Atom by atom: Fabricating materials for a quantum computer 

Topological qubits will be one of the key ingredients in the Microsoft plan to bring a powerful, scalable quantum computing solution to the world. Providing increased resistance to outside interference, topological qubits create a more stable foundation than conventional qubits. This increased stability allows the quantum computer to perform computations that can uncover solutions to...

Anomalous Fraunhofer Interference in Epitaxial Superconductor-Semiconductor Josephson Junctions 

  Last year saw a materials breakthrough, with the realization of a two-dimensional heterostructure combining superconductor and semiconductor layers. (See journals.aps.org/prb/abstract/10.1103/PhysRevB.93.15540.) Now, as shown in a recent report, this material has been used to study interference effects controlled by magnetic fields in a Josephson junction made from this material. Anomalous interference reveals properties of the semiconductor in...
