They're definitely referring to a real ("universal") quantum computer, not the quantum annealing devices of D-wave. Their computer will be able to run the Schor algorithm, if it is as advertised. If they have 20 qubits in two months, as they say they will, that seems like great progress compared to where I thought the field was. And if they have 50 within a couple years after that, it would be huge. One caveat is the…

You say " If they have 20 qubits in two months" and " if they have 50 within a couple of years". Doesn't the article say that they have 50? I'm unclear on this, because I have yet to see a published result talking about running Shor's algorithm on a quantum computer beyond the NMR-based physical simulation and the adiabatic one (which is just annealing). What exactly is IBM claiming to have done here?

They're simulating 50; they're implementing 20.

Presenting the pictures of a quantum computer with adbobe flash is an impressive combination of technologies. I hope they are use a different technology stack to develop the OS of that machine ;-)

Looks like their publishing platform is that old that it's still using Flickr's Flash photo embedding widget.

TIL Flickr had such a widget.

The article appears to be saying that they are offering an actual quantum computer as a service, but as I recall, their previous offering was a simulation of a quantum computing environment. Yet, this same article refers to that thing as if it were a real QC. This makes me skeptical that the thing being offered here is a real quantum computer...Anyone here have any insight into whether this is legitimate?

Nothing specific to whether this claim is legitimate, but lately IBM has a tendency to make bold claims about tech that can't be backed up (e.g. Watson).

Let's be charitable: IBM marketing has that tendency.

IBM does still do some amazing research.

> It is estimated that 2048-bit RSA keys could be broken on a quantum computer comprising 4,000 qubits and 100 million gates. Experts speculate that quantum computers of this size may be available within the next 20-30 years. https://www.entrust.com/wp-content/uploads/2013/05/WP_Quantu... The paper is from 2009, so ~2030 to break 2048-bit RSA seems about right. If they can double the number of qubits every two years,…

From the Wikipedia timeline[1], it seems to be growing linearly. 1 - https://en.wikipedia.org/wiki/Timeline_of_quantum_computing

To quote my thesis advisor's terrible joke: "Everything's linear to first order"
