Towards cavity enhanced fast mid-circuit measurement in ytterbium atom arrays

We are developing a new platform for quantum science that integrates cavity-based fast, non-destructive, and local mid-circuit measurement with an optical tweezer array of Ytterbium atoms. We are addressing a primary limitation of the well-established neutral atom array architecture, namely slow measurement. Leveraging an optical cavity is expected to improve measurement times by approximately three orders-of-magnitude compared to standard fluorescence detection, and two orders of magnitude compared to schemes limited by atom transport, with direct implications on available circuit depth. We will implement programmable and local mid-circuit measurements by spectrally tuning the cavity-coupled transition with tweezer depth. To address the initial scalability limitation of a 1d cavity mode we will ultimately engineer a degenerate multi-modal cavity to enable transverse control over the cavity mode. This architecture is compatible with Rydberg-based entangling operations and native multi-qubit collective measurements which will enable applications including quantum error correction for quantum computation, studies of entanglement transitions in interacting spin models, and quantum interactive matter.
