Quantum information processing based on Rydberg atoms emerged as a promising
direction two decades ago. Recent experimental and theoretical progresses have shined …

This review describes recent groundbreaking results in Si, Si/SiGe, and dopant-based
quantum dots, and it highlights the remarkable advances in Si-based quantum physics that …

This article provides an introduction to surface code quantum computing. We first estimate
the size and speed of a surface code quantum computer. We then introduce the concept of …

Silicon is more than the dominant material in the conventional microelectronics industry: it
also has potential as a host material for emerging quantum information technologies …

Nanowires are natural one-dimensional channels and offer new opportunities for advanced
electronic quantum transport experiments. We review recent progress on the synthesis of …

Device physics and material science meet at the atomic scale of novel nanostructured
semiconductors, and the distinction between new device or new material is blurred. Not only …

We demonstrate rapid high-fidelity state preparation and measurement in exchange-only
Si/Si Ge triple-quantum-dot qubits. Fast measurement integration (980-ns) and initialization …

We demonstrate a hybrid device architecture where the charge states in a double quantum
dot (DQD) formed in a Si/SiGe heterostructure are read out using an on-chip …

We present an effective mass theory for Si Ge∕ Si∕ Si Ge quantum wells, with an emphasis
on calculating the valley splitting. The theory introduces a valley coupling parameter vv …

Quantum computers, if fully realized, promise to be a revolutionary technology. As a result,
quantum computing has become one of the hottest areas of research in the last few years …
