Implementation of the Fredkin gate with a three-qubit mixed-spin Heisenberg model

We show that a local unitary (LU) equivalent Fredkin gate can be obtained from the free evolution of three mixed-spin qubits by virtue of numerical simulation with only one step. The spin-1 qubit acts as the control qubit, and two spin-1/2 qubits, which interact with the spin-1 qubit via the first n...
