Oratomic, a quantum computing startup founded by Caltech physicists, has raised $300 million in a Series A round to build a practical quantum computer that requires only 10,000 to 20,000 qubits—a significantly lower count than most designs. The company aims to deliver a useful, scalable machine by the end of the decade leveraging a novel laser-based approach.
- Oratomic raised $300M from leading VCs including ARCH Venture and Khosla Ventures.
- Technology uses lasers to hold atoms for quantum bits, enabling error correction with fewer qubits.
- Targets viable fault-tolerant quantum computer with 20,000 qubits by end of this decade.
What happened
Oratomic announced a $300 million Series A funding round co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures. The startup was founded by physicists from Caltech and has developed a unique quantum computing architecture that relies on laser traps to hold individual atoms, which serve as qubits in the machine.
Unlike many competitors focusing on noisy intermediate-scale quantum systems (NISQ), Oratomic plans to skip this stage and build a fully error-corrected quantum computer that needs significantly fewer qubits—between 10,000 and 20,000. The company has already experimentally demonstrated critical components of its system at a smaller scale.
Why it matters
Quantum computers promise to revolutionize industries requiring complex calculations such as biotechnology, materials science, logistics, artificial intelligence, and cryptography. However, current quantum devices struggle with noise and error correction, which limits their practical utility.
Oratomic’s approach could lower the barrier to building scalable and fault-tolerant quantum systems by significantly reducing the qubit count needed for error correction. This breakthrough may enable faster development of commercially viable quantum computers, potentially unlocking new applications and attracting more investment to the quantum ecosystem.
What to watch next
Oratomic’s progress toward demonstrating a fully operational quantum computer with 20,000 qubits will be crucial over the next few years. Investors and industry observers will track its ability to scale its prototype components and deliver a stable, fault-tolerant machine by the decade’s end.
The startup’s strategy differs from competitors like PsiQuantum, which aims for a million-qubit system shortly, making Oratomic’s simpler, less costly design a key point of differentiation. Ongoing funding, experimental validation, and partnerships will likely determine if this approach accelerates the timeline for practical quantum computing breakthroughs.
