This paper presents a number of service-centric platforms and demonstrations that have been developed by the FP7 Autonomic Internet project with the aim to create a flexible environment for autonomic deployment and management of Virtual Networks (VN) and Services as validated on large-scale testbeds.
The current internet is commonly perceived as being too inflexible. Network Virtualization has been recognized lately as a method to overcome these limitations. Previous implementations of Virtual Network (VN) deployment software either provided limited access to the network layer (like PlanetLab), or focused only on specific application scenarios (like VNUML or VLAN). A first step toward the expected...
We provide a basic introduction of the core ideas and theory surrounding fault-tolerant quantum computation. Quantum fault-tolerance essentially refers to avoiding the uncontrollable cascade of errors caused by the interaction of quantum-bits. The presented concepts underlay the theoretical framework of large-scale quantum computation and are the driving force for many recent experimental efforts...
The realisation of large-scale quantum computing is no longer simply a hardware question. The rapid development of quantum technology has resulted in dozens of control and programming problems that should be directed towards the classical computer science and engineering community. One such problem is known as Pauli tracking. Methods for implementing quantum algorithms that are compatible with crucial...
Various emerging technologies promise advantages with respect to integration density, performance or power consumption, at the cost of approximate or probabilistic behavior. Approximate computing, where limited computational inaccuracies are tolerated at the system or application level is therefore of increasing interest. This paper investigates the use of stochastic computing (SC) as a tool for approximate...
Topological quantum computing has recently proven itself to be a very powerful model when considering large-scale, fully error corrected quantum architectures. In addition to its robust nature under hardware errors, it is a software driven method of error corrected computation, with the hardware responsible for only creating a generic quantum resource (the topological lattice). Computation in this...
A new approach to detecting and diagnosing faults in quantum circuits is introduced. In order to account for the probabilistic nature of quantum circuits, collections of test experiments, called binary tomographic tests (BTTs), are generated. A BTT can identify a fault with respect to some user-defined confidence threshold τ. We present an algorithm to generate BTTs that either detect, or ensure the...
Some emerging technologies for building computers depend on components and signals whose behavior, under normal or fault conditions, is probabilistic. Examples include stochastic and quantum computing circuits, and conventional nano electronic circuits subject to design, manufacturing or environmental errors. Problems common to these technologies are testing and validation, which require determining...
It is widely accepted that the network of the future will require a greater degree of service awareness and optimal use of network resources. This article presents an architectural design for an open software-defined network infrastructure that enables the composition of fast and guaranteed services in an efficient manner and the execution of these services in an adaptive way, taking into account...
