Multi-Qubit Superposition: The Mega-Qubit

Controlling randomness is, without doubt, an essential ingredient for quantum computing. But quantum computing offers an even more compelling case for reinventing computing. It gives us a way to deal with the entire solution space as a single unit. This may sound intimidating, but we’ll learn that to think about the entire solution space at once, we must focus on the characteristics a solution obeys rather than on the individual solutions themselves. So, before designing quantum algorithms that find a solution to a system of Boolean expressions, we need to first get comfortable with this shift in mindset.

For our next exercise, we’ll deal with two qubits and learn how to grapple with ...
