Suppose you have $100$ qubits, and you do the following:

Zeroize them.

Apply Hadamards to the first $50.$

XOR the first $50$ into the second $50($pairwise$,$ using CNOT$).$

How many different values is it possible to read if you read all $100$ qubits?

Suppose you instead read the first $50$ qubits. How many possible values are superposed on the second set of $50$ qubits?
