Enabling the Future of Quantum Computing

Orange QS accelerates the research on quantum physics and the development of quantum technology for quantum computing.
We support R&D labs with custom characterization and calibration software and develop customized full-stack setups for R&D into quantum computing.
Orange QS is part of Quantum Delft's world-leading ecosystem for innovation in quantum technologies.

What we offer

We offer Accelerator, a line of full-stack setups, that supports quantum computing R&D. Quantify, the control framework used to operate these setups is available as a stand-alone product. We also provide an engineering service for labs that do research into quantum physics and develop quantum computing technology.

Product lines Accelerator and Quantify with relevant services


Quantify is an open-source framework that can be used to control experimental physics research setups and quantum computers. It is based on PycQED and is extended and maintained by Orange QS and Qblox. It provides extensive documentation, tutorials, robust test coverage and centralized maintenance and support.

Quantify Core is the back-bone of the full-stack setups of Orange QS and offers all basic functionality required to control the experiments required for quantum computing. Quantify Scheduler is a module for writing quantum programs. It features a unique hybrid control model allowing quantum gate- and pulse-level descriptions to be combined in a clearly defined and hardware-agnostic way. Quantify-scheduler is designed to allow experimentalists to easily define complex experiments, and produces synchronized pulse schedules to be distributed to control hardware.

Orange QS offers paid extensions to Quantify, for instance custom experiment libraries, tailored to your needs, or custom integration of Quantify with the hardware you have in-house.


The Accelerator product line builds on our expertise on systems integration. It currently contains three products, tailored to your needs.

  • Demonstrator Platform: A tool for testing and validating quantum computing components.

  • Device Development Platform: A tool for characterizing quantum devices, supporting your device manufacturing effort and pilot line.

  • Algorithm Development Platform: A tool for developing quantum algorithms.

Orange QS offers Engineering Support as a service, for designing or sourcing your setup for research into quantum computing. This accelerates your timeline, reduces cost and lets you focus on your research efforts. Next to Engineering Support, we offer Device Characterization as a service.

Garrelt obtained his MSc degree in Physics and his BSc in Dutch Law at the University of Utrecht in 1998. He finished his PDeng in Mechanical Engineering on Computational Mechanics at the Twente University in 2001. In 2007 he became a TNO Project Manager, and was responsible for several product development projects and research programs. From 2009 onwards he took Department Management responsibility for a group of 60 R&D professionals. In 2017 he started as a QuTech Roadmap Leader, responsible for managing the engineering activities.

During his PhD (cum laude) in the group of Prof. DiCarlo, Adriaan worked on control for superconducting quantum systems. He has developed new calibration and characterization protocols, as well as a new type of two-qubit gate, and made key contributions to the development of Quantum Infinity, a transmon-based full-stack quantum computer that preceded QuTech’s Quantum Inspire platform. Adriaan has worked closely with experts from all layers of the stack, which was formally recognized through the Zurich Instruments Pioneer Award, and resulted in award-winning papers. Before starting his PhD, Adriaan was on the executive board of a non-profit business consultancy.

Amber moved from Belgium to the Netherlands in 2011 to study Aerospace Engineering at the TU Delft. He co-founded the automated coating company Qlayers BV in 2017, and the Aerospace Innovation Hub at the TU Delft in 2018. This gives him experience in bootstrapping high-tech companies. Working at TNO since 2019, he analyzed the market of quantum computing and has applied this insight to Orange Quantum Systems as a business developer.

Freeke Heijman - Founder and Director of Quantum Delta Nederland; Director of Quantum Delft

Welcome to the vibrant quantum community in Delft!

We have been waiting to see a systems integrator like Orange QS emerge out of QuTech, TNO and TU Delft. And now it’s here! I’m looking forward to the quantum computing solutions that Orange QS will bring to the market. The team of Orange QS clearly understands the operational issues at play and has access to the best solutions that Delft has been optimizing for years, be it in electronics, software, cryo and hardware. They will offer a valuable service by providing their know-how on integrating setups for quantum computing R&D.

Sal Bosman - CEO of Delft Circuits

Let's build a kilo-qubit NISQ system!

From day one, we have been convinced that a healthy quantum industry naturally evolves into various players in a strong value chain and diverse eco-system. We are very glad that Orange QS joins the campus as an integrator, that shares one of our goals of (contributing to) building kilo-qubit scale NISQ systems. Together with our customers, we make quantum technologies reality, so let’s get it done.

Sal Bosman - CEO of Delft Circuits

Niels Bultink - CEO of Qblox

Looking forward to co-development with Orange QS.

We will work closely together with Orange QS on integration of the quantum computing setup, for example on control software. It’s challenging to set up a quantum computing stack and keep it operational. Great to see a company in the Delft quantum ecosystem taking up this integration challenge.

Niels Bultink - CEO of Qblox

Benno Broer - CEO of Qu & Co

Looking forward to keeping a close alignment between our quantum algorithms and the hardware they have to run on.

At Qu&Co, we build quantum algorithms. We’re excited to see a company emerge out of the Dutch quantum ecosystem that wants to integrate quantum computing systems. We look forward to working together with Orange QS and we will keep a close feedback-loop with teams working on improving quantum hardware.

Benno Broer - CEO of Qu & Co

Lieven Vandersypen - Professor of Quantum Nanoscience & Director of Research at QuTech

The right team to create success.

QuTech is a source of talent and knowledge in the quantum ecosystem that we develop around it. Our mission, scalable prototypes, and our full-stack approach provide a basis for the growing global quantum industry. We trust that the OQS team, with its experience in building quantum systems, will provide unique value to its customers.
