The four bell states are(adsbygoogle = window.adsbygoogle || []).push({});

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?
