A quantum computer installed, or contracted for installation, at a named host outside the vendor's own premises: .
Included: systems online, and systems on order under a signed contract.
Not included: cloud-only access, which has no location; machines in a vendor's own lab or data centre; memoranda of understanding and framework agreements; desktop teaching units, such as two- and three-qubit NMR machines.
Every entry links to its source: the host's own announcement first, then the vendor's, then a government's. Where only press coverage exists, the entry is marked reported.
Online means the host or vendor says the system is in use; planned means contracted and not yet in use. The year is the year of installation, or for planned systems the year announced for it.
System names and qubit counts are as published, never estimated; where none is published the field is blank.
A filled dot is a system online, a ring a system on order. Colour is the qubit modality:
Zoomed out, a marker per region or country gives the count, its ring split by modality. Zoomed in, each system has its own dot. A black point joins the systems of one host; click it for the list. A grey point marks a city with several hosts.
