South Korean telecommunications giant SK Telecom and Samsung Electronics have collaborated to release the world's first new commercial 5G smartphone integrated with a quantum random number generator chip. Reservations will be accepted starting Friday.
On May 14th, the reporter was informed that South Korean telecommunications giant SK Telecom and Samsung Electronics jointly released the world's first commercialized 5G smartphone Galaxy A Quantum that integrates a quantum random number generator (QRNG) chip.
This 5G quantum mobile phone is equipped with four rear cameras, equipped with a 6.7-inch display and a 4500 mAh battery. The official listing time is May 22, and reservations will be accepted from Friday. Informed sources told reporters that the first mass production is expected to reach 1 million.
The
Today's world is highly interconnected, relying on mobile phones to process and store large amounts of personal data, and mobile applications also collect more and more sensitive information, including passwords, which increases users' demand for edge security.
Samsung's quantum encryption mobile phone solution is to use the light source shot noise captured by the CMOS image sensor to generate a random sequence. The QRNG chip can encrypt information by measuring the random number obtained by the optical quantum state, thereby increasing the difficulty of cracking the security of the password system. Once the quantum random number generation chip detects a failure, it can automatically recover and generate a new password again, and from the current technology point of view, there is basically no possibility of deciphering.
QRNG chip manufacturer Swiss quantum communication technology company ID Quantique sent an exclusive statement to reporters: "Samsung 5G mobile phones equipped with quantum random number generators will allow ordinary consumers to experience quantum security technology in their daily lives in the future. The benefits of the QRNG chipset allow smartphone users to use selected services in a safe and reliable manner by generating true random numbers that cannot be cracked. "
The new Galaxy A Quantum phone is priced at 649,000 won, or about $ 530. The reporter learned that integrating the QRNG chip will not significantly increase the production cost of the smartphone.
QRNG chips can be integrated on smart phones, which is not a small improvement. In 2017, South Korea's SK Telecom once launched a research quantum chip, which is not only large in size, but also reaches hundreds to thousands of dollars.
The cooperation between South Korea's SK Telecom and ID Quantique began in 2016, and the two companies collaborated to develop quantum communication technologies for the telecommunications and Internet of Things markets. Last year, SK Telecom used the QRNG system in its 5G mobile core network to improve the security of user authentication.
This cooperation is also a classic case of research and engineering development, cross-cooperation and collaborative innovation in the quantum field. Through the cooperation of three companies, it has opened up the quantum technology chain from research to application to development.
ID Quantique co-founder and CEO Gregoire Ribordy told reporters: "Smartphones and their applications can collect a large amount of personal and business information, and protecting the safety of smartphones has become a top priority for mobile operators, which will also bring them New income. "
The release of Samsung's first 5G quantum mobile phone also has more revenue sources for ID Quantique, because this mobile phone with integrated QRNG chip usually needs to be used in conjunction with eSim cards and quantum confidential data centers.
Quantum communication is considered to be the next-generation basic communication technology with high security and efficient transmission. The advent of quantum encryption mobile phones is undoubtedly a key step in the process of pushing quantum communication to practical use.
But experts pointed out that the quantum encrypted mobile phone is still far away from the actual application stage of quantum computing. A domestic company in the field of quantum computing told reporters: "Quantum technology is currently difficult to reach the application level, including quantum encrypted communication, quantum computing is farther away, even if the encryption of classic computing is used, the current encryption is safe enough Encryption has not yet shown its practical significance. "
Experts also emphasized that although the quantum random number generator is absolutely random, it does not guarantee that the information can be foolproof. It also depends on how to properly use it with the software.
