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 …

We introduce a scheme for preparation, manipulation, and read out of Majorana zero modes
in semiconducting wires with mesoscopic superconducting islands. Our approach …

We introduce a hybrid qubit based on a semiconductor nanowire with an epitaxially grown
superconductor layer. Josephson energy of the transmonlike device (“gatemon”) is …

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

We report the realization of quantum microwave circuits using hybrid superconductor-
semiconductor Josephson elements comprised of InAs nanowires contacted by NbTiN …

We realize a hybrid superconductor-semiconductor transmon device in which the
Josephson effect is controlled by a gate-defined quantum dot in an In As-Al nanowire …

Minimal Kitaev chains composed of two semiconducting quantum dots coupled via a
superconductor have emerged as a promising platform to realize and study Majorana bound …

We show how to realize fast and high-fidelity quantum nondemolition qubit readout using
longitudinal qubit-oscillator interaction. This is accomplished by modulating the longitudinal …

A striking characteristic of superconducting circuits is that their eigenspectra and intermode
coupling strengths are well predicted by simple Hamiltonians representing combinations of …
