Electron-hole superfluidity in strained Si/Ge type II heterojunctions
Sara Conti, Samira Saberi Pouya, Andrea Perali +5
Excitons are promising candidates for generating superfluidity and Bose-Einstein Condensation (BEC) in solid state devices, but an enabling material platform with in-built bandstru…
Enhancement of Proximity Induced Superconductivity in a Planar Ge Hole Gas
Kushagra Aggarwal, Andrea Hofmann, Daniel Jirovec +9
Hole gases in planar germanium can have high mobilities in combination with strong spin-orbit interaction and electrically tunable g-factors, and are therefore emerging as a promis…
A four-qubit germanium quantum processor
N. W. Hendrickx, W. I. L. Lawrie, M. Russ +6
The prospect of building quantum circuits using advanced semiconductor manufacturing positions quantum dots as an attractive platform for quantum information processing. Extensive…
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…
Spin relaxation benchmarks and individual qubit addressability for holes in quantum dots
W. I. L. Lawrie, N. W. Hendrickx, F. van Riggelen +5
We investigate hole spin relaxation in the single- and multi-hole regime in a 2x2 germanium quantum dot array. We use radiofrequency (rf) charge sensing and observe Pauli Spin-Bloc…
Effect of quantum Hall edge strips on valley splitting in silicon quantum wells
Brian Paquelet Wuetz, Merritt P. Losert, Alberto Tosato +10
We determine the energy splitting of the conduction-band valleys in two-dimensional electrons confined to low-disorder Si quantum wells. We probe the valley splitting dependence on…
