For MICRO 2025: The 58th IEEE/ACM International Symposium on Microarchitecture (MICRO 2025) was held on October 18-22, 2025 in Seoul, Korea. MICRO is a premier forum for presenting, discussing, and debating innovative microarchitecture ideas and techniques for advanced computing and communication systems.

For the paper MUSS-TI: Multi-level Shuttle Scheduling for Large-Scale Entanglement Module Linked Trapped-Ion: Trapped-ion computing is a promising route toward scalable and high-fidelity quantum systems. In modular trapped-ion architectures, multiple Quantum Charge-Coupled Device (QCCD) units can be connected through entanglement modules, but efficient compilation remains challenging because excessive ion shuttling introduces major overhead. We propose MUSS-TI, a scalable compiler for Entanglement Module Linked QCCD (EML-QCCD) systems. MUSS-TI introduces a multi-level scheduling strategy inspired by multi-level memory scheduling in classical computing, and it is aware of the distinct roles of different zones in the architecture to minimize shuttle operations. Our evaluation shows that MUSS-TI reduces shuttle operations by 41.74% for applications with 30-32 qubits, and by an average of 73.38% and 59.82% for applications with 117-128 qubits and 256-299 qubits, respectively.
