Crystalline Germanium Josephson Junctions
Frederik H. Knudsen, Axel Leblanc, Patrick J. Strohbeen +8
Conventional superconducting quantum electronics rely on well-established Josephson junctions made of Al/AlO where the weak link AlO is amorphous and is believed to hos…
Digital Predistortion for Flux Control of Tunable Superconducting Qubits
Dharun Venkateswaran, Felice Francesco Tafuri, Yuanzheng Paul Tan +8
Flux-tunable superconducting qubits rely on fast flux control pulses to implement two-qubit entangling quantum gates, a key building block for quantum algorithms. However, distorti…
Superconductivity in Substitutional Ga-Hyperdoped Ge Epitaxial Thin Films
Julian A. Steele, Patrick J. Strohbeen, Carla Verdi +12
Doping-induced superconductivity in group IV elements may enable quantum functionalities in material systems accessible with well-established semiconductor technologies. Non-equili…
Machine learning analysis of structural data to predict electronic properties in near-surface InAs quantum wells
Patrick J. Strohbeen, Abtin Abbaspour, Amara Keita +12
Semiconductor crosshatch patterns in thin film heterostructures form as a result of strain relaxation processes and dislocation pile-ups during growth of lattice mismatched materia…
