Advances in physical qubit quality and scalability are essential to achieve practical quantum computing. However, hardware progress alone is insufficient to reach utility-scale quantum systems. The co-design of quantum software will be critical for optimizing physical resources and enabling the seamless integration of quantum technologies into broader applications. In this talk, we will explore the critical role of the quantum software stack in overcoming bottlenecks in scaling quantum systems. We will place special emphasis on compilers. The first half of this talk documents the evolution of quantum software while providing an overview of the quantum compiler pipeline. The second half will highlight state-of-art software techniques for quantum error management and outline promising future directions for the quantum stack.
