Spin-phonon interfaces in coupled nanomechanical cantilevers
Thomas Oeckinghaus, S. Ali Momenzadeh, Philipp Scheiger +5
Coupled micro- and nanomechanical oscillators are of fundamental and technical interest for emerging quantum technologies. Upon interfacing with long-lived solid-state spins, the c…
Tailoring spin defects in diamond
Felipe Fávaro de Oliveira, Denis Antonov, Ya Wang +6
Atomic-size spin defects in solids are unique quantum systems. Most applications require nanometer positioning accuracy, which is typically achieved by low energy ion implantation.…
Efficient creation of dipolar coupled nitrogen-vacancy spin qubits in diamond
Ingmar Jakobi, Seyed Ali Momenzadeh, Felipe Fávaro de Oliveira +6
Coherently coupled pairs or multimers of nitrogen-vacancy defect electron spins in diamond have many promising applications especially in quantum information processing (QIP) but a…
Nuclear Quantum-Assisted Magnetometer
Thomas Häberle, Thomas Oeckinghaus, Dominik Schmid-Lorch +5
Magnetic sensing and imaging instruments are important tools in biological and material sciences. There is an increasing demand for attaining higher sensitivity and spatial resolut…
Heralded Control of Mechanical motion by Single Spins
D. D. Bhaktavatsala Rao, S. Ali Momenzadeh, Jörg Wrachtrup
We propose a method to achieve high degree control of nanomechanical oscillators by coupling their mechanical motion to single spins. By manipulating the spin alone and measuring i…
Towards optimized surface -profiles of nitrogen-vacancy centers activated by helium irradiation in diamond
F. Favaro de Oliveira, S. A. Momenzadeh, D. Antonov +6
The negatively-charged nitrogen-vacancy (NV) center in diamond has been shown recently as an excellent sensor for external spins. Nevertheless, their optimum engineering in the nea…
Development of a high quality thin diamond membrane with embedded nitrogen-vacancy centers for hybrid spin-mechanical quantum systems
S. Ali Momenzadeh, Felipe Fávaro de Oliveira, Philipp Neumann +7
Hybrid quantum systems (HQSs) have attracted several research interests in the last years. In this Letter, we report on the design, fabrication, and characterization of a novel dia…
Effect of Low-Damage Inductively Coupled Plasma on Shallow NV Centers in Diamond
Felipe Fávaro de Oliveira, S. Ali Momenzadeh, Ya Wang +5
Near-surface nitrogen-vacancy ({NV}) centers in diamond have been successfully employed as atomic-sized magnetic field sensors for external spins over the last years. A key challen…
Nano-engineered Diamond Waveguide as a Robust Bright Platform for Nanomagnetometry Using Shallow Nitrogen Vacancy Centers
S. Ali Momenzadeh, Rainer J. Stöhr, Felipe Favaro de Oliveira +5
Photonic structures in diamond are key to most of its application in quantum technology. Here, we demonstrate tapered nano-waveguides structured directly onto the diamond substrate…
Coherent control of single spins in silicon carbide at room temperature
Matthias Widmann, Sang-Yun Lee, Torsten Rendler +15
Spins in solids are cornerstone elements of quantum spintronics. Leading contenders such as defects in diamond, or individual phosphorous dopants in silicon have shown spectacular…
