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 …

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 …

The ability to control the quantum state of a single electron spin in a quantum dot is at the
heart of recent developments towards a scalable spin-based quantum computer. In …

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 …

Crosstalk occurs in most quantum computing systems with more than one qubit. It can cause
a variety of correlated and nonlocal $\textit {crosstalk errors} $ that can be especially harmful …

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 …

The rapid rise of spintronics and quantum information science has led to a strong interest in
develo** the ability to coherently manipulate electron spins. Electron spin resonance is a …

Technological challenges for quantum information technologies lead us to consider aspects
of molecular magnetism in a radically new perspective. The design of new derivatives and …
