Can surface-transfer doping and UV irradiation during annealing improve shallow implanted Nitrogen-Vacancy centers in diamond?
N. J. Glaser, G. Braunbeck, O. Bienek +2
It has been reported that conversion yield and coherence time of ion-implanted NV centers improve if the Fermi level is raised or lowered during the annealing step following implan…
Decoherence mitigation by real-time noise acquisition
Georg Braunbeck, Maximilian Kaindl, Andreas Michael Waeber +1
We present a scheme to neutralize the dephasing effect induced by classical noise on a qubit. The scheme builds upon the key idea that this kind of noise can be recorded by a class…
A Planar Scanning Probe Microscope
Stefan Ernst, Dominik M. Irber, Andreas M. Waeber +2
Scanning probe microscopy (SPM) is traditionally based on very sharp tips, where the small size of the apex is critical for resolution. This paradigm is about to shift, since a nov…
Can ultraprecision polishing techniques improve the coherence times of nitrogen-vacancy centers in diamond?
G. Braunbeck, S. Mandal, M. Touge +2
We investigate the correlation between surface roughness and corresponding times of nearsurface nitrogen-vacancy centers (~7 nm/ 5 keV implantation energy) in diamond. For th…
Quantum Sensing of Weak Radio-Frequency Signals by Pulsed Mollow Absorption Spectroscopy
Timo Joas, Andreas M. Waeber, Georg Braunbeck +1
Quantum sensors, qubits sensitive to external fields, have become powerful detectors for various small acoustic and electromagnetic fields. A major key to their success have been d…
Efficient electrical spin readout of NV- centers in diamond
Florian M. Hrubesch, Georg Braunbeck, Martin Stutzmann +2
Using pulsed photoionization the coherent spin manipulation and echo formation of ensembles of NV- centers in diamond are detected electrically realizing contrasts of up to 17 %. T…
Broadband Electrically Detected Magnetic Resonance Using Adiabatic Pulses
F. M. Hrubesch, G. Braunbeck, A. Voss +2
We present a broadband microwave setup for electrically detected magnetic resonance (EDMR) based on microwave antennae with the ability to apply arbitrarily shaped pulses for the e…
