Google Patents US10755193B2 - Implementation of error mitigation for quantum computing machines Here, we believe that our method paves a new way for adaptive construction of ansatz circuits for variational quantum algorithms.US10755193B2 - Implementation of error mitigation for quantum computing machines Our numerical experiments show that a reduced entangler pool with a small portion of the original entangler pool can achieve same numerical accuracy. We corroborate our method more » numerically on small molecules. The density matrix renormalization group method is employed for classical precomputation in this work. Our method uses mutual information between the qubits in classically approximated ground state to rank and screen the entanglers. In this work, we propose a way to construct entangler pools with reduced size by leveraging classical algorithms. Those algorithms aim to build up optimal circuits for a certain problem and ansatz circuits are adaptively constructed by selecting and adding entanglers from a predefined pool. Adaptive construction of ansatz circuits offers a promising route towards applicable variational quantum eigensolvers on near-term quantum hardware.
