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

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 …

We analyze the quantum trajectory dynamics of free fermions subject to continuous
monitoring. For weak monitoring, we identify a novel dynamical regime of subextensive …

Lead has recently been expelled from many commercial applications and materials (for
example, from solder, glass and pottery glaze) owing to concerns regarding its toxicity. Lead …

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 …

Spin is a fundamental property of all elementary particles. Classically it can be viewed as a
tiny magnetic moment, but a measurement of an electron spin along the direction of an …

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 …

Cesium lead halide perovskites exhibit outstanding optical and electronic properties for a
wide range of applications in optoelectronics and for light-emitting devices. Yet, the physics …

Abstract Cr 2 Ge 2 Te 6 has been of interest for decades, as it is one of only a few naturally
forming ferromagnetic semiconductors. Recently, this material has been revisited due to its …
