One qubit is in state alpha |0> + eta |1>, the other qubit in state |0>, and you apply a CNOT gate to the two qubits, what are the coefficients of the four possible states of the two qubits?
Added by Ashley T.
Step 1
The CNOT gate flips the second qubit (target qubit) if the first qubit (control qubit) is in state |1>. In this case, the first qubit is in the state \(\alpha |0> + \beta |1>\) and the second qubit is in the state |0>. Step 3: When the first qubit is in state Show more…
