Electrically Reconfigurable Silicon Carbide Nanophotonic Cavities on Thin-Film Lithium Niobate
San Lam Ng, Georgii Grechko, Vladislav Bushmakin +4
Interfacing integrated photonics with solid-state spin defects holds great promise for future quantum networks, but the scaling of spin-photon architectures is hindered by frequenc…
RF-free driving of nuclear spins with color centers in silicon carbide
Raphael Wörnle, Jonathan Körber, Timo Steidl +5
Color centers that enable nuclear-spin control without RF fields offer a powerful route towards simplified and scalable quantum devices. Such capabilities are especially valuable f…
Localization and coherent control of 25 nuclear spins in Silicon Carbide
Pierre Kuna, Erik Hesselmeier-Hüttmann, Phillip Schillinger +7
Optically addressable spin defects are excellent candidate platform for quantum sensing and quantum network. Nuclear spins coupled to color centers naturally enable long lived quan…
Waveguide-integrated colour centres in silicon carbide with broadband photonic crystal reflectors for efficient readout
Marcel Krumrein, Julian M. Bopp, Timo Steidl +5
Spin-active colour centres in 4H silicon carbide are promising candidates as building blocks for quantum information applications. To increase the photon count rate of the emitters…
Converting coherence into work with a fully quantum engine
MinSik Kwon, Tobias Denzler, Rouven Maier +4
Heat engines convert thermal energy into mechanical work. We here report the experimental realization of a fully quantum engine that converts quantum coherence into work. A single…
Readout of a solid state spin ensemble at the projection noise limit
Rouven Maier, Cheng-I Ho, Andrej Denisenko +4
Spin ensembles are central to quantum science, from frequency standards and fundamental physics searches to magnetic resonance spectroscopy and quantum sensing. Their performance i…
