On the adiabatic limit of Hadamard statesSep 10 2016We consider the adiabatic limit of Hadamard states for free quantum Klein-Gordon fields, when the background metric and the field mass are slowly varied from their initial to final values. If the Klein-Gordon field stays massive, we prove that the adiabatic ...

If the Klein-Gordon field stays massive, we prove that the adiabatic ... More Long-distance quantum key distribution with imperfect devicesOct 30 2012Apr 08 2013Quantum key distribution over probabilistic quantum repeaters is addressed. We compare, under practical assumptions, two such schemes in terms of their secure key generation rates per quantum memory. The two schemes under investigation are the one proposed ... More Long-Distance Trust-Free Quantum Key DistributionJul 30 2014Nov 25 2014The feasibility of trust-free long-haul quantum key distribution (QKD) networks is addressed. We combine measurement-device-independent QKD (MDI-QKD), as an access technology, with a quantum repeater setup, at the core of future quantum communication ... More Ribbon Graphs and Mirror Symmetry IMar 12 2011Given a ribbon graph $\Gamma$ with some extra structure, we define, using constructible sheaves, a dg category $CPM(\Gamma)$ meant to model the Fukaya category of a Riemann surface in the cell of Teichm\"uller space described by $\Gamma.$ When $\Gamma$ ... More Fault-Trajectory Approach for Fault Diagnosis on Analog CircuitsOct 25 2007This issue discusses the fault-trajectory approach suitability for fault diagnosis on analog networks. Recent works have shown promising results concerning a method based on this concept for ATPG for diagnosing faults on analog networks. Such method relies ... More Phase estimation via quantum interferometry for noisy detectorsJul 19 2011Oct 12 2012The sensitivity in optical interferometry is strongly affected by losses during the signal propagation or at the detection stage. The optimal quantum states of the probing signals in the presence of loss were recently found. However, in many cases of ... More The multiplex dependency structure of financial marketsJun 15 2016We propose here a multiplex network approach to investigate simultaneously different types of dependency in complex data sets. In particular, we consider multiplex networks made of four layers corresponding respectively to linear, non-linear, tail, and ... More Liquid-Liquid Phase Separation in an Elastic NetworkSep 01 2017Sep 27 2017Living and engineered systems rely on the stable coexistence of two interspersed liquid phases. Yet surface tension drives their complete separation. Here we show that stable droplets of uniform and tuneable size can be produced through arrested phase ... More Network-based indicators of Bitcoin bubblesMay 11 2018The functioning of the cryptocurrency Bitcoin relies on the open availability of the entire history of its transactions. This makes it a particularly interesting socio-economic system to analyse from the point of view of network science. Here we analyse ... More The design of the MEG II experimentJan 15 2018The MEG experiment, designed to search for the mu+->e+ gamma decay at a 10^-13 sensitivity level, completed data taking in 2013. In order to increase the sensitivity reach of the experiment by an order of magnitude to the level of 6 x 10-14 for the branching ... More
