Toric code (IMAGE)
Caption
In collaboration with the Google Quantum AI team scientists from the Technical University of Munich (TUM) and the University of Nottingham used a quantum processor to simulate the ground state of a so-called toric code Hamiltonian – an archetypical model system in modern condensed matter physics, which was originally proposed in the context of quantum error correction. The image shows the experimentally measured parity values for a 31-qubit lattice in the toric code ground state. The qubits (“×”) are placed on the links of a square lattice. The parity expectation values of the star- and plaquettes operators are shown as blue and purple tiles, respectively. The average fidelity of 0.92 ±0.06 shows that the ground state has been prepared with high accuracy.
