In-situ control of hole-spin driving mechanisms
Simon Geyer, Rafael S. Eggli, Carlos dos Santos +6
Hole-spin qubits enable fast, all-electrical spin manipulation through electric-dipole spin resonance (EDSR), arising from two microscopic mechanisms rooted in their intrinsically…
All-electrical operation of a spin qubit coupled to a high-Q resonator
Rafael S. Eggli, Taras Patlatiuk, Eoin G. Kelly +5
Building a practical quantum processor involves integrating millions of physical qubits along with the necessary components for individual qubit manipulation and readout. Arrays of…
Exchange energy of the ferromagnetic electronic ground-state in a monolayer semiconductor
Nadine Leisgang, Dmitry Miserev, Hinrich Mattiat +6
Mobile electrons in the semiconductor monolayer-MoS form a ferromagnetic state at low temperature. The Fermi sea consists of two circles, one at the -point, the other at the…
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…
A low-loss, broadband antenna for efficient photon collection from a coherent spin in diamond
D. Riedel, D. Rohner, M. Ganzhorn +5
We report the creation of a low-loss, broadband optical antenna giving highly directed output from a coherent single spin in the solid-state. The device, the first solid-state real…
