NetSci Satellite: Complex Quantum Networks


Topics of special interest to the satellite are:

  • Quantum communication networks
  • Detecting the presence of quantum effects in networks
  • Quantum network control
  • Quantum critical phenomena in complex networks

The satellite symposium will focus on theoretical aspects of complex network topologies appearing in quantum systems, as well as quantum algorithms on classical complex network topologies to strengthen the link between these diverse topics. ​
Networks are pervasive in nature and technology, offering a pertinent framework to study and understand a broad range of complex systems. Most research on networks has studied systems governed by classical correlations. These studies have revealed striking laws and patterns underlying a vast range of networks, in nature and society. Quantum mechanics is not only the most precise theory of nature, it also offers significantly stronger correlations between the nodes of a network, impossible to achieve classically. Ensembles of atoms or quantum information systems may be viewed as networks with quantum properties, being more and more accessible experimentally. Quantumness is not merely a necessary complication in our journey to advance current technologies. Merging classical challenges with quantum possibilities is believed to be transformative for both fields. Quantum approaches can be fundamentally more feasible and efficient to solve some hard problems than any known classical approach. Breaking classical security protocols through efficient factorization or enhancing database searches are just a few profound landmarks. On the other hand, our experience with classical networks can be a key in solving insurmountable issues with quantum networks, for instance their (lack of) scalability. Finding the topological guidelines and design principles to create scalable quantum networks is the principal challenge in both quantum computation and quantum communication.
