01
What is a single-photon emitter?
A nanoscale light source that releases one photon at a time. Those photons can carry quantum information or probe their environment in sensing systems.
TECHNOLOGY
hBN materials and device technologies
Photon Foundry is developing hBN materials and technologies for quantum photonics and semiconductor device stacks. Our work builds on hBN growth, defect engineering and characterisation, with research-grade single-photon emitters available today.
DEVELOPMENT DIRECTION
hBN for semiconductor device stacks
We are developing hBN materials for applications across semiconductor device stacks, including future 2D electronics. This direction builds on our materials development and characterisation capabilities.
Quantum photonics
Quantum photonics in six answers
Photon Foundry is translating room-temperature quantum emission in hBN into repeatable, integrated sources designed for use beyond specialist laboratories. Longer-term product paths include packaged sources, sensing, QKD and QRNG hardware, education products, photonic integration and supporting software.
02
Why is the source a bottleneck?
A deployable source must be stable, repeatable and easy to integrate. Sources requiring cryogenic cooling, fragile alignment or device-specific calibration add complexity to the systems built around them.
03
Why is hBN relevant?
hBN can host single-photon emitters operating at room temperature at wavelengths spanning the UV to NIR range. Its layered form factor creates promising routes to compact photonic integration.
04
What can Photon Foundry do today?
Photon Foundry can grow hBN; create, locate, map and characterise research-grade emitters; and fabricate monolithic and hybrid emitter-coupled photonic nanostructures.
05
What applications have been demonstrated?
The founding team has demonstrated proof-of-concept quantum key distribution, quantum random-number generation, quantum sensing and super-resolution imaging.
06
What still needs to be engineered?
The remaining work is product engineering: improve repeatability and process control, stabilise optical interfaces, package sources for use outside specialist laboratories, and establish scalable integration processes.

QUANTUM PHOTONICS
From emitter to engineered source
Our workflow connects materials growth and emitter selection with nanophotonic integration and packaging. Each stage generates evidence for the next.
- Current capability
Create and characterise
Optically active defects in hBN create quantum emission. Photon Foundry grows hBN, creates and locates emitters, measures their optical behaviour and selects research-grade sources for defined uses.
- Demonstrated capability
Couple to photonic structures
Selected emitters can be coupled to monolithic hBN or hybrid photonic and plasmonic structures that control, collect or route their light.
- Productisation
Package and integrate
A deployable source needs stable optical alignment, repeatable interfaces and packaging that works outside a specialist emitter laboratory. These are the current productisation priorities.
Research to product
Published science is the foundation; repeatable hardware is the product
Peer-reviewed publications establish the scientific foundation for hBN quantum emission, defect engineering and photonic integration; they do not establish a finished product. We are converting the foundation into repeatable processes, engineered interfaces and packaged sources.
