Radio frequency readout and control of Ge/SiGe hole spin qubits with a global accumulation gate
Tien-Ho Chang, Chi-Wei Lee, Jian-Chang Zeng +12
Hole spin qubits in undoped Ge/SiGe quantum well structures have advanced rapidly in performance and scalability. However, stringent multi-layer patterning and overlay requirements…
Universal control of four singlet-triplet qubits
Xin Zhang, Elizaveta Morozova, Maximilian Rimbach-Russ +9
The coherent control of interacting spins in semiconductor quantum dots is of strong interest for quantum information processing as well as for studying quantum magnetism from the…
Exciton transport in a germanium quantum dot ladder
T. -K. Hsiao, P. Cova Fariña, S. D. Oosterhout +10
Quantum systems with engineered Hamiltonians can be used as simulators of many-body physics problems to provide insights beyond the capabilities of classical computers. Semiconduct…
Long-range electron-electron interactions in quantum dot systems and applications in quantum chemistry
Johannes Knörzer, Cornelis J. van Diepen, Tzu-Kan Hsiao +6
Long-range interactions play a key role in several phenomena of quantum physics and chemistry. To study these phenomena, analog quantum simulators provide an appealing alternative…
Quantum simulation of antiferromagnetic Heisenberg chain with gate-defined quantum dots
C. J. van Diepen, T. -K. Hsiao, U. Mukhopadhyay +3
Quantum-mechanical correlations of interacting fermions result in the emergence of exotic phases. Magnetic phases naturally arise in the Mott-insulator regime of the Fermi-Hubbard…
Low percolation density and charge noise with holes in germanium
M. Lodari, N. W. Hendrickx, W. I. L. Lawrie +5
We engineer planar Ge/SiGe heterostructures for low disorder and quiet hole quantum dot operation by positioning the strained Ge channel 55~nm below the semiconductor/dielectric in…
Efficient orthogonal control of tunnel couplings in a quantum dot array
T. -K. Hsiao, C. J. van Diepen, U. Mukhopadhyay +3
Electrostatically-defined semiconductor quantum dot arrays offer a promising platform for quantum computation and quantum simulation. However, crosstalk of gate voltages to dot pot…
Quantised Charge Transport driven by a Surface Acoustic Wave in induced unipolar and bipolar junctions
Yousun Chung, Hangtian Hou, Seok-Kyun Son +7
Surface acoustic waves (SAWs) have been used to transport single electrons across long distances of several hundreds of microns. They can potentially be instrumental in the impleme…
Single-photon Emission from an Acoustically-driven Lateral Light-emitting Diode
Tzu-Kan Hsiao, Antonio Rubino, Yousun Chung +12
Single-photon sources are essential building blocks in quantum photonic networks, where quantum-mechanical properties of photons are utilised to achieve quantum technologies such a…
Experimental verification of electrostatic boundary conditions in gate-patterned quantum devices
H. Hou, Y. Chung, G. Rughoobur +7
In a model of a gate-patterned quantum device it is important to choose the correct electrostatic boundary conditions (BCs) in order to match experiment. In this study, we model ga…
