The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

Abstract This Technical Review collects values of selected performance characteristics of
semiconductor spin qubits defined in electrically controlled nanostructures. The …

Electron spins hold great promise for quantum computation because of their long coherence
times. Long-distance coherent coupling of spins is a crucial step towards quantum …

Experimental and theoretical progress toward quantum computation with spins in quantum
dots (QDs) is reviewed, with particular focus on QDs formed in GaAs heterostructures, on …

Two level systems that can be reliably controlled and measured hold promise as qubits both
for metrology and for quantum information science. Since a fluctuating environment limits the …

The similarities between gated quantum dots and the transistors in modern microelectronics,—
in fabrication methods, physical structure and voltage scales for manipulation—have led to …

Semiconductors, a significant type of material in the information era, are becoming more and
more powerful in the field of quantum information. In recent decades, semiconductor …

Like modern microprocessors today, future processors of quantum information may be
implemented using all-electrical control of silicon-based devices. A semiconductor spin qubit …

We introduce a solid-state qubit in which exchange interactions among confined electrons
provide<? format?> both the static longitudinal field and the oscillatory transverse field …
