Researchers are revisiting fundamental ideas in computing history, including Alan Turing's theories from the 1930s on digital computers' potential capabilities.
Turing explored computation and modeling natural processes, noting in the 1950s that simulating quantum phenomena would require vast resources, even with future advances.
These were the initial seeds of what we now call quantum computing.
The challenge of simulating quantum systems with classical computers led to explorations of creating computers based on quantum mechanics, initially confined to theoretical physics and abstract mathematics.
