Exploiting the Benefits of Clean Ancilla Based Toffoli Gate Decomposition Across Architectures
AbstractElementary gate decomposition of larger Toffoli operations is often carried out using additional qubits (ancilla). The number of gates and the circuit depth vary in such transformation depending on the type of ancilla used (clean or dirty). The ...
