The company uses optical tweezers (lasers) to hold individual atoms as qubits and claims a breakthrough in error correction that reduces the qubit count needed for a fault-tolerant, utility-scale quantum computer to just 10,000–20,000 — far fewer than competitors. Unlike most quantum startups, Oratomic is skipping the NISQ prototype stage entirely and aims to deliver a commercially viable quantum computer by the end of the decade. Khosla Ventures called it their largest initial investment to date. ## Full article daily.dev links to this article rather than hosting it.
