Fault-tolerant quantum computing changes what quantum software needs to do. 💫 Classiq has introduced the Fault Tolerance Engine, extending our platform from logical quantum program design all the way to fault-tolerant execution planning. The engine translates an optimized logical program into an architecture-aware implementation: laying out protected qubits, routing their interactions, scheduling operations, accounting for quantum error correction, and costly resources such as T gates and magic states. From the resulting execution plan, users can evaluate physical qubit requirements, error-correction cycles, code distance, runtime, accumulated error, and more. The goal is to answer a much more practical question: What will it actually take to run this application reliably on a fault-tolerant quantum computer? 📷
