It depends on what you mean by possible. We've run very tiny quantum programs already, such as factoring 15 into 3 and 5, but it's been difficult to scale this

It depends on what you mean by possible. We've run very tiny quantum programs already, such as factoring 15 into 3 and 5, but it's been difficult to scale this upwards and work on larger numbers of bits at a time. So, possible? Yes, for sure. Practical.... Not quite yet, maybe never, maybe soon.
