Schematic illustration of Hadamard operation on the computational basis of a two-qubit system using the W operator (Eq. (6)) on a single particle quantum walk on two-point position space. On the first qubit it is the Hadamard operation and on the second qubit Hadamard operation is realized using the \(\sigma _x\) and \({\mathbb {I}}\) operators.
