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…
Optically Addressable Molecular Spins at 2D Surfaces
Xuankai Zhou, Yan-Tung Kong, Cheuk Kit Cheung +18
Optically addressable spins at material surfaces have represented a long-standing ambition in quantum sensing, providing atomic resolution and quantum-limited sensitivity. However,…
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…
Efficient Detection of Statistical RF Fields at High Magnetic Field with a Quantum Sensor
Rouven Maier, Cheng-I Ho, Hitoshi Sumiya +4
Nuclear magnetic resonance (NMR) spectroscopy is widely used in fields ranging from chemistry, material science to neuroscience. Nanoscale NMR spectroscopy using Nitrogen-vacancy (…
