Our overarching mission is to accelerate two-dimensional materials research for quantum technologies in the US.

Introduction

In quantum machine field, detecting two-dimensional (2D) materials in Silicon chips is one of the most critical problems. It is considered as one of bottlenecks in quantum research because of time and labor consumptions spent on finding a potential flake that might be useful. This progress takes hours to finish without any warranty that detected flakes being helpful. In order to speedup, reduce cost and efforts of this progress, we leverage computer vision and AI to build an end-to-end system for automatically identifying potential flakes and exploring their charactersitics (e.g thickness).

2D Quantum Crystals Identification

We provide a flexible and generalized solution for 2D quantum crystals identification running on realtime with high accuracy. The algorithm is able to work with any kind of flakes (e.g hBN, Graphine, etc), hardware and environmental settings. It will help to reduces time and labor consumption in research of quantum technologies.

Quantum Neural Networks

Classical neural network algorithms are computationally expensive. For example, in image classification, representing an image pixel by pixel using classical information requires an enormous amount of computational memory resources. Hence, exploring methods to represent images in a different paradigm of information is important. We proposed a parameter encoding scheme for defining and training neural networks in quantum information based on time evolution of quantum spaces.
