No, the notion that a quantum d-wave computer is controlling everything in the world or that it is the operating system for a system grid is not accurate or supported by current scientific understanding.
Quantum computers, including those developed by D-Wave Systems, are a type of advanced computing technology that utilize the principles of quantum mechanics to perform certain types of calculations more efficiently than classical computers. However, quantum computers are still in the early stages of development and are not yet capable of replacing classical computers or controlling everything in the world.
The notion of a "system grid" controlling everything is also not a widely recognized concept in science. It is important to distinguish between fictional portrayals of advanced technologies, such as those often depicted in movies or works of science fiction, and the current state of scientific knowledge and technological capabilities.
In reality, our world operates based on a complex interplay of various natural forces, physical laws, biological processes, and human actions. Advanced computing technologies, including quantum computers, play a role in certain scientific and technological domains, but they are not all-encompassing controllers of the world.
