Moving trapped-ion qubits in a microstructured array of radiofrequency traps offers a route
toward realizing scalable quantum processing nodes. Establishing such nodes, providing …

Trapped-ion systems are among the most promising hardware candidates for large scale
quantum computing and quantum simulation. In order to scale up such devices, it is …

Many remote-entanglement protocols rely on the generation and interference of photons
produced by nodes within a quantum network. Quantum networks based on heterogeneous …

Leggett-Garg inequality (LGI) is used to detect whether the macroscopic superposition state
exists. Classical systems obey the LGI, but quantum systems may violate it. In the multilevel …

We present the design and construction of a new experimental apparatus for the trapping of
single Ba+ ions in the center of curvature of an optical-quality hemispherical mirror. We …

The interfacing of quantum platforms via photonic links is a precursor for establishing
scalable quantum networks. The connection of different types of quantum memories for …

We present the design and experimental demonstration of an open-endcap radio frequency
trap to confine ion crystals in the radial-two dimensional (2D) structural phase. The central …

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 …

Trapped ions are excellent candidates for quantum nodes, as they possess many desirable
features of a network node including long lifetimes, on-site processing capability, and …

Practical implementation of quantum networks is likely to interface different types of quantum
systems. Photonically linked hybrid systems, combining unique properties of each …
