking at doing blockchain-as-a-service. Instead of having to do your own localized implementation for blockchain, if you have a Google provider that’s doing blockchain-as-a-service, they have access to the resources of a quantum computer to help with processing power. That helps a lot. It’s gonna cost a lot. But eventually, as it gets competitive, it’ll cost less.
