#condmat — Public Fediverse posts

All interesting physics is decentralized and local. If there was a central algorithm deciding what physics is allowed, we wouldn't have the enormous diversity and beauty of the universe emerging out of something like two dozen fundamental physical constants.

I think this decentralized nature is also important when trying to understand physical systems. When we came up with our definition of topological order based on error correction (https://doi.org/10.1103/PhysRevB.106.085143), it was absolutely crucial to use a decentralized algorithm and not a centralized one where you feed in the positions of all errors at once. It's the fediverse approach to error correction, if you like.

Topologically ordered states of matter are characterized by fascinating non-local quantum correlations in the many-body wave function. However, deciding whether a quantum state is topologically ordered or not is extremely difficult. A large part of the problem is that so far, signatures like the topological entanglement entropy could not be efficiently computed.

We are happy to present a framework for the computation of topological order that provides an exponential speedup over existing methods: https://dx.doi.org/10.1088/1367-2630/ae3598
