I have been experimenting with IBM Q Experience for almost 4 months now. On Day 1, I created a free account, learned some really basic OpenQASM, and then entangled electrons.

Two days ago, I created a free account with D-Wave. I’m not done with quantum computing, I just want to see for myself what quantum annealing can and cannot do. On Day 1, I created a free account and downloaded a bunch of PDF files. I haven’t actually done anything with it yet because I seem to have quite a bit of reading to do first.

While exploring D-Wave, I figured I’d multitask and get ready to explore other quantum computing companies’ offerings, starting with Rigetti.

A waitlist? Well, that’s different.

How about IonQ?

An invite list?!?!? That sounds even worse that a waitlist!

So, thus far, IBM Q Experience makes the best first impression. It is the quickest and easiest way to get started with quantum computing. Although I’m not done looking into other providers, it looks like competitors will have quite a challenge making as good a first impression.
