Protecting Heisenberg scaling in quantum metrology via engineered dressed states
A preprint posted to arXiv quant-ph on 24 August 2026 presents a scheme for protecting Heisenberg scaling in quantum metrology using engineered dressed states. The work targets decoherence, which typically erodes quantum-enhanced measurement precision.

The dressed-state protection scheme could enable existing quantum sensors, such as trapped-ion or NV-center platforms, to maintain Heisenberg scaling in noisy environments over the next two years.
Engineered dressed states have already been demonstrated for decoherence protection in several platforms, so applying them to metrology requires incremental adaptation rather than new hardware. If the theoretical protection holds experimentally, near-term sensors could operate closer to their fundamental precision limits.
