  "abstract": "We propose a scheme for preparing spin-squeezed states in an ensemble of $N$ spin-$1/2$ particles based on Grover's algorithm. With only a few oracles, the scheme can exactly prepare superpositions of a few neighboring Dicke states with the Wineland squeezing parameter scaling as $N^{-1}$. The scheme requires only global rotations and Dicke-selective phase shifts, thus avoiding the need to engineer a dedicated many-body Hamiltonian for the squeezing dynamics. We further discuss the feasibility of realizing the scheme in cavity QED systems, with the phase-matched Grover iterations realized by single-photon reflection from a dispersively coupled cavity. Full-sequence scattering calculations accounting for finite photon bandwidth and loss show that appreciable spin squeezing can be achieved with high fidelity for suitable system parameters.",
