I have created 10 qubits, where I have set 2 in superposition by applying Hadamard gate to each of the 2 qubits. So the 2 qubits state can be $|00\rangle$, $|01\rangle$, $|10\rangle$, $|11\rangle$. I need to assign values based on the values present in 2 superpositioned qubits. For eg, if the 2 qubits are in $|00\rangle$ I need to set the other qubits as $|00011110\rangle$, if the 2 qubits are in $|01\rangle$ states, I need to set the other qubits as $|10101010\rangle$ and if the 2 qubits are in $|11\rangle$ I need to set the other qubits as $|11110000\rangle$. So in the broad sense after applying H gate to 2 qubits when they have totally 4 states for each state I need to assign qubits other values. I saw I can apply the Toffoli gate if the state is |11⟩. However, if the state is $|01\rangle$ or $|00\rangle$ then what is the way?

Hi. Welcome to Quantum Computing SE! It is preferable that you use MathJax to typeset your posts. Review How to write a good question?. I've [edit]ed it on your behalf this time.
