Cavity-mediated coherent coupling between distant quantum dots
Giorgio Nicolí, Michael Sven Ferguson, Clemens Rössler +7
Scalable architectures for quantum information technologies require to selectively couple long-distance qubits while suppressing environmental noise and cross-talk. In semiconducto…
Coherent spin-qubit photon coupling
A. J. Landig, J. V. Koski, P. Scarlino +7
Electron spins hold great promise for quantum computation due to their long coherence times. An approach to realize interactions between distant spin-qubits is to use photons as ca…
All-Microwave Control and Dispersive Readout of Gate-Defined Quantum Dot Qubits in Circuit Quantum Electrodynamics
P. Scarlino, D. J. van Woerkom, A. Stockklauser +8
Developing fast and accurate control and readout techniques is an important challenge in quantum information processing with semiconductor qubits. Here, we study the dynamics and t…
Non-linear and dot-dependent Zeeman splitting in GaAs/AlGaAs quantum dot arrays
V. P. Michal, T. Fujita, T. A. Baart +5
We study the Zeeman splitting in lateral quantum dots that are defined in GaAs-AlGaAs het- erostructures by means of split gates. We demonstrate a non-linear dependence of the spli…
Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
A capacitance spectroscopy-based platform for realizing gate-defined electronic lattices
T. Hensgens, U. Mukhopadhyay, P. Barthelemy +6
Electrostatic confinement in semiconductors provides a flexible platform for the emulation of interacting electrons in a two-dimensional lattice, including in the presence of gauge…
Finite shot noise and electron heating at quantized conductance in high-mobility quantum point contacts
Tatsuya Muro, Yoshitaka Nishihara, Shota Norimoto +8
We report a precise experimental study on the shot noise of a quantum point contact (QPC) fabricated in a GaAs/AlGaAs based high-mobility two-dimensional electron gas (2DEG). The c…
Optical probing of the intrinsic spin Hall effect in a high mobility GaAs p-doped quantum well
Adrian Maier, Christian Reichl, Stefan Riedi +2
We report on the detection of the intrinsic spin Hall effect in a modulation doped Al-GaAs/GaAs/AlGaAs heterostructure bounded by a self-aligned pn-junction, fabricated by the clea…
Quantum simulation of a Fermi-Hubbard model using a semiconductor quantum dot array
T. Hensgens, T. Fujita, L. Janssen +6
Interacting fermions on a lattice can develop strong quantum correlations, which lie at the heart of the classical intractability of many exotic phases of matter. Seminal efforts a…
Fermi edge singularities in transport through lateral GaAs quantum dots
Tobias Krähenmann, Livio Ciorciaro, Christian Reichl +4
We measure tunnelling currents through electrostatically defined quantum dots in a GaAs/AlGaAs heterostructure connected to two leads. For certain tunnelling barrier configurations…
Strong Coupling Cavity QED with Gate-Defined Double Quantum Dots Enabled by a High Impedance Resonator
Anna Stockklauser, Pasquale Scarlino, Jonne Koski +7
The strong coupling limit of cavity quantum electrodynamics (QED) implies the capability of a matter-like quantum system to coherently transform an individual excitation into a sin…
Coherent shuttle of electron-spin states
T. Fujita, T. A. Baart, C. Reichl +2
We demonstrate a coherent spin shuttle through a GaAs/AlGaAs quadruple-quantum-dot array. Starting with two electrons in a spin-singlet state in the first dot, we shuttle one elect…
