(author), Sammak, A. (author), Veldhorst, M. (author), Scappucci, G. (author)The co-integration of spin, superconducting, and topological systems is emerging as an exciting pathway for scalable and high-fidelity quantum information technology. High-mobility planar germanium is a front-runner semiconductor for building quantum processors with spin-qubits, but progress with hybrid superconductor-semiconductor devices is...article 2023

Ruf, M. (author), IJspeert, M. (author), van Dam, S. (author), de Jong, N. (author), van den Berg, J.H. (author), Evers, G. (author), Hanson, R. (author)Diamond membrane devices containing optically coherent nitrogen-vacancy (NV) centers are key to enable novel cryogenic experiments such as optical ground-state cooling of hybrid spin-mechanical systems and efficient entanglement distribution in quantum networks. Here, we report on the fabrication of a (3.4 ± 0.2) μm thin, smooth (surface...article 2019

Tchebotareva, A. (author), Hermans, S.L.N. (author), Humphreys, P.C. (author), Voigt, D. (author), Harmsma, P.J. (author), Cheng, L.K. (author), Verlaan, A.L. (author), Dijkhuizen, N. (author), de Jong, W. (author), Dréau, A. (author), Hanson, R. (author)We report on the realization and verification of quantum entanglement between a nitrogen-vacancy electron spin qubit and a telecom-band photonic qubit. First we generate entanglement between the spin qubit and a 637 nm photonic time-bin qubit, followed by photonic quantum frequency conversion that transfers the entanglement to a 1588 nm photon....article 2019

Dréau, A. (author), Tcheborateva, A. (author), El Mahdaoui, A. (author), Bonato, C. (author), Hanson, R. (author)We report on the conversion to telecommunication wavelengths of single photons emitted by nitrogen-vacancy (NV) defect in diamond. By means of different frequency generation, we convert spin-selective photon at 637 nm, associated with the coherent NV zero-photon line, to the target wavelength of 1588 nm in the L-telecommunication band. The...article 2018
