Novel radio frequency applications and automated characterisation of silicon quantum dots
… computers have revolutionised the 20th century, quantum computing could do the same in the 21st. For quantum supremacy, quantum error correcting codes will require an estimated million to billions of qubits. Regarding controlling and reading every qubit, classical electronics must be as close to …

Electronic and optical characterisations of silicon quantum dots and its applications in solar cells
… optical and electrical properties of crystalline silicon quantum dots (SiQDs) are examined for application to silicon based tandem cells. The approach has been to concentrate on all silicon devices by taking advantage of quantum confinement in low-dimensional Si. RF magnetron co-sputtering …

One- and two-qubit operations in Si-MOS quantum dots
Quantum computers have potential to solve hard problems that even the most advanced supercomputers are not capable of, such as prime factoring, database search, and quantum simulation. Quantum bits, or qubits, made from silicon quantum dots is one scalable approach that can be used to realize a …

Theoretical study of nanocrystals and other functional nanostructures of silicon and alternative group - 14 elements
… present work is a theoretical ab initio study of silicon (mainly) and silicon-based or “silicon-like” Nanocrystals and nanostructures, such as core/shell quantum dots and ultra-thin nanowires of Si, Ge, and Sn. The main focus is on the quantum confinement of Si quantum dots and the description of …
