Navigation
A live magnetic reading matched against a survey map provides a position fix when GPS is jammed or unavailable.
Technology
Vapour cells have been blown by hand, one tube at a time. We fabricate them by the hundreds on a wafer.
| Glass blown | Wafer printed | |
|---|---|---|
| Made | One at a time | 430 per wafer |
| Shape | Tube, centimetres | Square, millimetres |
| Optical access | One direction | All directions |
| Match | Every cell differs | Every cell identical |
How it senses
Polarised light aligns the atoms, the magnetic field sets them precessing, and a probe beam reads the result.
Why wafer-scale
Wafer-scale fabrication produces vapour cells in volume, with consistent quality from cell to cell.

Built on wafer to reduce cost and remove other bottlenecks, making quantum sensing accessible.
Every cell is patterned in the same process step, so each one matches the next.
A transparent core holds the alkali vapour between a cap wafer and a base substrate.
Pump and probe beams cross inside the cell from several directions, improving sensitivity and versatility.
Why multiaxial
One short optical path. Simple to fabricate, limited in sensitivity.
A longer path improves sensitivity. The beams still travel in one direction.
Beams cross from several directions. No commercial product offers this today.

Sensing on land, at sea and in the air, with no emissions to detect and no signal to jam.
Open in Learn →Brain and heart imaging with compact, wearable sensors instead of a helium cooled system.
Soil and subsurface water mapped from a drone or a tractor.
News
Q.InC is partnering with the Quantum Sensing Centre, managed by DSO National Laboratories, to develop wafer-scale vapour cells in Singapore, a step toward local industrial capability in a critical quantum component and more resilient Positioning, Navigation and Timing (PNT).
Through wafer-scale manufacturing, Q.InC is addressing the challenge that has kept quantum technologies in the lab: manufacturability. Leveraging advanced semiconductor processes, wafer-scale vapour cells enable:
From shipping and aviation to power grids, financial infrastructure and defence, accurate positioning and timing underpin systems relied on every day. As dependence on satellite-based navigation grows, technologies that keep working when GPS is limited, disrupted or unreliable matter more each year.
Quantum sensors, including magnetometers, atomic clocks and gyroscopes, open new ground on precision, stability and performance. At the core of many of them sits the vapour cell, the component enabling high-performance sensing.
Beyond resilient PNT, this technology platform has potential applications across defence, healthcare and precision agriculture. Upon completion of the project with DSO, Q.InC’s wafer-scale vapour cell programme will be commercialised through a dedicated venture spin-out, bringing Singapore-made quantum hardware to market.
“The next breakthrough in quantum sensing will be focused on improving the yield and economics of devices. Making cells by the hundreds, identically, on one wafer is the real unsolved problem, one that we uniquely address using advanced semiconductor processes.”Dr Leo Krivitskiy, Senior Principal Scientist, Q.InC
“Resilient PNT stops being a line in a strategy paper the moment you can't source the hardware to deliver it. Building that capability locally, before you urgently need it, is the entire point.”Eric W. Cao, Entrepreneur Partner, Q.InC
“The Quantum Sensing Centre is excited to be partnering with Q.InC on wafer-scale vapour cell fabrication. This is a significant step towards building industrial capability in a critical quantum component.”Cheng Kok Ping, Executive Director, Quantum Sensing Centre
This milestone reflects Q.InC’s broader mission to translate foundational quantum research into real-world applications and support the growth of Singapore’s quantum technology ecosystem. Through collaborations across research and industry, Q.InC continues to advance capabilities that bridge scientific innovation and deployable quantum technologies.
