Where are we in Quantum Technologies?

It is often that we see news related to Quantum Computers, or new emerging companies which invest in quantum research areas promising the emerge of the most sophisticated technologies. I have also read that teleportation could be feasible in the near future. But, where are we actually in all this? Can we think that quantum computers will be sold in any store in the next years? Unfortunately the reality is far from that.
