Atomic engineering

Write structure. Design function.

AtomQ converts the scanning transmission electron microscope from a tool that observes atoms into an engine that can address, move and organize them inside crystalline materials.

A closed fabrication loop

Control begins with knowing exactly where the beam is.

Atomic fabrication requires more than a small electron probe. AtomQ’s approach combines fast lattice registration, precise beam positioning and programmable exposure paths. The system continuously relates the commanded pattern to the crystal itself, allowing repeated interactions at selected atomic sites.

The method can drive directional atomic rearrangements—not simply remove material—so the resulting vacancy–interstitial structures are embedded within the host crystal.

The workflow

From coordinate map to engineered lattice.

01

Locate

Measure the local lattice and establish a coordinate system with the minimum imaging dose needed for reliable targeting.

02

Register

Align a user-defined design to the atomic structure rather than relying on the microscope’s nominal scan position alone.

03

Act

Execute controlled beam trajectories and dwell sequences at selected sites to drive specific atomic transformations.

04

Verify and scale

Measure the resulting structures, refine the recipe and repeat the process across thousands of sites and multiple layers.

What changes

Defects stop being fabrication noise.

Conventional defect formation commonly produces distributions of positions, orientations and local environments. Deterministic atomic engineering makes those variables part of the design space.

The long-term objective is not merely to place isolated defects, but to manufacture interacting atomic architectures whose optical, electronic and magnetic behavior follows from their arrangement.

Application pathways

One engine. Multiple quantum architectures.

Atomic precision becomes a new design variable across sensing, light, communications, simulation and information processing. Hover over a pathway—or tap it on mobile—for a quick primer and one neutral external reference.

Sensing

Quantum sensing

Position optically or electrically addressable defect centers near the region being measured, with controlled spacing and orientation.

What this means

Quantum sensors use controlled quantum states to detect quantities such as magnetic and electric fields, motion, temperature or time with unusually high sensitivity.

Light

Quantum emitters

Create candidate emitter sites at predetermined locations for alignment with optical collection structures and photonic cavities.

What this means

A quantum emitter can generate light one photon at a time. Precise placement helps align the emitter with cavities, waveguides and collection optics.

Networks

Quantum communication

Develop repeatable emitter–photon interfaces for on-chip routing, entanglement distribution and future network nodes.

What this means

Quantum networks move quantum states between nodes, typically using photons, and require reliable sources, detectors, memories and interfaces.

Many-body physics

Quantum simulation

Arrange interacting impurity states into user-defined lattices to explore collective behavior and model Hamiltonians in solid-state matter.

What this means

A quantum simulator uses one controllable quantum system to reproduce the behavior of another system that can be difficult to calculate classically.

Information

Quantum computing

Pursue scalable arrays of defect-based quantum elements whose positions are defined by fabrication rather than statistical yield.

What this means

Quantum computers encode and process information in quantum states. Repeatable, addressable physical elements are one route toward scaling qubit hardware.

Materials

Atomic-scale electronics

Explore dense memory, logic and functional materials whose electronic or magnetic response is encoded by defect architecture.

What this means

Individual defects can alter conductivity, optical response and magnetism. Deliberately placing them makes atomic-scale structure an electronic design variable.

The integration bridge

Atomic placement is only the first layer of the device.

Usable quantum hardware also requires optical or electrical readout, control, packaging and a material whose engineered states have the right coherence and stability. The critical bridge is registration: every atomic coordinate must map to a repeated, designated active-area coordinate in the photonic or electrical device.

AtomQ’s role is to make that atomic architecture reproducible and alignable across arrays of identical nanophotonic cells—placing each engineered region beside the same resonator geometry, waveguide, grating coupler or electrode interface.

Conceptual pathway: engineered crystal → registered device array → optical or electrical control → quantum system.

Scientific discipline matters

Opportunity without overclaiming.

The atomic-engineering capability is demonstrated. Specific device performance still depends on the defect, host material and readout architecture. AtomQ works with partners to identify which material–application combinations have a defensible route from atomic structure to measurable function.
