Among the major avenues that are being pursued for realizing quantum bits, the Majorana-
based approach has been the most recent to be launched. It attempts to realize qubits that …

Inhomogeneous superconductors can host electronic excitations, known as Andreev bound
states (ABSs), below the superconducting energy gap. With the advent of topological …

The possibility of engineering artificial Kitaev chains in arrays of quantum dots coupled via
narrow superconducting regions has emerged as an attractive way to overcome the disorder …

Realizing topological superconductivity and Majorana zero modes in the laboratory is a
major goal in condensed-matter physics. In this Review, we survey the current status of this …

Majorana zero-modes—a type of localized quasiparticle—hold great promise for topological
quantum computing. Tunnelling spectroscopy in electrical transport is the primary tool for …

Artificial Kitaev chains can be used to engineer Majorana bound states (MBSs) in
superconductor–semiconductor hybrids,,–. In this work, we realize a two-site Kitaev chain in …

In the space of less than one decade, the search for Majorana quasiparticles in condensed
matter has become one of the hottest topics in physics. The aim of this review is to provide a …

Motivated by an important recent experiment [Deng, Science 354, 1557 (2016) SCIEAS
0036-8075 10.1126/science. aaf3961], we theoretically consider the interplay between …

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

Andreev bound states in hybrid superconductor-semiconductor devices can have near-zero
energy in the topologically trivial regime as long as the confinement potential is sufficiently …
