Illustration of the quantum physics concept known as “superposition.” In the ordinary classical world, a skateboarder could be in only one location or position at a time, such as the left side of the ramp (which could represent a data value of 0) or the right side (representing a 1). But if a skateboarder could behave like a quantum object (such as an atom), he or she could be in a “superposition” of 0 and 1, effectively existing in both places at the same time.
