Low noise quantum frequency conversion of photons from a trapped barium ion to the telecom O-band

Uday Saha, James D. Siverns, John Hannegan +2

Trapped ions are one of the leading candidates for scalable and long-distance quantum networks because of their long qubit coherence time, high fidelity single- and two-qubit gates…

Entanglement between a trapped ion qubit and a 780-nm photon via quantum frequency conversion

John Hannegan, James D. Siverns, Qudsia Quraishi

Future quantum networks will require the ability to produce matter-photon entanglement at photon frequencies not naturally emitted from the matter qubit. This allows for a hybrid n…

Routing Single Photons from a Trapped Ion Using a Photonic Integrated Circuit

Uday Saha, James D. Siverns, John Hannegan +4

Trapped ions are promising candidates for nodes of a scalable quantum network due to their long-lived qubit coherence times and high-fidelity single and two-qubit gates. Future qua…

C-band single photons from a trapped ion via two-stage frequency conversion

John Hannegan, Uday Saha, James D. Siverns +3

Fiber-based quantum networks require photons at telecommunications wavelengths to interconnect qubits separated by long distances. Trapped ions are leading candidates for quantum n…

Quantum interference between photons from an atomic ensemble and a remote atomic ion

A. N. Craddock, J. Hannegan, D. P. Ornelas-Huerta +6

Advances in the distribution of quantum information will likely require entanglement shared across a hybrid quantum network. Many entanglement protocols require the generation of i…
