Is the ‘quantum singularity’ near?

According to Dove, some in the quantum-computing community have suggested that Aaronson and Arkhipov’s experiment may be difficult enough to perform with the requisite number of photons that researchers would be better off trying to build full-fledged KLM systems.But, Dove says, “One of the ways that Scott and I like to pitch this idea is as an intermediate step that we need to do KLM.” Building a KLM optical quantum computer would entail building everything necessary to perform the Aaronson-Arkhipov experiment — plus a bunch of other, perhaps even more challenging, technologies.

Human brain, Internet, and cosmology: similar laws at work?

Having the ability to predict — let alone trying to control — the dynamics of complex networks remains a central challenge throughout network science. Structural and dynamical similarities among different real networks suggest that some universal laws might be in action, although the nature and common origin of such laws remain elusive. “These findings have key implications for both network science and cosmology,” noted Krioukov. “We discovered that the large-scale growth dynamics of complex networks and causal networks are asymptotically (at large times) the same, explaining the structural similarity between these networks.” “The most frequent question that people may ask is whether the discovered asymptotic equivalence between complex networks and the universe could be a coincidence,” said Krioukov. “Of course it could be, but the probability of such a coincidence is extremely low. Coincidences in physics are extremely rare, and almost never happen. There is always an explanation, which may be not immediately obvious.”
