Webof SSS: one-axis twisting (OAT) and two-axis countertwisting (TACT) [1]. OAT SSS can be realized by the Hamiltonian H 1 ∝ J2 x and allow precise measurements to scale with 1/N 2/3, where N is the spin number of the system. TACT can be generated under the Hamiltonian H 2 ∝ J2 x − J2 y and causes Heisenberg limited noise reduction to scale ...
