Optimal quantum control of multi-mode couplings between trapped ion qubits for scalable entanglement

T. Choi, S. Debnath, T. A. Manning +4

We demonstrate high fidelity entangling quantum gates within a chain of five trapped ion qubits by optimally shaping optical fields that couple to multiple collective modes of moti…

A circuit analysis of an in situ tunable radio-frequency quantum point contact

Thomas Müller, Theodore Choi, Sarah Hellmüller +3

A detailed analysis of the tunability of a radio-frequency quantum point contact setup using a C-LCR circuit is presented. We calculate how the series capacitance influences resona…

Counting statistics of hole transfer in a p-type GaAs quantum dot with dense excitation spectrum

Y. Komijani, T. Choi, F. Nichele +4

Low-temperature transport experiments on a p-type GaAs quantum dot capacitively coupled to a quantum point contact are presented. The time-averaged as well as time-resolved detecti…

Counting statistics in an InAs nanowire quantum dot with a vertically coupled charge detector

Theodore Choi, Thomas Ihn, Silke Schön +1

A gate-defined quantum dot in an InAs nanowire is fabricated on top of a quantum point contact realized in a two-dimensional electron gas. The strong coupling between these two qua…

Coherent Electron-Phonon Coupling in Tailored Quantum Systems

P. Roulleau, S. Baer, T. Choi +6

The coupling between a two-level system and its environment leads to decoherence. Within the context of coherent manipulation of electronic or quasiparticle states in nanostructure…

Highly Tunable Hybrid Quantum Dots with Charge Detection

C. Rössler, B. Küng, S. Dröscher +4

In order to employ solid state quantum dots as qubits, both a high degree of control over the confinement potential as well as sensitive charge detection are essential. We demonstr…
