- Abstract: Quantum Error Mitigation is essential for enhancing the reliability of quantum computing experiments. The adaptive KIK error mitigation method has demonstrated significant advantages, including resilience to noise parameter time-drift, applicability to non-Clifford gates, and guaranteed performance bounds. However, its reliance on global noise amplification introduces limitations, such as incompatibility with mid-circuit measurements and dynamic circuits, as well as small unaccounted errors due to higher-order Magnus noise terms. In this work, we propose a layer-based noise amplification approach that overcomes these challenges without incurring additional overhead or experimental complexity. Since the layered KIK framework is inherently compatible with mid-circuit measurements, it enables seamless integration with error correction codes. This synergy allows error correction to address dominant noise mechanisms while the layered KIK suppresses residual errors arising from leakage and correlated noise sources.

We microscopically model crosstalk errors from first principles and present a detailed study showing the importance of using a coherent vs incoherent error modelling and, moreover, discuss strategies to actively suppress this crosstalk at the gate level.
