Continuous-variable state moments from randomized homodyne and heterodyne measurements
Michael Tsesmelis, Moritz Straeter, Leong-Chuan Kwek
Continuous-variable (CV) quantum states are naturally characterized by their moments, defined as expectation values of products of single- or multimode ladder operators. Many CV Ha…
Detecting entanglement of non-Gaussian continuous-variable states from single-copy homodyne measurements
Moritz Straeter, Michael Tsesmelis, Leong-Chuan Kwek
The entanglement of Gaussian continuous-variable (CV) states is fully determined by the state's second moments. In contrast, some entangled non-Gaussian states evade every second-m…
TechRank
Anita Mezzetti, Loïc Maréchal, Dimitri Percia David +5
We introduce TechRank, a recursive algorithm based on a bi-partite graph with weighted nodes. We develop TechRank to link companies and technologies based on the method of reflecti…
Identifying Emerging Technologies and Leading Companies using Network Dynamics of Patent Clusters: a Cybersecurity Case Study
Michael Tsesmelis, Ljiljana Dolamic, Marcus Matthias Keupp +2
Strategic decisions rely heavily on non-scientific instrumentation to forecast emerging technologies and leading companies. Instead, we build a fast quantitative system with a smal…
TechRank: A Network-Centrality Approach for Informed Cybersecurity-Investment
Anita Mezzetti, Dimitri Percia David, Thomas Maillart +2
The cybersecurity technological landscape is a complex ecosystem in which entities -- such as companies and technologies -- influence each other in a non-trivial manner. Measuring…
