Question: Using (one-qubit) Hadamard gate and (two qubit) CNOT gate, construct a (two-qubit) gate which has a Bell state xy> as the output for the input

Using (one-qubit) Hadamard gate and (two qubit) CNOT gate, construct a (two-qubit) gate which has a Bell state xy> as the output for the input xy=xy>. Recall the Bell states are 4 states defined by xy>:=21(0y>+(1)x1y>)x,y{0,1} Verify that all the Bell states form an orthogonal basis of C2C2 and are entangled. H=21(1111)CNOT=1000010000010010
