TITAN: A Fast and Distributed Large-Scale Trapped-Ion NISQ Computer
DescriptionTrapped-Ion (TI) technology offers potential breakthroughs for Noisy Intermediate Scale Quantum (NISQ) computing. TI qubits provide advantages like extended coherence times and high gate fidelity, making them appealing for large-scale quantum systems. Constructing such systems demands a distributed architecture connecting Quantum Charge Coupled Devices (QCCDs) via quantum matter-links and photonic switches. However, current distributed TI NISQ computers face hardware and system challenges. Entangling qubits across a photonic switch introduces significant latency, impacting performance, while existing compilers generate suboptimal mappings and schedules. In response, we introduce TITAN, a large-scale distributed TI NISQ computer. TITAN employs an innovative photonic interconnection design to reduce entanglement latency and an advanced partitioning and mapping algorithm to optimize quantum matter-link communications. Our evaluations show that TITAN significantly enhances quantum application performance and fidelity compared to existing systems.
