Demonstration of Microwave Resonators and Double Quantum Dots on Optimized Reverse-Graded Ge/SiGe Heterostructures

Pasquale Scarlino, Fabian Oppliger, Franco De Palma

One of the most promising platforms for the realization of spin-based quantum computing are planar germanium quantum wells embedded between silicon-germanium barriers. To achieve comparably thin stacks with little surface roughness, this type of heterostru ...

Multi-Gate FD-SOI Single Electron Transistor for hybrid SET-MOSFET quantum computing

Mihai Adrian Ionescu, Pasquale Scarlino, Fabio Bersano, Fabian Oppliger, Franco De Palma

In this work we explore the fabrication and experimental characterization of multi-gate FD-SOI devices that can operate both as single electron transistors (SETs) and MOSFETs. FD-SOI SET operation is achieved with electrostatically induced tunneling barrie ...

Strong hole-photon coupling in planar Ge for probing charge degree and strongly correlated states

Pasquale Scarlino, Fabian Oppliger, Franco De Palma

Semiconductor quantum dots (QDs) in planar germanium (Ge) heterostructures have emerged as front-runners for future hole-based quantum processors. Here, we present strong coupling between a hole charge qubit, defined in a double quantum dot (DQD) in planar ...

Quantum Dots Array on Ultra-Thin SOI Nanowires with Ferromagnetic Cobalt Barrier Gates for Enhanced Spin Qubit Control

Pasquale Scarlino, Michele Ghini, Fabio Bersano, Fabian Oppliger, Eloi Régis L Collette, Franco De Palma, Heike Riel

In this work we propose and demonstrate the integration of ferromagnetic nanosized cobalt barrier gates in quantum dots arrays on ultra-thin fully-depleted Silicon-On-Insulator (SOI) nanowires. This innovative structure enhances both driving and addressabi ...
