Quantum Algorithm Grand Challenge 2024: How to Make Better Use of NISQ Devices to Enable Algorithms for Practical Applications

As quantum computing technology advances and qubit capacities continue to increase, it becomes crucial to leverage NISQ devices effectively and to develop NISQ algorithms that facilitate practical applications. Quantum chemistry is among the most promising fields for quantum computing, with numerous NISQ algorithms already devised for this purpose. When considering the application of these algorithms, key questions arise: Among the many NISQ algorithms published, which ones are considered state-of-the-art? How do we determine if modifications to an algorithm improve its performance? And which algorithm best suits a particular company’s needs? To address these questions, we initiated the QAGC last year. This year’s QAGC, running from February to the end of June, challenges participants to tackle problems using a 28-qubit system. During the workshop, we will begin by outlining the motivations behind the QAGC and the methods used to assess algorithm performance in a 90-minute session, which will also cover the evolution of the QAGC since its inception. Subsequently, we will feature presentations from the top three winning teams, with each team leading a 30-minute discussion on their innovative algorithms. The workshop will conclude with a celebration of the winners, a dialogue on future directions for the QAGC, and final remarks. Throughout the event, we aim to foster a dynamic dialogue with the audience about the criteria for evaluating applications and the performance of underlying algorithms.
