The four bell states are
1: (|00>+|11>)(2)^-0.5
2: (|00>-|11>)(2)^-0.5
3: (|01>+|10>)(2)^-0.5
4: (|01>-|10>)(2)^-0.5
I'm looking at super dense coding and the way i thought of it at first was that if a measurement of the first qubit was made then if we consider the first bell state (1) if 0 is the value obtained then the system if forced into the state |00> so that measurement of the second qubit yields 0 with certainty..
Now take (2) if we measure the first qubit and we get 0 then apparently measurement of the 2nd qubit yields 1 with certainty.. So my way of thinking isn't correct lol
Can someone clarify?
