Abstract
Distributed quantum computing (DQC) enables scalable quantum computation by connecting smaller processors. Two main approaches, entanglement-assisted LOCC and circuit knitting, offer complementary advantages: the former achieves deterministic nonlocal operations but requires substantial entanglement, while the latter avoids entanglement at the cost of large sampling overhead. In this talk, I introduce entanglement-assisted circuit knitting, a hybrid framework that incorporates limited entanglement into circuit knitting. Using a resource-assisted quasi-probability decomposition, we characterize the trade-off between sampling overhead and entanglement cost, deriving optimal protocols for special classes of unitaries and bounds for general cases. We further extend the framework to a black-box setting, enhancing flexibility for practical implementations. This approach provides a tunable balance between quantum and classical resources for efficient DQC.
