The Impact

This theoretical article studies the bearings of cloud computing under the impact of quantum mechanics in the field of information processing, considering quantum entanglement as an essential physical resource to deploy intelligent behavior in server clouds. It proposes a “beehive” model of cloud after the introduction of the concept of spontaneous quantum entanglement in Service-Oriented Architectures (SOA). Also it proposes a way to represent the creation of entangled states of information, introducing the concept of progenitor.

This chapter continues previous studies in service-oriented architectures (SOA) on clouds of quantum computers, considering quantum entanglement and quantum teleportation of states of services as resources to deploy high production in IT environments and to guide studies on the implementation of intelligent behavior in server clouds. A way to preserve quantum entanglement is presented. Also, the chapter proposes a metalanguage to organize the topology of orchestration of services. This topology is embedded in the states of services and takes part in the information to be teleported from server to server. The creation of entangled states of information with the aid of the concept of progenitor is reviewed with some details.

The Impact

When Alice and Bob share two pairs of quantum correlated states, Alice can remotely prepare quantum entanglement and quantum discord in Bob’s side by measuring the parts in her side and telling Bob the measurement results by classical communication. For remote entanglement preparation, entanglement is necessary . We find that for some shared resources having the same amount of entanglement, when Bell measurement is used, the entanglement remotely prepared can be different, and more discord in the resources actually decreases the entanglement prepared. We also find that for some resources with more entanglement, the entanglement remotely prepared may be less. Therefore, we conclude that entanglement is a necessary resource but may not be the only resource responsible for the entanglement remotely prepared, and discord does not likely to assist this process. Also, for the preparation of discord, we find that some states with no entanglement could outperform entangled states.

Fully Functioning

Quantum computing, a fancy word resting on equally fancy fundamentals in quantum mechanics, has become a media hype, a mainstream topic in popular culture and an eye candy for high-tech company researchers and investors alike. Quantum computing has the power to provide faster, more efficient, secure and accurate computing solutions for emerging future innovations. Governments the world over, in collaboration with high-tech companies, pour in billions of dollars for the advancement of computing solutions quantum-based and for the development of fully functioning quantum computers that may one day aid in or even replace classical computers. Despite much hype and publicity, most people do not understand what quantum computing is, nor do they comprehend the significance of the developments required in this field, and the impact it may have on the future. Through these lecture notes, we embark on a pedagogic journey of understanding quantum computing, gradually revealing the concepts that form its basis, later diving in a vast pool of future possibilities that lie ahead, concluding with understanding and acknowledging some major hindrance and speed breaking bumpers in their path.

Service Level Agreements (SLAs) are nowadays used as a cornerstone for building service-oriented architectures. SLAs have been closely investigated in the scope of distributed and Grid computing and are now gaining uptake in cloud computing as well. However, most solutions have been developed for specific purposes and are not applicable generally, even though the most approaches propose a general usability. Only rarely have SLAs been applied to real-time systems. The purpose of this chapter is to analyze different fields where SLAs are used, examine the proposed solutions, and investigate how these can be improved in order to better support the creation of real-time service-oriented architectures.

Implementing Single Sign-On (SSO) in a Cloud space for a spectrum of services and applications is an interesting research avenue for scientific communities in the field of secure identity and access management for Cloud Computing. Using an SSO implementation, in the backend, users can navigate any or all of the supported applications or resources without the need to repeatedly provide credentials. In this chapter, the authors present an efficient and robust Cloud Single Sign-On Architecture (CSSOA) model based on a token security mechanism. Service Oriented Architectures (SOAs) are one of the enabling technologies for solving complex service oriented real world challenges, and hence, CSSOA has been implemented using SOAs. In the authors’ CSSOA model, a CSSO SOAP authentication service is distributed among the Cloud servers while the CSSO database service is centralized.

Bipartite Entanglement

Entanglement is one of the most useful resources in quantum information processing. It is effectively the quantum correlation between different subsystems of a composite system. Mathematically, one of the most hard tasks in quantum mechanics is to quantify entanglement. However, progress in this field is remarkable but not complete yet. There are many things to do with quantification of entanglement. In this review, we will discuss some of the important measures of bipartite entanglement.

The Impact

A major advantage of Service-Oriented Architectures (SOA) is composition and coordination of loosely coupled services. Because the development lifecycles of services and clients are de-coupled, multiple service versions must be maintained to support older clients. Typically versions are managed within the SOA by updating service descriptions using conventions on version numbers and namespaces. In all cases, the compatibility among services descriptions must be evaluated, which can be hard, error-prone and costly if performed manually, particularly for complex descriptions. In this paper, the authors describe a method to automatically determine when two service descriptions are backward compatible. The authors describe a case study to illustrate version compatibility information in a SOA environment and present initial performance overheads. By automatically exploring compatibility information, a) service developers can assess the impact of proposed changes; b) proper versioning requirements can be put in client implementations guaranteeing that incompatibilities will not occur during run-time; and c) messages exchanged in the SOA can be validated to ensure that only expected messages or compatible ones are exchanged.
