What we do

Diagnostics for the quantum industry

At QuantaMap, we develop cutting-edge tools for metrology and defect inspection of quantum chips and other quantum hardware.

The roadblock for quantum

Quantum chips often underperform, and there is no way to find out which component failed. This is a major roadblock for quantum computing.

Our solution

Our IP-protected SQUID-on-tip microscope pinpoints defects in quantum hardware that no other tool can see.

The impact

Our technology will impact the quantum industry and beyond, helping enable the quantum revolution.

Built on SQUID-on-tip technology

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.

One scan, every channel that matters

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.

It already works

Measuring real devices, today

This is not a concept: our microscope is up and running, producing data on quantum chips and quantum materials.

Quantum chips

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.

Quantum materials

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

We are hiring

Join our growth journey

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.

Mechanical Engineering Internship

Develop an automated sample exchange system operating at cryogenic conditions.

Details →

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 →

Database Internship

Design and implement a scalable database system for our scan data.

Details →

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 →

IT Infrastructure Internship

Develop a scalable IT infrastructure for our company.

Details →

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 →

Research Internship — Probe Fabrication

Investigate scalability of AFM-SOT probe fabrication.

Details →

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 →

UI/UX Internship

Hands-on project to improve the UI/UX of our measurement and analysis software.

Details →

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.
