4 |01) + |10) Several of you were asking about the significance of the sign in states like (101) + (10)). This problem is designed to help Alica and Bob prepare two qubits in this state: 1 14) (01) + (10)) 12 1. Is y entangled? Why or why not? 2. What are the quantum numbers of in the coupled basis? 3. Alice measure o, and gets 1. Bob now measures Oz. What would he get and with what possibilities? 4. Alice measure o, and gets 1. Bob now measures oz. What would he get and with what possibilities? 5. Alice measure o, and gets 1. Bob now measures oz. What would he get and with what possibilities? Hint: Write y in the I+), |-1) basis 4 |01) + |10) Several of you were asking about the significance of the sign in states like (101) + (10)).
