Quantum computer generates strings of certifiably random numbers
- A quantum computer has been used for the first time to generate strings of certifiably random numbers, with potential applications in various fields.
- Classical computers can only generate pseudorandom numbers, while quantum computers excel at producing genuinely random numbers due to the inherent randomness in quantum mechanics.
- This breakthrough opens up possibilities for applications in fields like lotteries and cryptography.
- Certifying the randomness of the numbers generated by a quantum computer involves cross-entropy benchmarking to verify their quantum origin.
- The study used a 56-qubit high-fidelity Quantum H2-1 quantum computer for generating random numbers and exploring quantum magnetism and knot theory problems.
- Verifying the authenticity of random numbers from quantum computers can be computationally intensive, requiring further research for more efficient methods.
- The research advances the understanding and application of quantum computing in solving complex problems with real-world implications.
- Quantum computing's value is now assessed based on the problems it can solve rather than just the technical specifications of the hardware.
- The potential for quantum computers to tackle larger models and expand their capabilities is evident in the development of a 96-qubit device named Helios.
- The research showcases the shift in focus from the hardware capabilities of quantum computers to the practical problems they can address effectively.
