Electronic correlations give rise to fascinating macroscopic phenomena such as
superconductivity, magnetism, and topological phases of matter. Although these …

Scalable quantum computing can become a reality with error correction, provided that
coherent qubits can be constructed in large arrays,. The key premise is that physical errors …

Error-corrected quantum computers can only work if errors are small and uncorrelated. Here,
I show how cosmic rays or stray background radiation affects superconducting qubits by …

Connecting double quantum dots via a semiconductor-superconductor hybrid segment
offers a platform for creating a two-site Kitaev chain that hosts Majorana zero modes at a …

Superconducting devices, based on the Cooper pairing of electrons, play an important role
in existing and emergent technologies, ranging from radiation detectors, to quantum …

We develop a protocol to determine the presence and extent of a topological phase with
Majorana zero modes in a hybrid superconductor-semiconductor device. The protocol is …

We address an outstanding problem that represents a critical roadblock in the development
of the Majorana-based topological qubit using semiconductor-superconductor hybrid …

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

Quantum error correction will be an essential ingredient in realizing fault-tolerant quantum
computing. However, most correction schemes rely on the assumption that errors are …

Magnetic impurities in s-wave superconductors lead to spin-polarized Yu-Shiba-Rusinov
(YSR) in-gap states. Chains of magnetic impurities offer one of the most viable routes for the …
