QC Design Publishes Unified “Plaquette” Framework to Automate Hardware-Aware Fault-Tolerant Simulation

Quantum design-automation developer QC Design has published a comprehensive theoretical framework and software specification detailing its flagship architecture-simulation platform, Plaquette. Released in an academic paper on arXiv (“Plaquette: A hardware-aware design platform for fault-tolerant quantum computers“), the disclosure marks a shift from idealized, Clifford-only error approximations toward continuous, physics-rooted structural simulation of real-world physical qubit imperfections. The company’s architecture addresses a persistent blind spot in quantum error correction (QEC): standard stabilizer simulators traditionally assume uniformly distributed, stochastic Pauli noise, an assumption that the paper demonstrates can underestimate logical error rates by more than an order of magnitude.
