A Data-Centric Approach for Training Deep Neural Networks with Less Data
Mohammad Motamedi, Nikolay Sakharnykh, Tim Kaldewey
While the availability of large datasets is perceived to be a key requirement for training deep neural networks, it is possible to train such models with relatively little data. Ho…
Optical nanoscopy via quantum control
Timo Kaldewey, Andreas V. Kuhlmann, Sascha R. Valentin +3
We present a scheme for nanoscopic imaging of a quantum mechanical two-level system using an optical probe in the far-field. Existing super-resolution schemes require more than two…
Coherent and robust high-fidelity generation of a biexciton in a quantum dot by rapid adiabatic passage
Timo Kaldewey, Sebastian Lüker, Andreas V. Kuhlmann +6
A biexciton in a semiconductor quantum dot is a source of polarization-entangled photons with high potential for implementation in scalable systems. Several approaches for non-reso…
Demonstrating the decoupling regime of the electron-phonon interaction in a quantum dot using chirped optical excitation
Timo Kaldewey, Sebastian Lüker, Andreas V. Kuhlmann +7
Excitation of a semiconductor quantum dot with a chirped laser pulse allows excitons to be created by rapid adiabatic passage. In quantum dots this process can be greatly hindered…
Massively-Parallel Lossless Data Decompression
Evangelia Sitaridi, Rene Mueller, Tim Kaldewey +2
Today's exponentially increasing data volumes and the high cost of storage make compression essential for the Big Data industry. Although research has concentrated on efficient com…
All optical quantum control of a spin-quantum state and ultrafast transduction into an electric current
K. Müller, T. Kaldewey, R. Ripszam +6
The ability to control and exploit quantum coherence and entanglement drives research across many fields ranging from ultra-cold quantum gases to spin systems in condensed matter.…
High fidelity optical preparation and coherent Larmor precession of a single hole in an InGaAs quantum dot molecule
K. Müller, A. Bechtold, C. Ruppert +8
We employ ultrafast pump-probe spectroscopy with photocurrent readout to directly probe the dynamics of a single hole spin in a single, electrically tunable self-assembled quantum…
