Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

We demonstrated coherent control of a quantum two-level system based on two-electron
spin states in a double quantum dot, allowing state preparation, coherent manipulation, and …

The canonical example of a quantum-mechanical two-level system is spin. The simplest
picture of spin is a magnetic moment pointing up or down. The full quantum properties of …

In this perspective, we focus on a new type of quantum dots, graphene quantum dots
(GQDs). Due to quantum confinement and edge effects, GQDs have presented extraordinary …

Understanding and controlling the complex environment of solid-state quantum bits is a
central challenge in spintronics and quantum information science. Coherent manipulation of …

The greatest challenge in quantum computing is achieving scalability. Classical computing,
which previously faced such issues, currently relies on silicon chips hosting billions of fin …

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

The main characteristics of good qubits are long coherence times in combination with fast
operating times. It is well known that carbon-based materials could increase the coherence …

Manipulation of single spins is essential for spin-based quantum information processing.
Electrical control instead of magnetic control is particularly appealing for this purpose …
