IBM Q backends have many different names, see for example this link. We have for example processors called Melbourne, Tokyo, Armonk etc.

I am curious where these names come from? For example, I know that IBM headquarter is placed in Armonk, NY. But what about others? Is there any special logic behind naming IBM processors?

The documentation states that "All quantum systems are given a city name, e.g., ibmq_johannesburg. This name does not indicate where the actual quantum system is hosted."

Some cities (e.g., Yorktown) host IBM Research centers.
