Abstract: When working across different devices, moving a file securely from a phone to a laptop is surprisingly annoying. People usually end up emailing files to themselves or logging into a cloud drive just for one small transfer. This not only wastes time but also leaves junk data sitting on third-party servers forever. To fix this, we built QuantumDrive, a simple web app that lets you transfer files directly without forcing you to make an account. We used React for the frontend and Node.js for the server. Instead of saving your files permanently, the app encrypts them right inside your browser. The receiver then downloads the file using a temporary QR code, and the file gets deleted from the server shortly after. This paper explains how we designed the app, how the encryption works, and what we learned while building it during our internship.
