Analogy

Imagine you are building a complex puzzle. The puzzle pieces represent the different components of a quantum program, and the picture on the puzzle represents the desired outcome. OSS toolkits are like a guidebook that provides step-by-step instructions on how to assemble the puzzle correctly. They also provide additional tools and resources to help you verify that the puzzle is assembled correctly. Without the guidebook, it would be challenging to know where each piece goes and how they fit together. Similarly, without OSS toolkits, implementing quantum programs would be much more challenging and time-consuming.
