IBM unveils its first commercial quantum computer
At CES, IBM today announced its first commercial quantum computer for use outside of the lab. The 20-qubit system combines into a single package the quantum and classical computing parts it takes to use a machine like this for research and business applications. That package, the IBM Q system, is still huge, of course, but it includes everything a company would need to get started with its quantum computing experiments, including all the machinery necessary to cool the quantum computing hardware.
While IBM describes it as the first fully integrated universal quantum computing system designed for scientific and commercial use, it's worth stressing that a 20-qubit machine is nowhere near powerful enough for most of the commercial applications that people envision for a quantum computer with more qubits — and qubits that are useful for more than 100 microseconds. It's no surprise then, that IBM stresses that this is a first attempt and that the systems are "designed to one day tackle problems that are currently seen as too complex and exponential in nature for classical systems to handle." Right now, we're not quite there yet, but the company also notes that these systems are upgradable (and easy to maintain).
Quantum computers are real things, right?

I disagree.
This could be useful for CS departments to develop techniques for taking advantage of what computers like it can do. You have to have useful software tools together with the hardware to make the system useful, and this could help bootstrap the ecosystem while being used as a teaching or research tool.
Orgs with deep pockets that have a business case for the tech might wish to adopt early because of the potential advantage they see. This would help develop their applications in advance of the system being available so they can be a first mover as soon as one is, and they'll know what features it must have to be useful to them.
It is surely a tiny niche item though.
