Tianyi No. 1 2022 (smartphone with quantum encryption)

History

2022: Device announcement

On May 16, 2022, the Chinese company China Telecom released its first smartphone with a quantum encryption module - Tianyi No. 1 2022. The device was developed together with the startup QuantumCTek.

Unlike traditional cryptography, the technology used in the phone uses single photons in quantum superposition states that embed a key to ensure unconditional security between remote parties. Quantum superposition is a fundamental principle of quantum mechanics, which states that, like waves in classical physics, any two or more quantum states can be folded together. Therefore, communication cannot be hacked, since any attempt to intercept the key will immediately be known to both the sender and the intended recipient.

{{quote 'When a user starts a quantum secure chat, a secret key is generated randomly to verify their identity. After verification, the quantum network generates a new real-time key for encrypting voice data. Such a key is generated randomly, it is difficult to hack, and it must be thrown out immediately after the call. Then the service becomes available when both the sender and the recipient use the phone on a quantum basis, "said QuantumCTeck engineer Zhang Rutong. }} Model Tianyi No. 1 2022 is equipped with an encryption module with quantum protection and a specially developed SIM card, which can encrypt and decrypt voice calls on a phone using quantum key exchange.

According to information China Daily, the Tianyi No. 1 2022 smartphone is equipped with a 6.5-inch screen with a resolution of 1080p and a frequency of 90 Hz. The device also received a 5000 mAh battery and 128 GB of permanent memory. It is planned to release two versions of the device with 6 and 8 GB of RAM.^[1]
