Noisy intermediate scale quantum (NISQ) algorithms arise in the recent years as they have the potential to be implemented on the near-term quantum devices to demonstrate a certain level of quantum advantage. Among many proposed algorithms, the classical-quantum hybrid algorithms stand out to be promising candidates, in particular the variational quantum eigensolver (VQE). This talk covers two applications of VQE, one is to solve linear algebra problems and the other is to search for the encoding circuits of quantum error correction codes. In the first part, I will show the solutions of linear systems of equations and matrix-vector multiplications can be translated as the ground states of the constructed Hamiltonians. The cost and effectiveness of the algorithm are evaluated through numerical simulations, and the algorithm is also implemented on the IBMQ device. In the second part, I will show a quantum compiler that can find efficient encoders for logical states of an error correction code for general quantum hardware.  The discovered circuits can be further augmented with error detection.
