## FAQ

1. **What is the GNA Quantum Chip?**

   * **Answer**: The GNA Quantum Chip is a true random number generator that utilizes alpha particles generated by the natural decay of atomic nuclei. This random number generator supports authentication systems and cryptographic communications, providing high-level security.

2. **How does the GNA Quantum Chip generate random numbers?**

   * **Answer**: The GNA Quantum Chip generates random numbers by utilizing the alpha decay of the radioactive isotope Am241. Am241 emits alpha particles, which are detected to generate random numbers. The half-life of Am241 is 432 years. The decay rate is measured over a certain period, and the results are used to calculate the random numbers. Researchers worldwide verify these measurements and calculations, and updates are made when new insights are obtained. The half-life data is published by the U.S. Table of Isotopes and [IAEA](https://www-nds.iaea.org/relnsd/vcharthtml/VChartHTML.html), ensuring the stable generation of random numbers.

3. **Is Am241 safe?**

   * **Answer**: Am241 is a radioactive substance also used in household smoke detectors. The GNA Quantum Chip is designed to use a minimal amount of Am241, ensuring safe usage. Alpha particles can be shielded by a single sheet of paper, and within silicon, they only travel about 17 μm. Therefore, they cannot reach outside the chip, and external particles cannot penetrate the chip. This effective shielding ensures no impact on the human body and no radiation leakage to the outside.

4. **What is quantum cryptographic communication?**

   * Answer: Quantum cryptographic communication is a technology that uses quantum phenomena during communication to detect unauthorized access and discard the communication. However, the GNA quantum chip does not perform quantum encrypted communication, but uses this quantum phenomenon called atomic collapse to generate true random numbers and use them for authentication required for encrypted communication. Authentication is always required for quantum cryptographic communication. We can completely protect this place.

5. **What are the applications of the GNA Quantum Chip?**

   * **Answer**: The GNA Quantum Chip can be used in various situations, including online banking, cryptocurrency wallets, remittances, online payments, social media, and data server login authentication.

6. **What is the difference between existing random number generators and the GNA Quantum Chip?**

   * **Answer**: Typical random number generators produce pseudo-random numbers, while the GNA Quantum Chip generates completely unpredictable true random numbers. These random numbers cannot be analyzed even by quantum computers.

7. **How does the GNA Quantum Chip ensure security?**

   * **Answer**: The GNA Quantum Chip generates true random numbers, which are used in authentication and cryptographic communication to prevent hacking and unauthorized access. Additionally, the random number generator embedded within the chip is tamper-proof, and in the event of device loss or theft, ID recovery can be safely conducted using vein fingerprint authentication.

8. **How is the GNA Quantum Chip expected to be marketed?**

   * **Answer**: The GNA Quantum Chip is mainly applicable for authentication and is expected to be marketed to digital-native individuals, financial institutions (for digital currency solutions), insurance companies, and other such targets. Initial sales will be conducted in Japan, with several hundred million units expected to be sold.

9. **What is a quantum random number?**

   * **Answer**: A quantum random number is a true random number generated based on the principles of quantum mechanics. The GNA Quantum Chip detects alpha particles to generate these random numbers, which are then used for authentication and encryption.

10. **How does the GNA Quantum Chip contribute to blockchain technology?**
    * **Answer**: The true random numbers generated by the GNA Quantum Chip are believed to prevent unauthorized logins and authentication by providing a unique sequence of random numbers in blockchain applications. Further technological developments are expected to bring this technology into practical use.
