Quantum cryptography is a cryptographic communication method based on the principle of quantum mechanics. Its security is based on the non-reproducibility of quantum states and the interference of measurement. Although quantum cryptography is safe in theory, there are still some technical problems in practical applications, such as the stability of qubits and the transmission distance limit. Therefore, the current quantum cryptocommunication technology is still in the development stage and needs further research and experimental verification. In general, quantum crypto is a promising means of secure communication, but more research and practice are needed to improve its reliability and practicality.
Quantum secret talk is reliable, equipped with Tianyi 1 2022, the quantum security SIM card with domestic chips, and the quantum security middleware is independently developed to complete the encryption and decryption of VoLTE voice data on the mobile phone side, effectively preventing calls from being monitored during network transmission, and achieving end-to-end high-definition voice security calls.
