In the noisy intermediate-scale quantum era (NISQ), we are likely to achieve practical quantum advantage using near-term programmable quantum hardware. We focus on the variational quantum algorithm paradigm and make progress in circuit structure design automation and circuit parameter optimization. In this talk, I will discuss how to design quantum circuit structures by various quantum architecture search methods and how to accelerate variational quantum algorithms training by novel optimization strategies. Besides, I will also introduce the high-performance quantum software framework for the NISQ era – TensorCircuit, which supports these research works by efficient numerical simulation and powerful quantum hardware connection. These works together pave the way to better understanding and investigating the power of NISQ devices.
