QHarbor

What QHarbor does

QHarbor is a Dutch data storage and visualization software platform purpose-built for experimental physics researchers and data-driven scientists, particularly those in quantum computing. Founded in 2023 as a spin-out from TU Delft's QuTech research institute and headquartered at Lorentzweg 1 in Delft, the company addresses fragmented measurement data storage, format fragmentation across QCoDeS, Labber, Quantify, and Core-Tools acquisition frameworks, data loss risk, and weak reproducibility in high-throughput experimental environments. Its platform centers on a REST API backed by PostgreSQL metadata storage and an object store, with data converted to a unified netCDF-4/HDF5 format under FAIR ENOUGH compliance principles.

The product portfolio consists of four integrated components: the QHarbor core platform (API + storage), DataQruiser (a cross-platform desktop application for Windows, macOS, and Linux providing search, visualization, and live plotting), qDrive (a Python package distributed via pip for programmatic data interaction, including do0D/do1D/do2D sweep functions), and a Synchronization Agent that automatically monitors data sources, converts files, and uploads them to the centralized server. Deployment options include on-premises (bare metal or cloud provider such as Azure, AWS, or Google Cloud), private cloud with country-specific data center selection for data sovereignty, and on-rack physical delivery. Institutional SSO integration (including EntraID) and scope-level permission management address institutional security requirements.

QHarbor monetizes through quote-based software subscriptions tied to deployment type and user count, supplemented by professional services and consultancy from team members with experimental physics backgrounds. The company pursues a hybrid go-to-market combining direct enterprise sales to research institutions with product-led growth via its open-source Python package and GitHub presence. In May 2026, QHarbor was acquired by Israeli quantum computing company Quantum Machines, after which it operates as part of QM's European software operations with an R&D and collaboration hub in Delft.

Core offering

QHarbor is a data storage and visualization software platform for physics researchers and data-driven scientists, providing a secure, structured repository for measurement data. It consists of the DataQruiser desktop application for visualization, the qDrive Python package for programmatic data interaction, and a synchronization agent that automatically monitors and converts data from measurement frameworks (QCoDeS, Labber, Quantify, Core-Tools) into a unified netCDF-4/HDF5 format. The platform is deployed on-premises, in private cloud, or on-rack to meet institutional data sovereignty requirements.

Product overview

QHarbor is a data storage and visualization software platform designed for physics researchers and data-driven scientists, particularly those in quantum computing and experimental physics. The product portfolio consists of the QHarbor platform (core data repository with REST API), DataQruiser (desktop GUI application for visualization, search, and data organization), qDrive (Python package for programmatic data interaction), and the Synchronization Agent (automated data ingestion from measurement frameworks and folder sources). The platform is designed to be data-acquisition-software agnostic, automatically converting data from QCoDeS, Labber, Quantify, and Core-Tools into a unified netCDF-4/HDF5 format. Deployment options include on-premises (bare metal or cloud provider), private cloud, and on-rack delivery. The architecture supports FAIR data principles with structured metadata organization via scopes, datasets, and files.
