Clouds of Quantum Machines
INTRODUCTION
This work is a continuation of studies started at
2014. Since then, I improved some ideas about
theoretical quantum machines interacting in cloud
operation, as well as enhancements on the concept
of quantum entanglement itself. Some recent
works have been added to the original references,
although the classic treatises remain in effect, given
the slowness with which the subject progresses.
As we know, one of the great challenges in
quantum computing is how to preserve quantum
entanglement, since microphysical systems are
extremely sensitive to external disturbances. It
is one of my aims to show a way to minimize
this problem. Moreover, a quantum orchestration
metalanguage is introduced into a first schematic
representation of the operation of a quantum
cloud aiming to optimize further constructions of
quantum algorithms. While it is essential that the
reader becomes familiar with quantum mechan-
ics, some parts of my first work are reproduced
here in order to reduce the effort to understand
the subject.
BACKGROUND: SERVICES
AND CLOUDS IN A
CONTEMPORARY APPROACH
Services are cybernetic replicas of human prac-
tices, being evoked by well-established environ-
mental motivations. In turn, SOA is an architecture
that integrates in a standard manner several service
units, each of them sending their features as sets
of tasks over the network. Only service interfaces
are exposed to consumers as exported methods
(Nakamura et al., 2004). Therefore, when services
are requested, SOA seeks the best responses to
those environmental motivations according to the
internal logic of each service. In particular, this
architecture is now strongly linked to the theme
of “enterprise application integration” (EAI)
in contexts where legacy applications already
established are performed on different platforms.
The literature on SOA comprises several mile-
stone contributions as the works of Nakamura et
al. (2004), Erl (2005), Anderson & Ciruli (2006),
Natis (2007), Sha (2007) and, markedly, Frenken et
al. (2008) about device-level service deployment.
On this latter subject, it is noteworthy that, in the
process of architectural development, devices
which access legacy applications are created and
interact using a protocol defined by the system. In
turn, the system returns the aggregated information
from the various legacy applications, preferably
without any additional code. The architectural de-
velopment also takes care of the service interface,
prescribing the information required to access the
competences of that. It is worth remembering that
the existence of interfaces and descriptions of ac-
cessibility is sine qua non for the implementation
of SOA. More recent works show the state-of-art
in services orchestration (MEF Forum, 2015;
Lemos et al., 2015).
In SOA projects, the so-called Enterprise
Service Bus (ESB) is thought to be the main
component of the infrastructure layer. It is the
mediator between provider and service consum-
ers, and its responsibility is to provide integration
and interoperability between different systems.
Embedded in this responsibility is also the mission
of cleaning the databases by a service that tracks
and recognizes all of the systems which shall be
linked. Connectors are created in the databases
