Bank IT Firms Enter Quantum Technology, Large-Scale Deployment Still Needs Time
Recently, Colorbeyond Software signed a strategic cooperation agreement with Shanghai Turing Quantum Technology to build a chain linking quantum underlying hardware, quantum security infrastructure, financial computing services, and banking business systems. At present, companies whose main or core business involves bank IT and that have publicly disclosed quantum technology products, cooperation, investment, or project progress include at least Digital China, Global InfoTech, Colorbeyond Software, and Tianyang Technology, with layouts covering quantum communication, post-quantum cryptography, and quantum computing. Among them, Digital China already has application cases at financial institutions, Global InfoTech and Colorbeyond Software mainly enter through industrial cooperation, and Tianyang Technology starts with investment and industrial alliances. However, large-scale deployment of quantum technology in the financial sector still faces multiple hurdles, including technology maturity, compatibility with existing systems, and the measurability of input and output. Experts point out that the two technical routes of quantum key distribution and post-quantum cryptography are still developing in parallel. If financial institutions invest heavily in dedicated hardware too early, they may face sunk costs brought by adjustments in technical routes.
