Highly uniform quantum systems are essential for the practical implementation of scalable
quantum processors. While quantum dot spin qubits based on semiconductor technology …

Scaling up spin qubit systems requires high-fidelity single-qubit and two-qubit gates. Gate
fidelities exceeding 98% were already demonstrated in silicon-based single and double …

The energies of valley-orbit states in silicon quantum dots are determined by an as yet
poorly understood interplay between interface roughness, orbital confinement, and electron …

Proposals for large-scale semiconductor spin-based quantum computers require high-
fidelity single-shot qubit readout to perform error correction and read out qubit registers at …

Long-range interactions play a key role in several phenomena of quantum physics and
chemistry. To study these phenomena, analog quantum simulators provide an appealing …

We present an improved fabrication process for overlapping aluminum gate quantum dot
devices on Si/SiGe heterostructures that incorporates low-temperature inter-gate oxidation …

We investigate gate-induced quantum dots in silicon nanowire field-effect transistors
fabricated using a foundry-compatible fully depleted silicon-on-insulator (FD-SOI) process. A …

These notes are the result of a one-semester graduate course that was first taught during the
spring semester in 2003 at the CUNY Graduate Center and has been offered several times …

Quantum dots (QDs) defined with electrostatic gates are a leading platform for a scalable
quantum computing implementation. However, with increasing numbers of qubits, the …
