Decoherence and fidelity enhancement during shuttling of entangled spin qubits

Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Shuttling of spin qubits between different locations is a key element in many prospective semiconductor systems for quantum information processing, but the shuttled qubits should be protected from decoherence created by time- and space-dependent noises. Since the paths of […]

Trans-dimensional Hamiltonian model selection and parameter estimation from sparse, noisy data

Kavli Affiliate: Tim H. Taminiau | First 5 Authors: Abigail N. Poteshman, Abigail N. Poteshman, , , | Summary: High-throughput characterization often requires estimating parameters and model dimension from experimental data of limited quantity and quality. Such data may result in an ill-posed inverse problem, where multiple sets of parameters and model dimensions are consistent […]

XHEMTs on Ultrawide Bandgap Single-Crystal AlN Substrates

Kavli Affiliate: Grace Xing | First 5 Authors: Eungkyun Kim, Eungkyun Kim, , , | Summary: AlN has the largest bandgap in the wurtzite III-nitride semiconductor family, making it an ideal barrier for a thin GaN channel to achieve strong carrier confinement in field-effect transistors, analogous to silicon-on-insulator technology. Unlike SiO$_2$/Si/SiO$_2$, AlN/GaN/AlN can be grown […]
