Suppose we have two qubits in the state α|00⟩+β|11⟩. (a) If we measure the first qubit in the sign basis, what is the probability of seeing a +? (b) What is the resulting state of the second qubit in that case? Use a and b to denote α and β re...

A two-qubit system was originally in the state 34|00⟩−5√4|01⟩+14|10⟩−14|11⟩, and then we measured the first qubit to be 0. Now, if we measure the second qubit in the standard basis, what is the probability that the outcome is 0?
