Mid-circuit measurement and reset using omg architecture in trapped-ion quantum computing systems

The omg quantum computer architecture encodes multiple types of qubits in a single atomic species, allowing dissipative qubit processes without crosstalk. We exploit omg for in-place mid-circuit measurement and reset (MCMR) operations on a full-scale trapped ion quantum computing system. We implement two different forms of omg by performing the dissipative functions on both the S_1/2 hyperfine qubit and the D_3/2 optical qubit in ¹⁷¹Yb ions, while discussing the constraints imposed by integration with a system engineered for high-fidelity gate operations.

Compared to the shuttling based techniques for MCMR, the omg architecture enables faster operation by eliminating the shuttling time and reducing the need for sympathetic cooling.
