Expressibility and trainability of a two-dimensional pairwise quantum-circuit ansatz

Shuai Zhang, Wei Liu, Ji-Chong Yang

The paper introduces a native two-dimensional pairwise parameterized quantum circuit ansatz and compares its expressibility and trainability to common one-dimensional ansatze on a…
