During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

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 …

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 …

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 …

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

Probing an isolated Majorana zero mode is predicted to reveal a tunneling conductance
quantized at 2 e 2/h at zero temperature. Experimentally, a zero-bias peak (ZBP) is expected …

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 …

The proximity effect in semiconductor-superconductor nanowires is expected to generate an
induced gap in the semiconductor. The magnitude of this induced gap, together with the …

The fusion of non-Abelian anyons or topological defects is a fundamental operation in
measurement-only topological quantum computation. In topological superconductors, this …
