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 Read more
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 Read more
In this paper, we show by computer simulations that a new material, which is a specific combination of the two semiconductors InAs and InSb (both are currently used in experimental setups on Majorana zero modes), has vastly improved properties compared to InAs or InSb alone, making it ideally suited for future devices. Moreover, we Read more
