Enhancing the Robustness of Dynamical Decoupling Sequences with Correlated Random Phases
We show that the addition of correlated phases to the recently developed method of randomized dynamical decoupling pulse sequences can improve its performance in quantum sensing. In particular, by correlating the relative phases of basic pulse units in dynamical decoupling sequences, we are able to...

| description | We show that the addition of correlated phases to the recently developed method of randomized dynamical decoupling pulse sequences can improve its performance in quantum sensing. In particular, by correlating the relative phases of basic pulse units in dynamical decoupling sequences, we are able to improve the suppression of the signal distortion due to <inline-formula> <math display="inline"> <semantics> <mi>π</mi> </semantics> </math> </inline-formula> pulse imperfections and spurious responses due to finite-width <inline-formula> <math display="inline"> <semantics> <mi>π</mi> </semantics> </math> </inline-formula> pulses. This enhances the selectivity of quantum sensors such as those based on NV centers in diamond. |
