Pulse-Level Compilation of Measurement-Free Recovery in Transmon Circuits
A numerical study shows that a fixed, input-independent pulse sequence can be compiled for an interacting transmon circuit to enact a local recovery rule. In a simulated four-qubit repetition-code ring, this open-loop control slows the decay of encoded information without syndrome measurement or conditional feedback.

Experimental groups could demonstrate a measurement-free repetition-code recovery cycle on existing multi-qubit transmon devices without fast conditional feedback within the next two years.
The result is numerical but relies on pulse-level control already available on transmon platforms; if the compiled open-loop cycles can be calibrated on hardware and match simulated performance, the barrier to implementing measurement-free QEC is largely engineering rather than new physics.
