Comparison of trapped-ion entangling gate mechanisms for mixed species
V. M. Schäfer, A. C. Hughes, O. Bazavan +4
Entangling gates are an essential capability of quantum computers. There are different methods for implementing two-qubit gates, with respective advantages and disadvantages. We in…

Benchmarking a high-fidelity mixed-species entangling gate
A. C. Hughes, V. M. Schäfer, K. Thirumalai +4
We implement a two-qubit logic gate between a hyperfine qubit and a Zeeman qubit. For this pair of ion species, the S--P optical trans…

High-rate, high-fidelity entanglement of qubits across an elementary quantum network
L J Stephenson, D P Nadlinger, B C Nichol +7
We demonstrate remote entanglement of trapped-ion qubits via a quantum-optical fiber link with fidelity and rate approaching those of local operations. Two Sr qubi…
