Oratomic, a quantum computing startup founded by Caltech physicists, has raised $300M in a Series A round co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures.
Bezos Expeditions, Index Ventures, General Catalyst, Lowercarbon Capital, Bain Capital, and others also participated. The company is developing a utility-scale quantum computer using an optical tweezer approach that its founders believe requires significantly fewer qubits than competing architectures, with a target of delivering a commercially viable system by the end of the decade.
Addressing The Market Opportunity
The race to build the first commercially viable quantum computer is one of the most consequential technology contests of the current decade. A full-scale quantum computer could accelerate breakthroughs across any field requiring complex calculations, from biotech, chemistry, and logistics to artificial intelligence and cryptography. Investor interest in the sector has surged recently, with several quantum startups going public and existing public companies in the space seeing significant share price appreciation over the past eighteen months.
The central challenge holding the field back is error correction. Quantum computers are highly sensitive to noise, and the ability to correct errors reliably is what separates research instruments from genuinely useful tools.

How The Technology Works
Oratomic uses lasers acting as optical tweezers to hold individual atoms in place as the physical basis for its quantum computing architecture. The key breakthrough that led to the company’s founding was the discovery that this approach can achieve effective error correction using far fewer qubits than previously thought necessary.
While most quantum computing companies are building or selling noisy intermediate-scale quantum systems as stepping stones, Oratomic has deliberately bypassed this stage entirely. The company’s founders believe that utility-scale performance can be reached with between 10,000 and 20,000 qubits, a figure significantly lower than the million-qubit targets of some competing approaches. Oratomic states that it has already experimentally demonstrated all of the core components required for a full-scale computer at a slightly smaller scale, making the path to commercial viability both simpler and less expensive than alternative architectures.
Growth And Market Traction
Oratomic entered the quantum computing race earlier this year. The company was founded by Caltech physicists who had not previously planned to start a quantum computing company, viewing the technology as too distant to be commercially actionable. The error correction discovery changed that assessment and led directly to the company’s formation.
The $300M Series A, described by Khosla Ventures as its largest initial investment to date, reflects the level of conviction the round’s lead investors have in both the approach and the team behind it.
Expansion Plans
The funding will support Oratomic’s work toward building a utility-scale quantum computer by the end of the decade. The company’s strategy is to move directly to fault-tolerant, commercially viable hardware rather than releasing intermediate research systems along the way.
Looking Ahead
Dolev Bluvstein, co-founder and CEO of Oratomic, explained what changed his team’s thinking about entering the quantum computing space: “You would have not previously been able to convince any of us to start a quantum computing company, because we just thought it was way too far away. Only when we made this recent breakthrough did we simultaneously all change our minds.”
On the technical differentiation from competing approaches, Bluvstein was direct: “The difference is that we need roughly 10,000 to 20,000 qubits to build a useful computer, and we have already experimentally demonstrated all of the core components required of that computer at a slightly smaller scale.”
About Oratomic
Oratomic is a quantum computing company founded by Caltech physicists and focused on building the first utility-scale fault-tolerant quantum computer by the end of the decade. The company uses laser-based optical tweezers to hold individual atoms as qubits, an architecture its founders believe enables effective error correction at a scale of 10,000 to 20,000 qubits, significantly fewer than competing approaches require. Oratomic has raised $300M in Series A funding from ARCH Venture Partners, Spark Capital, Khosla Ventures, and others.
