Interactive and accessible quantum key distribution modules for introducing students to quantum science and engineering

Teaching key concepts in quantum information science and technology benefits from hands-on activities that can engage students at all levels, especially high-school and undergraduate students. In this paper, we report on an educational kit for student exploration of quantum key distribution (QKD) via optical analogies that provides an affordable and highly interactive role-playing experience for students with minimal abstraction and direct connections to applications, key quantum concepts like superposition and measurement uncertainty, and student's pre-existing knowledge like light polarization. Manual and automated versions of the kit are detailed, as well as feedback from workshops with high-school students, undergraduates, and educators.

Junction-less nanowire based photodetector: Role of nanowire width

Enhanced photocurrent is demonstrated in a junction-less photodetector with nanowires embedded in its channel. The fabricated photodetector consists of a large area for efficient absorption of incident light with energy band engineering achieved in nanowires. The structure design consists of a set of two symmetrically positioned gates, primary and secondary, that are located over the nanowires. Each gate is used for biasing and control of the charge flow. We find that detectors with narrower nanowires controlled by their secondary gate generate larger photocurrents under similar illumination conditions. Our results show that while the dark current remains the same, the photocurrent increases as the nanowire width decreases.
