Oratomic Raises $300M to Build Quantum Computer Requiring Only 20,000 Qubits

Quantum computing startup Oratomic has raised $300 million in a round co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures. The company aims to build a viable quantum computer that requires only 20,000 qubits — a far lower count than many competing approaches. The round represents one of the largest single investments in the quantum computing sector to date.
