Photonic layer
Light is routed to a registered active area. Waveguides, resonators and couplers bring optical control to the material.
The quantum foundry
We build quantum chips. Atom by atom.
AtomQ is building the atomic engineering engine: technology that turns atomic defects from random imperfections into designed, repeatable building blocks inside solid-state materials.
Deterministic atomic engineering in three-dimensional crystals
Interactive atomic-control model
The engine
Matter becomes programmable.
AtomQ directs a focused electron beam with picometer-scale control, using the microscope as a fabrication instrument rather than only an imaging tool. A target pattern becomes an ordered arrangement of atomic defects written into a crystal.

Atomic active area
Geometry becomes part of the Hamiltonian. Defect placement sets the positions and interaction pathways of the engineered states.
Control & readout
Light in. Quantum state out. A registered optical interface connects the atomic architecture to the outside world.

Custom matter
Not just periodic defects. Any addressable pattern.
A repeated lattice is one powerful architecture, but it is not the limit. Once individual sites become programmable, the pattern can encode letters, symbols, gradients, interfaces, isolated sites or deliberately aperiodic structures.
The scientific opportunity is to control not only defect density, but the exact geometry and local environment of each atomic building block.
Why it matters
The defect can become the device.
At the atomic scale, a missing or displaced atom can change how a material emits light, stores information, responds to a magnetic field or interacts with nearby defects. Today those sites are often created statistically. AtomQ’s goal is to place them deliberately—where device designers need them and in the arrangements that give them function.
That precision creates a new fabrication layer for quantum sensing, light generation and networking, many-body simulation, and future information technologies.
