Quantum search on noisy intermediate-scale quantum devices

Abstract: Quantum computers have the computational power which is superior to classical computers. More and more quantum computers are open to researchers, such as IBMQ, IonQ and Honeywell Quantum Solutions. We have entered the noisy intermediate-scale quantum (NISQ) era. In this talk, I will show how to implement quantum search algorithms on NISQ devices. Quantum search algorithms (Grover’s algorithm) find the target item for the unstructured search problem. It provides a quadratic speedup compared to classical algorithms. I will present our latest results from IBMQ, IonQ and Honeywell quantum devices. I will also talk about how to improve the performance of quantum search algorithms on NISQ devices. The talk is based on arXiv:2102.01783, arXiv:2202.00122.
