Multi-qubit Rydberg blockade implementation of a NOT gate. Each control atom is sequentially excited from to in k π-pulses. Next, the target atom qubit states are swapped as in Figure 3(b), via the Rydberg state (conditioned on no control atom populating the state ). The control atoms are then returned to their original state in reverse order. The trace distance between the process matrix using this implementation for and the ideal Toffoli gate is shown as the lower curve in Figure 4.
