The authors propose the use of ultrafast laser pulses to rapidly transfer quantum information between noisy network qubits and stable memory qubits in trapped-ion quantum networks. The authors demonstrate that high-fidelity and high-speed quantum logic operations are achievable between a broad range of mixed-species ion pairs, which allows multiple specialized qubits to be employed in quantum networks of trapped-ion processors.
