  • Central charge, a key quantity in conformal field theories, is crucial in the study of critical phenomena, yet its measurement has remained elusive. Here, the authors extract the central charge of several quantum critical models by accurately preparing their ground states on a superconducting quantum processor.

  • Topological quantum states can power fault-tolerant computing and solving classically hard problems. Here, authors create, measure and braid Fibonacci anyons on a superconducting processor obtaining golden-ratio and sample the anyon-free state to estimate chromatic polynomials.

  • Fast and reliable characterisation of quantum systems is a key part of quantum technologies development. Here, the authors propose and demonstrate a way to embed noise characterisation in classical shadow estimation of nonlocal properties, enabling an efficient way to extract information from noisy quantum systems.
