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 …

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 …

After a brief introduction to the principles and promise of quantum information processing,
the requirements for the physical implementation of quantum computation are discussed …

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 …

The fabrication methods of the microelectronics industry have been refined to produce ever
smaller devices, but will soon reach their fundamental limits. A promising alternative route to …

The electronic spin degrees of freedom in semiconductors typically have decoherence times
that are several orders of magnitude longer than other relevant time scales. A solid-state …

Quantum computation requires many qubits that can be coherently controlled and coupled
to each other. Qubits that are defined using lithographic techniques have been suggested to …

In the effort to develop disruptive quantum technologies, germanium is emerging as a
versatile material to realize devices capable of encoding, processing and transmitting …

Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …
