Optical systems are promising candidates for the implementation of quantum computation protocols involving many qubits, or many qu-modes in the continuous variable case. Recent technological progresses have allowed to create and individually squeeze several modes of the electromagnetic field (either spatial or temporal) in a cavity [1]. These squeezed modes can be mixed by linear optic networks to...
Quantum information has reached a stage where real-world applications stimulate an intense research for the implementation of reliable and practical protocols for quantum communication and information processing. The implementation of such protocols, though, requires distributing quantum correlations (entanglement) among a number of degrees of freedom (modes) increasing with the complexity of the...
We demonstrate a novel trustworthy witness for single-photon entanglement based only on local homodyne measurements. This operational test is well suited for quantum networks, and highlights the potential of the optical hybrid approach.
The evolution of systems during operational lifetime is becoming a core assumption of the design. This is the case for resource constrained embedded systems. Such an evolution may be driven by environment or the execution context. The adequacy of the service delivery with respect to the current operational conditions depends on the ability to tune the software configuration accordingly. This is true...
The separation of concerns provided by reflective architectures is of high interest for the development of dependable systems. Beyond this initial interest, the use of this technology remains questionable due to the lack of work reporting on validation aspects. This paper defines an incremental strategy for testing the cornerstone of the reflective architectures that we consider, i.e. the MetaObject...
