Quantum computers are moving so quickly that they now threaten the cryptographic tools banks rely on every day. Shorts algorithm alone puts RSA and ECC at risk, and even Grovers speed-up shortens the lifespan of most symmetric keys. Faced with these dangers, the finance industry must switch to quantum-safe schemes without delay. This study reviews the newest post-quantum options that are being built for payments, lending, and other banking functions. Drawing on NISTs standardization work, live pilots at top banks, and head-to-head tests of lattice, code, multivariate, hash, and isogeny methods, we map out practical upgrade paths. Our analysis finds that lattice packages such as CRYSTALS-Kyber and Di lithium strike the best balance of performance and maturity today, while hybrid setups and crypto-agility keep systems future-proof. We therefore urge firms to roll out new algorithms in stages, work with regulators, and share lessons across the sector so they remain secure in a quantum world.

Electronic voting systems face growing risks from cyberattacks and data breaches, which are expected to intensify with the advent of quantum computing. To address these challenges, we introduce a quantum-secure voting framework that integrates Quantum Key Distribution (QKD), Dual-Key Symmetric Encryption, and verifiable receipt mechanisms to strengthen the privacy, integrity, and reliability of the voting process. The framework enables voters to establish encryption keys securely, cast encrypted ballots, and verify their votes through receipt-based confirmation, all without exposing the vote contents. To evaluate performance, we simulate both quantum and classical communication channels using the Message Queuing Telemetry Transport (MQTT) protocol. Results demonstrate that the system can process large numbers of votes efficiently with low latency and minimal error rates. This approach offers a scalable and practical path toward secure, transparent, and verifiable electronic voting in the quantum era.
