| contents | Ramsey spectroscopy, a fundamental tool in both basic science and practical applications, is inevitably subject to several detrimental effects. %
Here we propose a symmetry-protected destructive many-body interferometry (SPDMBI) for Ramsey spectroscopy, which successfully mitigates the spectral shift caused by interparticle interaction, noise, decoherence and experimental imperfection. %
Through matching the symmetry of the input states and the Hamiltonian, the SPDMBI-based Ramsey spectroscopy yields an antisymmetric spectrum, whose antisymmetric point exactly determines the resonance frequency. %
In such a Ramsey spectroscopy, the population difference under resonance is always zero, which is a result of destructive quantum interferometry. %
To demonstrate its versatility, we showcase successful applications of symmetry-protected Ramsey spectroscopy in measuring both time-independent and time-dependent signals. %
Our protocol can improve the performance of Ramsey spectroscopy, which offers a pathway for various high-precision quantum sensors. |
