EXCERPT: Physicists are racing to complete a new model of quantum complex networks that tackles the physical nature of time and paradoxical features of emergence of classical reality from the quantum world. [...] About 15 years ago, physicist Albert-László Barabási, now at Northeastern University while studying the complexity of the World Wide Web, created a network model to illustrate how a relatively small number of websites receives the majority of browsing hits, while the majority of sites on the internet share the remaining amount of traffic. This and related realizations led to the development of a whole new branch within the field of network science and is based on the idea that social and biological networks follow non-random patterns. (See "Embracing Complexity.") But can aspects of quantum physics be expressed in terms of a quantum theory of complex networks? Theoretical physicist Jacob Biamonte is now grappling with that question. If successful, this new line of thinking could help explain how familiar everyday physics—and even time’s arrow—emerge from the fuzzy quantum realm...
