Gate-defined Quantum Dot Qubits Based on Light Holes in Strained Ge Heterostructures- Material Property Correlations and Predictive Performance Metrics

Abstract

This project delves into the innovative domain of quantum computing, an emerging technology with the potential to revolutionize problem-solving in various fields, from medicine to cybersecurity. The cornerstone of quantum computing lies in qubits, akin to bits in classical computing, but with the ability to perform complex computations at an unprecedented scale. The effectiveness of qubits hinges on the materials used to construct them, and this project aims to unravel the relationship between material properties and qubit performance, setting the stage for high-performance qubits. NCSU led team have chosen tensile-strained germanium as the focal point of our study. This specially engineered germanium forms a unique bridge between quantum and optical systems, allowing for the efficient manipulation and transmission of quantum data. Furthermore, it relies on light holes instead of the conventional heavy holes, making qubits less susceptible to environmental interference and more stable for information storage.
