Explanation: The constructed 2D array should contain 2 rows and 2 columns. The first group of n=2 elements in original, [1,2], becomes the first row in the constructed 2D array. The second group of n=2 elements in original, [3,4], becomes the second row in the constructed 2D array...
The circuit for the transfer is shown in Fig. 2c, and it is redrawn in Fig. 2d because the second and third CNOTs in Fig. 2c are commutable. Qubits bmZ and bcZ are initialized to |0> and |+>, respectively; they are measured after the three CNOT operations; the transfer process...
