given an EPR pair, how do I calculate expectation values?
given A and B share EPR pairs
Here A is the 1st-qubit while B is the 2nd-qubit. And, both A and B are free to measure their own qubit with the following measurement settings
A measures with or
B measures with or
How do I calculate the expectation value, if A measures in
basis and b measures in basis?
I know that expectation value is in this format , I would like to know what should be in place of and how to find it ?
