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 …

Over the past several decades, quantum information science has emerged to seek answers
to the question: can we gain some advantage by storing, transmitting and processing …

Open any textbook on quantum mechanics, and the two-state system of choice is likely to be
a spin-½ particle, such as an electron. The corresponding states, spin up and spin down …

During the past few years, researchers have gained unprecedented control over spins in the
solid state. What was considered almost impossible a decade ago, in both conceptual and …

Quantum computers hold the promise of massive performance enhancements across a
range of applications, from cryptography and databases to revolutionary scientific simulation …

We propose a quantum dot qubit architecture that has an attractive combination of speed
and fabrication simplicity. It consists of a double quantum dot with one electron in one dot …

Arrays of quantum dots (QDs) are a promising candidate system to realize scalable, coupled
qubit systems and serve as a fundamental building block for quantum computers. In such …

Double quantum dots are convenient solid-state platforms to encode quantum information.
Two-electron spin states can be detected and manipulated using quantum selection rules …

Among quantum devices based on 2D materials, gate-defined quantum confined 1D
channels are much less explored, especially in the high-mobility regime where many-body …

We investigate the gate-induced onset of few-electron regime through the undoped channel
of a silicon nanowire field-effect transistor. By combining low-temperature transport …
