Compilation-informed probabilistic logical-error cancellation
Researchers present a method that uses compilation information to inform probabilistic logical-error cancellation, aiming to improve reliability before fault-tolerant quantum error correction becomes scalable. The paper is framed against the challenge of reaching practical quantum advantage given current hardware error rates and the time needed to overcome QEC scalability issues.

This could allow near-term quantum processors to run deeper logical circuits than previously feasible by reducing the sampling overhead of probabilistic error cancellation through compiler-guided optimizations.
Existing probabilistic error cancellation already works on physical qubits, and compilation data is readily available; if the method can be integrated into existing transpilation pipelines, the next two years could see improved logical error rates without full fault tolerance.
