Local circuits

…polynomial-time algorithm for circuits with uncorrected noise establishes limits on their possible quantum advantage. A second result shows that universal random-matrix behaviour can emerge exponentially faster than previously expected in local circuits and time evolution, with implications for benchmarking, cryptographic protocols and fundamental physics.

…They are: (i) emergent E-I dynamics in local circuits; (ii) how visual cortical neurons acquire their ability to detect edges and directions of motio
