Parameterized quantum circuits (PQC) comprising local parameterized single-qubit and two-qubit unitary gates have emerged as versatile tools for enhancing the performance of quantum processors through classical optimization techniques. Meanwhile, solid-state embedded defect qubit platforms hold promise as quantum processors for applications ranging from quantum simulations to quantum communications and sensing. In this talk, we present a theoretical framework for constructing an efficient PQC structure tailored to solid-state defect qubit systems, particularly for quantum state tomography (QST) tasks. We introduce a novel PQC optimization scheme aimed at generating a set of POVM operators optimized for high-fidelity QST under the constraint of coarse-grained measurements of multi-qubit systems. This optimization methodology enables the design of robust schemes to operate quantum processors under various error conditions. * Zoom 회의실 별도 공지
