What's the difference between quantum mobile phones and traditional mobile phones?

Quantum is the general name of some basic particles such as photons, protons, mesons, neutrons and electrons, and it is the most basic energy carrier. Quantum communication is a new form of communication that uses the principle of quantum mechanics to manipulate quantum states, and its main advantage is to solve the problem of information security. With scientists' in-depth understanding of quantum properties, various new practical technologies are gradually developed, and quantum communication is one of them. As a result, quantum mobile phones were developed. The difference between quantum mobile phones and traditional mobile phones is mainly in the following aspects:

1. Quantum mobile phone combines quantum keys prepared by quantum information technology.

Quantum key refers to the key prepared by quantum information technology. The so-called quantum key is to pre-charge the quantum key into the secure mobile phone SIM card, and encrypt the voice data when making a secure call through the mobile phone SIM card to prevent the content of voice transmission from being leaked. This kind of SIM card combines the functions of ordinary SIM card and security chip. It not only has the functions of SIM card such as network access authentication of ordinary operators, but also has the related functions of security chip. Therefore, users of quantum mobile phones enjoy the security functions of quantum mobile phones as well as the functions of traditional mobile phones.

2. Quantum mobile phones are more confidential.

Quantum has two characteristics? The measurement is random and unrepeatable. Therefore, in the process of quantum state transmission, if someone eavesdrops, its state will change due to measurement, which will lead to an increase in the bit error rate of signal reception, thus causing vigilance and stopping signal transmission. This characteristic of quantum phone also makes it impossible for eavesdroppers to obtain the information of legitimate users through information replication, so quantum communication has strong confidentiality.

3. Quantum mobile phones are more secure than traditional mobile phones.

The quantum secure phone is similar to the traditional secure phone in function, and it has made a new breakthrough in encryption and security. Quantum secure call service can be understood as? Secure call+quantum key? Our service is more secure than traditional mobile phones.
