We build new metrology and diagnostic tools for the quantum industry. Our SQUID-on-tip microscope reveals why quantum chips fail, so the industry can make them work.
“The quantitative insights QuantaMap generated can be fed directly into our simulations, helping guide the design of our future chips.”
“Great work & great communication!”
At QuantaMap, we develop cutting-edge tools for metrology and defect inspection of quantum chips and other quantum hardware.
Quantum chips often underperform, and there is no way to find out which component failed. This is a major roadblock for quantum computing.
Our IP-protected SQUID-on-tip microscope pinpoints defects in quantum hardware that no other tool can see.
Our technology will impact the quantum industry and beyond, helping enable the quantum revolution.
A superconducting quantum interference device at the apex of a nanoscale tip: the most sensitive magnetic sensor in existence, scanned across a chip to map currents, dissipation and defects with unprecedented resolution, at cryogenic temperatures, where quantum hardware actually operates.
In a single pass our microscope maps topography, electrical currents, dissipation (heat) and magnetic dipoles: simultaneously, on the same spot, at millikelvin-compatible conditions. These are exactly the quantities that decide whether a quantum device works.
This is not a concept: our microscope is up and running, producing data on quantum chips and quantum materials.

We image superconducting quantum circuits as they operate: topography, static field and AC field maps of the same structure reveal where currents flow and where devices deviate from design.

We map supercurrent flow in novel quantum materials at the nanoscale, resolving current channels and local superconducting properties that no transport measurement can see.

Scalable test and measurement for superconducting quantum chips.
Recognition and backing from the European Innovation Council's flagship programme.
Published results showcasing what our SQUID-on-tip microscope can do.
Early funding to solve a major roadblock in the quantum revolution.
We currently have the following internship projects available (university or HBO), and we're happy to host interns and BSc/MSc students on many other technical and non-technical topics.
Develop an automated sample exchange system operating at cryogenic conditions.
Design and build a reliable automated sample exchange mechanism that operates at cryogenic temperatures (down to 4 K). You will work on mechanical design, prototype testing, and integration with our scanning probe microscope — a direct contribution to reducing measurement turnaround time for our customers.
Apply →Design and implement a scalable database system for our scan data.
We generate rich multi-channel scan datasets and need a robust, queryable storage layer to support data analysis and customer workflows. You will architect and implement a database solution — schema design, ingestion pipelines, and a query interface — from the ground up.
Apply →Develop a scalable IT infrastructure for our company.
We are building the internal backbone — networking, device management, security, cloud services — for a fast-growing hardware and software company. You will scope the requirements, select tools, and implement a professional IT infrastructure that scales with us from 15 to 50+ people.
Apply →Investigate scalability of AFM-SOT probe fabrication.
SQUID-on-tip probes are the sensing heart of our microscope. You will investigate the fabrication process, identify bottlenecks that limit yield and reproducibility, and develop protocols to increase throughput — with direct impact on how many systems we can ship.
Apply →Hands-on project to improve the UI/UX of our measurement and analysis software.
Our instrument control and data analysis software is used daily by physicists and engineers. You will conduct user research, identify pain points, and redesign key workflows — then work with our software engineers to implement the improvements in a real product used by customers worldwide.
Apply →We are a young, fast-moving startup with ample opportunity for you to grow. You get to work with world-leading experts in an exciting, innovative field on top of the strategic agendas of the world's most innovative nations. We explicitly welcome applicants from all backgrounds and identities.
