Oratomic

Oratomic is a quantum computing company developing fault-tolerant, utility-scale quantum computers based on neutral atoms held in place by finely focused laser beams acting as optical tweezers. The company states that a new regime of ultra-efficient quantum error correction, using only light and atoms, makes practical fault tolerance achievable, and it is building both the hardware and software layers of such a system. Its stated goal is to deliver a utility-scale quantum computer by the end of the decade, targeting applications in quantum simulation, chemistry, materials science, physics, machine learning and artificial intelligence.

The company's technical thesis rests on research conducted with scientists at the California Institute of Technology, published as a preprint (arXiv:2603.28627), which argues that utility-scale fault-tolerant machines may require on the order of 10,000 to 20,000 reconfigurable atomic qubits rather than the millions previously estimated. The approach uses reconfigurable arrays of atomic qubits that can be dynamically rearranged during computation to provide more flexible connectivity and more efficient error correction. Oratomic notes that such a machine would be capable of running Shor's algorithm and therefore of breaking widely deployed public-key cryptography, and it points to global guidance to migrate to post-quantum encryption by 2035.

Oratomic is headquartered in Pasadena, California, and is led by co-founder and CEO Dolev Bluvstein. Its team combines expertise in quantum error correction, neutral-atom systems, artificial intelligence and optical engineering, with members drawn from Caltech, UC Berkeley, Harvard, Amazon and Google.

Founding story

According to the company, its founding team previously believed commercially useful quantum computing was far off. A research breakthrough on the resource requirements for fault-tolerant quantum computing, developed with Caltech scientists, changed that view simultaneously for the group and prompted them to form a company. CEO Dolev Bluvstein has said no one on the team could previously have been convinced to start a quantum computing company. Contributors include John Preskill, who has worked on fault-tolerant quantum computing for decades, and Manuel Endres, who has worked on neutral-atom tweezer systems for over a decade.

Business model

Oratomic develops both hardware and software for large-scale fault-tolerant quantum computers. Sources indicate it does not plan to develop or sell noisy intermediate-scale quantum (NISQ) prototype systems, unlike many peers, and is instead focused on reaching a commercially useful fault-tolerant machine; no pricing or commercial offering is described in the sources.

Traction

Oratomic emerged from stealth in 2026 with a research preprint developed with Caltech scientists, then raised a $300 million Series A announced 7 July 2026 co-led by ARCH Venture Partners, Spark Capital and Khosla Ventures. It has also announced a quantum computing partnership with Monarch Quantum and is recruiting to expand its physics and hardware engineering teams. A directory listing associated with coverage of the round places headcount at 11-50 employees.

Latest developments

In July 2026 Oratomic announced a $300 million Series A co-led by ARCH Venture Partners, Spark Capital and Khosla Ventures, with participation from Bezos Expeditions, Index Ventures, General Catalyst, Lowercarbon Capital, Bain Capital Ventures, Formation 8, Nebular, David and Scott Aaronson and others. Proceeds are earmarked for high-performance quantum hardware fabrication, algorithmic R&D on fault-tolerant logical qubit topologies, and expansion of physics and hardware engineering teams. The same month it announced a partnership with Monarch Quantum.
