Modular Architectures and Entanglement Schemes for Error-Corrected Distributed Quantum Computation
Siddhant Singh, Fenglei Gu, Sébastian de Bone +3
Connecting multiple smaller qubit modules by generating high-fidelity entangled states is a promising path for scaling quantum computing hardware. The performance of such a modular…
Hybrid Quantum Repeater Chains with Semiconductor Quantum Dots and Group-IV-Vacancy Color Centers in Diamond
Yannick Strocka, Fenglei Gu, Gregor Pieplow +2
We propose and analyze a hybrid quantum repeater architecture that combines two leading hardware platforms: quantum dots (QDs) as bright, deterministic sources of entangled photon…
The Group-IV-Vacancy Color Center in Diamond
Fenglei Gu
Group-IV vacancy (G4V, or XV, where X = Si, Ge, Sn, Pb) color centers constitute a novel and promising class of defects in diamonds. This chapter reviews and refines the theoretica…
Hybrid Quantum Repeaters with Ensemble-based Quantum Memories and Single-spin Photon Transducers
Fenglei Gu, Shankar G Menon, David Maier +5
Reliable quantum communication over hundreds of kilometers is a daunting yet necessary requirement for a quantum internet. To overcome photon loss, the deployment of quantum repeat…
