Topological insulators (TIs) hold promise as a platform for unique quantum phenomena.
However, realizing these phenomena experimentally requires sophisticated devices. In this …

Nanowires are natural one-dimensional channels and offer new opportunities for advanced
electronic quantum transport experiments. We review recent progress on the synthesis of …

Majorana bound states constitute one of the simplest examples of emergent non-Abelian
excitations in condensed matter physics. A toy model proposed by Kitaev shows that such …

In most naturally occurring superconductors, electrons with opposite spins form Cooper
pairs. This includes both conventional s-wave superconductors such as aluminium, as well …

A short superconducting segment can couple attached quantum dots via elastic cotunneling
(ECT) and crossed Andreev reflection (CAR). Such coupled quantum dots can host …

Kitaev chains in quantum dot-superconductor arrays are a promising platform for the
realization of topological superconductivity. As recently demonstrated, even a two-site chain …

Majorana bound states are quasiparticle excitations localized at the boundaries of a
topologically nontrivial superconductor. They are zero-energy, charge-neutral, particle–hole …

The formation of a topological superconducting phase in a quantum-dot–based Kitaev chain
requires nearest neighbor crossed Andreev reflection and elastic cotunneling. Here, we …

The proximity effect in semiconductor-superconductor nanowires is expected to generate an
induced gap in the semiconductor. The magnitude of this induced gap, together with the …

The co-integration of spin, superconducting, and topological systems is emerging as an
exciting pathway for scalable and high-fidelity quantum information technology. High …
