Multicone Diamond Waveguides for Nanoscale Quantum Sensing
Tianqi Zhu, Jan Rhensius, Viraj Damle +4
The long-lived electronic spin of the nitrogen-vacancy (NV) center in diamond is a promising quantum sensor for detecting nanoscopic magnetic and electric fields in a variety of ex…
Fast scanning nitrogen-vacancy magnetometry by spectrum demodulation
P. Welter, B. A. Josteinsson, S. Josephy +4
We demonstrate a spectrum demodulation technique for greatly speeding up the data acquisition rate in scanning nitrogen-vacancy center magnetometry. Our method relies on a periodic…
Scanning nitrogen-vacancy center magnetometry in large in-plane magnetic fields
P. Welter, J. Rhensius, A. Morales +5
Scanning magnetometry with nitrogen-vacancy (NV) centers in diamond has emerged as a powerful microscopy for studying weak stray field patterns with nanometer resolution. Due to th…
The role of titanium in electromigrated tunnel junctions
Martin Frimmer, Gabriel Puebla-Hellmann, Andreas Wallraff +1
A standard route for fabrication of nanoscopic tunnel junctions is via electromigration of lithographically prepared gold nanowires. In the lithography process, a thin adhesion lay…
Electrolyte gate dependent high-frequency measurement of graphene field-effect transistor for sensing applications
W. Fu, M. El Abbassi, T. Hasler +8
We performed radiofrequency (RF) reflectometry measurements at 2.4 GHz on electrolyte-gated graphene field-effect transistors (GFETs) utilizing a tunable stub-matching circuit for…
Realization of Deterministic Quantum Teleportation with Solid State Qubits
L. Steffen, A. Fedorov, M. Oppliger +6
Transferring the state of an information carrier from a sender to a receiver is an essential primitive in both classical and quantum communication and information processing. In a…
Realization of GHz-frequency impedance matching circuits for nano-scale devices
G. Puebla-Hellmann, A. Wallraff
Integrating nano-scale objects, such as single molecules or carbon nanotubes, into impedance transformers and performing radio-frequency measurements allows for high time-resolutio…
