Realizing primitive qubit operations for omg processing in ¹³³Ba⁺

In large-scale, fault-tolerant quantum computing, a large number of physical qubits are needed. For trapped atom and ion processors, two species of atoms are often used: one for information processing and another for cooling. This dual-species approach for ions helps control heating during complex algorithms and transport but leads to complications due to mass differences between the species. The 'omg protocol' offers a solution using a single atomic species and different qubit types (optical, metastable, and ground; omg). This approach assigns different tasks to various parts of the atomic Hilbert space, more-efficiently utilizing the resources present and avoiding mass mismatch problems. Barium-133, a synthetic, radioactive isotope of Barium, is well-suited for this protocol. We report on progress toward implementation of gates driven by stimulated-Raman transitions as well as coherent g→ m qubit transfer in ¹³³Ba⁺.
