DOI: 10.1103/physrevlett.129.063603
Abstract: We describe a simple protocol for the single-step generation of N-body entangling interactions between trapped atomic ion qubits. We show that qubit state-dependent squeezing operations and displacement forces on the collective atomic motion can generate… read more here.
