【题目】Error-resilient quantum sensing

【摘要】Quantum sensing exploits the extreme sensitivity of quantum systems to perturbations to acquire minute signals from the environment. To detect signals accurately and reliably, it is crucial to address errors in control fields and decoherence noise from the environment. In this talk, we present robust quantum sensing protocols. In particular, we show that the use of the quantum adiabatic jumping protocol allows for reliable quantum sensing of dynamical signals. This approach can simultaneously (1) suppress the effect of errors in the control fields, (2) prolong quantum coherence times for higher sensitivity, and (3) remove spurious responses and higher harmonics that are commonly encountered in dynamical decoupling (DD) sensing sequences. This provides a new route for developing sensing protocols beyond DD-based techniques.
