Advances in the control and manipulation of 133Ba+ Qubits

We present advances in trapped ion quantum computing by utilizing state mixing at non-zero magnetic fields to achieve "magic conditions," which result in a significant increase in qubit coherence time when exposed to high power lasers. Our study of the 133Ba+ trapped ion qubit highlights its exceptional qubit state preparation and measurement (SPAM) fidelity and its unique features, including optical and long-lived metastable qubit states. Our results demonstrate new capabilities for manipulation between qubit states and progress towards implementing single and two qubit gates, offering potential for practical applications in quantum computing.
