The company is developing fault-tolerant, utility-scale quantum computers using neutral-atom qubit technology. Its research, conducted with Caltech scientists, suggests that useful quantum computers may require only around 10,000 reconfigurable neutral-atom qubits rather than the millions previously estimated. Oratomic plans to use the funding to expand hardware fabrication, fault-tolerant architecture research, and engineering teams. The company also warns that a capable fault-tolerant quantum computer could eventually run Shor's algorithm, threatening current public-key encryption systems, underscoring the urgency of transitioning to post-quantum cryptography. ## Full article daily.dev links to this article rather than hosting it.
