# Two qubits entanglement in different basis - quantum circuit

I am trying to build a circuit that can detect which of the 4 entangled states i am in. The states are \begin{align} |0+\rangle &+ |1-\rangle\\ |0+\rangle &- |1-\rangle\\ |1+\rangle &+ |0-\rangle\\ |1+\rangle &- |0-\rangle \end{align}

What i am confused is both qubits are in different basis and how can i get information about the other qubit which is in a different basis? Won't there be loss of information if we tried using different basis? And also, is such a circuit possible to implement? How do i implement it?

First we apply a Hadamard on the second Qubit which takes $$|+ \rangle \rightarrow |0 \rangle$$ and $$|- \rangle \rightarrow |1 \rangle$$. Now the states have been transformed to:
$$\frac{1}{\sqrt2}(| 00 \rangle + |11 \rangle)$$ $$\frac{1}{\sqrt2}(| 00 \rangle - |11 \rangle)$$ $$\frac{1}{\sqrt2}(| 10 \rangle + |01 \rangle)$$ $$\frac{1}{\sqrt2}(| 10 \rangle - |01 \rangle)$$
And so now we are done. Given that our input the the circuit above are Bell States(which we just ensured is the case) we will measure the proper and $$x$$ and $$y$$ every time. It should be noted that the order in which the states were provided in the question are not the conventional ordering for the Bell States and so the measurements of $$x$$ and $$y$$ would have to be mapped to whatever ordering we are interested in.
