BACKGROUND Semiconductor materials feature optical and electronic properties that can
be engineered through their composition and crystal structure. The use of semiconductors …

Over the past several decades, quantum information science has emerged to seek answers
to the question: can we gain some advantage by storing, transmitting and processing …

As a consequence of degeneracies arising from crystal symmetries, it is possible for electron
states at band-edges ('valleys') to have additional spin-like quantum numbers,,,,,. An …

Carbon nanotubes are a versatile material in which many aspects of condensed matter
physics come together. Recent discoveries have uncovered new phenomena that …

Improving the quantum coherence of solid-state systems that mimic two-level atoms, for
instance spin qubits or single-photon emitters using semiconductor quantum dots, involves …

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 …

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 …

Realization of a quantum interface between stationary and flying qubits is a requirement for
long-distance quantum communication and distributed quantum computation. The prospects …

Spin defects in foils of hexagonal boron nitride are an attractive platform for magnetic field
imaging, since the probe can be placed in close proximity to the target. However, as a III-V …

Qubits, the quantum mechanical bits required for quantum computing, must retain their
quantum states for times long enough to allow the information contained in them to be …
