A three-qubit system is in the state =( 20 2 +i )000+ 2 1 001+ 10 1 011+ 2 i 111 146 QUANTUM MEASUREMENT THEORY (A) What is the probability that the system is found in the state 011 if all three qubits are measured? (B) What is the probability that a measurement on the second qubit only gives 1? What is the postmeasurement state of the system? Show that the postmeasurement state is normalized
