From what I have learned about quantum computing I don't think we are going to see one in our cell phones any time soon, if ever. That may change but seems unlikely given the way our portable devices are used today.

Here's a primer on quantum computing that I found helpful, with a interesting comment about application near the end. Hope this is helpful, Andrea.
