 Although quantum systems may sometimes be in a pure superposition of measurable states, we never observe our measurement devices to be in such states when they interact with quantum systems. On the contrary, our measurement devices always seem to display definite values. Why? Hepp (1972) proposed to explain this by modeling the measurement process using a quantum supertask. This example was popularized by Bell (1987, §6) and proposed as a solution to the measurement problem by Wan (1980) and Bub (1988).
