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 …

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 …

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

We review theoretical and experimental highlights in transport in two-dimensional
topological materials over the last five years. Topological materials comprise topological …

We perform microwave spectroscopy of Andreev states in superconducting weak links
tailored in an InAs-Al (core-full shell) epitaxially grown nanowire. The spectra present …

The protection against backscattering provided by topology is a striking property. In two-
dimensional insulators, a consequence of this topological protection is the ballistic nature of …

The interplay of superconductivity with non-trivial spin textures is promising for the
engineering of non-Abelian Majorana quasiparticles. Spin–orbit coupling is crucial for the …

The superconducting proximity effect in semiconductor nanowires has recently enabled the
study of new superconducting architectures, such as gate-tunable superconducting qubits …

Majorana bound states (MBSs) are quasiparticles that are their own antiparticles. They are
predicted to emerge as zero-energy modes localized at the boundary of a topological …
