  Quantum computing holds great promise to solve to problems where classical
computers cannot reach. To the point where it already arouses the interest of
both scientific and industrial communities. Thus, it is expected that hybrid
systems will start to appear where quantum software interacts with classical
systems. Such coexistence can be fostered by service computing. Unfortunately,
the way in which quantum code can be offered as a service still misses out on
many of the potential benefits of service computing. This paper takes the
traveling salesman problem, and tackles the challenge of giving it an
implementation in the form of a quantum microservice. Then it is used to detect
which of the benefits of service computing are lost in the process. The
conclusions help to measure the distance between the current state of
technology and the state that would be desirable in order to have a real
quantum service engineering.
