China Unicom CITTI Launches Quantum Security Phone 2.0 with On-Device AI
China Unicom's CITTI has officially released Quantum Security Phone 2.0, upgrading its secure smartphone platform with 100% domestic hardware and on-device offline risk control AI. The device combines quantum SIM cards containing quantum random number generator (QRNG) chips with encrypted workspace tools and China Unicom's UniClaw AI agents. The release demonstrates China's strategy to integrate quantum encryption with localized AI processing to safeguard confidential data within government agencies and state-owned enterprises. It illustrates how telecom operators are bundling hardware security chips, post-quantum defenses, and offline AI capabilities into specialized products for high-compliance enterprise sectors. Built on customized Chinese domestic flagship handsets, the solution relies on a quantum SIM card featuring national cryptography and QRNG chips to encrypt voice calls, video meetings, and file transfers. Its security architecture includes an on-device offline AI risk control engine and localized speech transcription, ensuring sensitive operational data never leaves the terminal.
## BACKGROUND
Quantum security smartphones typically combine standard mobile hardware with Quantum Random Number Generators (QRNG) embedded in specialized SIM cards or chips to produce unpredictable encryption keys. In China, public sector organizations and critical infrastructure state-owned enterprises increasingly demand end-to-end encrypted mobile ecosystems built on 100% domestic supply chains to prevent data leaks and wiretapping.
