Students rely on three distinct cognitive resources when reasoning about the CNOT gate, which can combine productively or lead to errors when handling superposition and entanglement.
2, Question 1 provides four 2-qubit quantum states and asks students which states (if any) would be left unchanged after the application of the CNOT gate

Can a CNOT Gate Affect the Control Qubit? Student Resources for Understanding CNOT and Entanglement
Students rely on three distinct cognitive resources when reasoning about the CNOT gate, which can combine productively or lead to errors when handling superposition and entanglement.
