The Challenge

The HPC center was running quantum simulations on classical infrastructure but had no reproducible way to validate that their digital twin matched actual QPU behavior. Auditors required cryptographic proof of each simulation run, and manual logging was error-prone and time-consuming.

The Solution

QCOS orchestrated circuit execution across both classical simulators and partner QPUs, automatically generating evidence bundles for each run. The Evidence Ledger provided immutable audit trails, while ACOS-certified backends ensured consistent benchmarking.

QCOS eliminated our manual logging burden. Every simulation now has a cryptographic audit trail that satisfies our funding body requirements.
