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 …

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 …

We present measurements and simulations of semiconductor-superconductor
heterostructure devices that are consistent with the observation of topological …

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

Motivated by the need to understand and simulate the ubiquitous experimentally observed
zero-bias conductance peaks in superconductor-semiconductor hybrid structures, we …

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 …

Selective area epitaxy (SAE) can be used to grow highly uniform III–V nanostructure arrays
in a fully controllable way and is thus of great interest in both basic science and device …

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

Majorana zero modes are localized quasiparticles that obey non-Abelian exchange
statistics. Braiding Majorana zero modes forms the basis of topologically protected quantum …
