Researchers at the National University of Singapore, the University of Crete in Greece, the University of California, Santa Barbara, and Google have simulated the energy spectrum predicted for two-dimensional electrons in a magnetic field, known as the Hofstadter butterfly.

The researchers performed the simulation on Google's chain of nine superconducting quantum bits (qubits), a breakthrough they say will enable future scientists to simulate and engineer materials with exotic electronic conduction properties.

"With chips similar to the one used in this experiment, we are interested to study problems at the core of condensed matter, statistical mechanics, and non-equilibrium dynamics," says Google's Pedram Roushan.
