We demonstrated coherent control of a quantum two-level system based on two-electron
spin states in a double quantum dot, allowing state preparation, coherent manipulation, and …

Hybrid nanowires combining semiconductor and superconductor materials appear well suited
for the creation, detection, and control of Majorana bound states (MBSs). We demonstrate …

Realizing topological superconductivity and Majorana zero modes in the laboratory is a
major goal in condensed-matter physics. In this Review, we survey the current status of this …

We present transport measurements in superconductor-nanowire devices with a gated
constriction forming a quantum point contact. Zero-bias features in tunneling spectroscopy …

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

We present designs for scalable quantum computers composed of qubits encoded in
aggregates of four or more Majorana zero modes, realized at the ends of topological …

The ongoing miniaturization of solid state devices often leads to the question: “How small
can we make resistors, transistors, etc., without changing the way they work?” The question …

Controlling the properties of semiconductor/metal interfaces is a powerful method for
designing functionality and improving the performance of electrical devices. Recently …

Strong electron–electron interactions in graphene are expected to result in multiple-excitation
generation by the absorption of a single photon. We show that the impact of carrier …

We study photodetection in graphene near a local electrostatic gate, which enables active
control of the potential landscape and carrier polarity. We find that a strong photoresponse …
