What is AtomQ?
AtomQ is a deep-tech startup based in Knoxville, Tennessee, positioning itself as the world's first "Quantum Foundry." Unlike neutral-atom quantum computing companies that trap atoms in vacuum chambers with lasers, AtomQ engineers matter atom-by-atom directly inside solid-state crystals using ultra-precise electron beams. This approach creates stable, air-stable atomic configurations that can be manufactured at scale thousands of identical quantum structures in minutes enabling production of qubits, sensors, and quantum light sources outside laboratory conditions.

Technology Explained: How AtomQ Works
The Quantum Foundry Concept
AtomQ's platform addresses a fundamental bottleneck in quantum hardware: most quantum devices require atoms to be positioned with sub-nanometer precision, but existing methods (laser tweezers, ion traps, STM tips) are slow, expensive, and produce fragile structures that degrade outside vacuum chambers.
AtomQ's breakthrough: Using a modified electron microscope (Bruker/Nion platform at ORNL), the company steers individual atoms within a crystal lattice specifically the magnetic semiconductor chromium sulfide bromide (CrSBr) into predefined interstitial sites. This creates vacancy-interstitial defect complexes that form an artificial "mesoscale crystal" embedded in the host material.
Key Technical Capabilities
Precision: Sub-20-picometer beam positioning accuracy
Throughput: 40,000+ user-defined defects created in minutes across 150 nm × 100 nm × 13 nm volumes
Stability: Engineered structures remain stable at room temperature and in ambient air no vacuum requiredpubmed.
Scalability: Platform is generalizable to other 2D/3D materials for deterministic color centers, quantum simulators, and atomic-scale manufacturing
Why This Matters for Quantum Computing
Neutral-atom quantum computers (like Atom Computing, Infleqtion, QuEra) must continuously trap and cool atoms in vacuum, limiting portability and increasing operational complexity. AtomQ's solid-state approach could enable:
Mass-producible qubit arrays with identical atomic configurations
Integration with existing semiconductor fabrication infrastructure
Room-temperature quantum devices for sensing and communications
