Abstract: Multi-channel sensing circuit utilizing wavelength division multiplexing is proposed using silicon on insulator platform. The circuit consists of four sections that can be decomposed into a ...

Abstract: Three-dimensional topological insulators (TIs) have become an interesting platform for future high-speed electronics. The massless Dirac fermions in topologically protected surface states ...

A topological superconductor is a unique material that, at its surface, hosts new quantum particles named Majorana fermions. In theory, they can be used to stably store quantum information without ...
