Abstract

We demonstrate a simplified method for generating an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher fidelity than previous demonstrations of dissipative entanglement generation, while eliminating the need for auxiliary ions. The entangled singlet state is generated in ∼7 ms with a fidelity of 0.949(4). The dominant source of infidelity is from photon scattering. We discuss this error source and strategies for its mitigation in detail.
