This work demonstrates a Heisenberg-limited metrology protocol via Floquet-engineered two-axis twisting and turning dynamics. Furthermore, the approach allows for efficient interaction-based readout without inverting the nonlinear interaction, thereby enhancing the robustness against detection noise.

The polynomial Heisenberg algebras (PHA) are deformations of the Heisenberg- Weyl algebra characterizing the underlying symmetry of the supersymmetric partners of the Harmonic oscillator. When looking for the simplest system ruled by PHA, however, we end up with the harmonic oscillator. In this paper we are going to realize the first-order PHA through the harmonic oscillator. The associated coherent states will be also constructed, which turn out to be the well known even and odd coherent states.
