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…

Probing Qubit Memory Errors at the Part-per-Million Level
M. A. Sepiol, A. C. Hughes, J. E. Tarlton +7
Robust qubit memory is essential for quantum computing, both for near-term devices operating without error correction, and for the long-term goal of a fault-tolerant processor. We…
