Starting with the simplest semiclassical approaches and ending with the description of
complex fully quantum-mechanical methods for quantum transport analysis of state-of-the …

Abstract Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction
band valleys, which compete with the spin degree of freedom in the formation of qubits …

Exploiting the power of quantum computation to realize superior machine learning
algorithms has been a major research focus of recent years, but the prospects of quantum …

Practical quantum computers require a large network of highly coherent qubits,
interconnected in a design robust against errors. Donor spins in silicon provide state-of-the …

Large-scale arrays of quantum-dot spin qubits in Si/SiGe quantum wells require large or
tunable energy splittings of the valley states associated with degenerate conduction band …

We develop an atomistic, nearest-neighbor sp 3 s* tight-binding Hamiltonian to investigate
the electronic structure of dilute bismide alloys of GaP and GaAs. Using this model, we …

The ability to build structures with atomic precision is one of the defining features of
nanotechnology. Achieving true atomic-level functionality, however, requires the ability to …

Silicon/silicon-germanium heterostructures have many important advantages for hosting
spin qubits. However, controlling the valley splitting (the energy splitting between the two …

Large-scale quantum computers must be built upon quantum bits that are both highly
coherent and locally controllable. We demonstrate the quantum control of the electron and …

The development of a new nanoelectronics modeling tool, NEMO5, is reported. The tool
computes strain, phonon spectra, electronic band structure, charge density, charge current …
