Charlee Stefanski and Constantin Gonciulea, co-authors of Building Quantum Software, are interviewed by Yuval Boger. Charlee, a software engineer, and Constantin, an expert in math and quantum computing, both from Wells Fargo, discuss their new book aimed at developers and readers with a basic background in math and programming, emphasizing a deeper understanding of quantum algorithms like Grover’s algorithm and the quantum Fourier transform. They also cover the importance of hybrid quantum-classical algorithms and the development of their own high-performance quantum simulator. The conversation touches on the current state of quantum software tools, the challenges of scaling quantum algorithms, and the potential business impact of quantum computing, particularly in optimization and finance, and much more.
