Interplay between Hund's rule and Kondo effect in a quantum dot
Olfa Dani, Johannes C. Bayer, Timo Wagner +2
The interaction between localized spins on a quantum dot and free electrons in the reservoirs forms a many-particle entangled system giving rise to the Kondo effect. Here, we inves…
Real-Time Detection and Control of Correlated Charge Tunneling in a Quantum Dot
Johannes C. Bayer, Fredrik Brange, Adrian Schmidt +4
We experimentally demonstrate the real-time detection and control of correlated charge tunneling in a dynamically driven quantum dot. Specifically, we measure the joint distributio…
Spectral properties of stochastic resonance in quantum transport
Robert Hussein, Sigmund Kohler, Johannes C. Bayer +2
We investigate theoretically and experimentally stochastic resonance in a quantum dot coupled to electron source and drain via time-dependent tunnel barriers. A central finding is…
Controlled emission time statistics of a dynamic single-electron transistor
Fredrik Brange, Adrian Schmidt, Johannes C. Bayer +3
Quantum technologies involving qubit measurements based on electronic interferometers rely critically on accurate single-particle emission. However, achieving precisely timed opera…
Strong suppression of shot noise in a feedback-controlled single-electron transistor
T. Wagner, P. Strasberg, J. C. Bayer +3
Feedback control of quantum mechanical systems is rapidly attracting attention not only due to fundamental questions about quantum measurements but also because of its novel applic…
Partitioning of on-demand electron pairs
Niels Ubbelohde, Frank Hohls, Vyacheslavs Kashcheyevs +6
We demonstrate the high fidelity splitting of electron pairs emitted on demand from a dynamic quantum dot by an electronic beam splitter. The fidelity of pair splitting is inferred…
Induced Superconductivity in the Quantum Spin Hall Edge
Sean Hart, Hechen Ren, Timo Wagner +6
Topological insulators are a newly discovered phase of matter characterized by a gapped bulk surrounded by novel conducting boundary states. Since their theoretical discovery, thes…
