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 …

Topological superconductivity can emerge from the combination of conventional
superconductivity in a metal and strong spin–orbit coupling in a semiconductor when they …

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 …

Topological superconductors are an essential component for topologically protected
quantum computation and information processing. Although signatures 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 …

The emergence of superconductivity in 2D materials has attracted much attention and there
has been rapid development in recent years because of their fruitful physical properties …

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

Over the past decade, there have been considerable efforts to observe non-abelian
quasiparticles in novel quantum materials and devices. These efforts are motivated by the …

We propose and theoretically investigate an alternative way to create the poor man's
Majorana bound states (MBSs) introduced in Phys. Rev. B 86, 134528 (2012) …
