Measuring Quantum Geometric Tensor of Non-Abelian System in Superconducting Circuits
文献摘要：
Topology played an important role in physics research during the last few decades.In particular,the quantum geometric tensor that provides local information about topological properties has attracted much attention.It will reveal interesting topological properties but have not been measured in non-Abelian systems.Here,we use a four-qubit quantum system in superconducting circuits to construct a degenerate Hamiltonian with parametric modulation.By manipulating the Hamiltonian with periodic drivings,we simulate the Bernevig-Hughes-Zhang model and obtain the quantum geometric tensor from interference oscillation.In addition,we reveal its topological feature by extracting the topological invariant,demonstrating an effective protocol for quantum simulation of a non-Abelian system.
