Engineering magnetically insensitive qubits in metastable electronic D-states of trapped ions
Ksenia Sosnova, Martin Lichtman, Allison Carter +2
Ion trap quantum computers often store qubits on field-sensitive S_1/2 ground state Zeeman levels of the valence electron, such as in 40Ca+, 88Sr+, and 138Ba+ atomic systems. We ex…

Fast photon-mediated entanglement of continuously-cooled trapped ions for quantum networking
Jameson O'Reilly, George Toh, Isabella Goetting +8
We entangle two co-trapped atomic barium ion qubits by collecting single visible photons from each ion through in-vacuo 0.8 NA objectives, interfering them through an integrated fi…

Ion Trap with In-Vacuum High Numerical Aperture Imaging for a Dual-Species Modular Quantum Computer
Allison L. Carter, Jameson O'Reilly, George Toh +4
Photonic interconnects between quantum systems will play a central role in both scalable quantum computing and quantum networking. Entanglement of remote qubits via photons has bee…
