Analysis of Parameterized Quantum Circuits: On the Connection Between Expressibility and Types of Quantum Gates

Expressibility is a crucial factor of a parameterized quantum circuit (PQC). In the context of variational-quantum-algorithm-based quantum machine learning (QML), a QML model composed of a highly expressible PQC and a sufficient number of qubits is theoretically capable of approximating any arbitrar...
