Quantum Randomness for Secure Password Generation
Abstract
This paper presents a practical demonstration of quantum random number generation (QRNG) for secure password and key creation, leveraging the intrinsic unpredictability of quantum measurement. While classical pseudo-random number generators (PRNGs) are deterministic and potentially vulnerable if the seed or algorithm is exposed, QRNGs exploit the collapse of quantum superposition to generate fundamentally unpredictable outcomes. Using IBM Quantum’s cloud-accessible superconducting qubits, we implement an end-to-end pipeline that produces high-entropy 8-bit passwords. The process involves preparing qubits in superposition states via Hadamard gates, followed by measurement to extract true random bits. We compare results from an ideal simulator to those obtained from a real quantum processing unit (QPU), visualizing deviations caused by hardware noise. The experiment confirms that even with physical imperfections, real QPU outputs retain sufficient entropy for use in cryptographic contexts. We further illustrate how the resulting bit strings can be converted into secure PINs or cryptographic seeds, and discuss applications in distributed identity, secure communications, and lottery systems. This work highlights the feasibility of deploying accessible, reproducible QRNG workflows using today’s quantum infrastructure, bridging the gap between theoretical quantum security and real-world use cases.
