Hybrid quantum program failures frequently occur silently, yet existing debugging tools provide limited support for detecting and repairing them. These faults dominate the failures reported by domain experts, yet existing tools evaluate on public data that under-represents this failure mode. Our key insight is that fau...

AOSpec: Action and Observation Co-Speculation for Low-Latency Agent Serving

This work presents AOSpec, a lossless framework that co-speculates actions and observations across the full agent-environment loop, and outperforms every practical baseline, reducing mean end-to-end latency by 11.8-32.5% and p99 latency by up to 42.8%.
