Delft and Amsterdam, 11 December 2020 - IMPAQT consortium creates interfaces between Dutch quantum computer startups.

Traditionally Quantum Computer development has been done with a monolithic approach – one entity manufacturing and sourcing all components. This is costly, time-consuming and risky. In order to accelerate Quantum Computer development, IMPAQT envisions a modular approach: Independent companies focus on different parts of the stack.

On the 11th of December 2020, members of the IMPAQT consortium signed an agreement to collaborate on ensuring that different building blocks of QC are interfaced well. In the future, this will allow Quantum Computer manufacturers to easily integrate subsystems.

The members of the IMPAQT consortium are:
- Orange QS - Integrated quantum system provider
- Qblox - Quantum control stack provider
- Delft Circuits - Cryogenic i/o quantum hardware provider
- Qu & Co - Algorithms for industry-relevant quantum advantage

Within the IMPAQT consortium, the members work together to build well-interfaced building blocks of a quantum computer.

August 13, 2020 - Today, Amazon Web Services, Inc. (AWS), an company, announced the general availability of Amazon Brake and the addition of Qu&Co as a partner of the Quantum Solutions Lab

Amazon Braket is a fully managed AWS service that provides a development environment to help customers explore and design quantum algorithms. Customers can use Amazon Braket to test and troubleshoot quantum algorithms on simulated quantum computers running on computing resources in AWS to help them verify their implementation or to run their quantum algorithms on their choice of quantum processors based on different technologies, including systems from Rigetti, IonQ and D-Wave. Both simulated and quantum hardware jobs are managed through a unified development experience, and customers pay only for the compute resources used. 

As of today Qu&Co is a partner of the Amazon Quantum Solutions Lab (QSL) and we use Amazon Braket as part of our quantum software development programs. Amazon QSL engagements are collaborative research programs that allow Amazon’s corporate clients to work with leading experts in quantum computing, machine learning, and high-performance to identify quantum use-cases and implement novel quantum-algorithms. 

Qu & Co supports organization's in-house discovery and optimization activities by developing novel quantum-computational chemistry methods and integrating those with customers’ existing computational-chemistry and material-science workflows. “We are focused on delivering practical quantum-computational approaches for our clients’ most challenging computational workflows,” said Benno Broer, CEO of Qu&Co. “For this purpose, we evaluated different quantum software development platforms. Our experience developing our novel algorithms for quantum machine learning and computational chemistry with the new Amazon Braket service has been very positive. Amazon Braket promises a solid integration between classical and quantum hardware, and gives us a hardware-agnostic development environment, classical simulators, and access to different quantum computers. From that same AWS cloud environment, we can apply tools such as Amazon SageMaker to innovate on behalf of our customers.”

New York and Amsterdam, 3 September 2019 - Schrödinger and Qu&Co today announced a business and scientific collaboration to advance the use of quantum mechanics on complex molecular systems using quantum computing hardware.

Quantum mechanical simulations have become a powerful tool to accelerate materials science and design, but executing the same computations on quantum computers so far remains at an early stage of development. By bringing together Qu&Co’s expertise in quantum computing and Schrödinger’s deep knowledge and experience in applying quantum mechanics in real-world applications, the collaboration aims to advance the state of the art of quantum computing for quantum chemistry. The collaboration will also explore a hybrid computing framework that leverages the strengths of both quantum and conventional approaches to atomistic simulations.

“Quantum computing has the potential to revolutionize our ability to solve important problems in materials sciences,” said Mathew D. Halls, Vice President of Materials Science at Schrödinger. “We’re particularly pleased to be working with Qu&Co, which is strongly committed to advancing the field with the highest degree of scientific integrity. We look forward to learning from one another as we expand the real-world utility of quantum chemistry.” 

“We are committed to developing concrete, pragmatic solutions that demonstrate the utility of quantum computing for quantum chemistry, and we’re delighted to partner with a team that shares this goal,” said Benno Broer, Chief Executive Officer and Co-Founder of Qu&Co. “Together, we believe we can prove — and then improve — the value of quantum mechanics to solve challenging chemical problems for materials scientists across many industries.”

Amsterdam, 31 Juli 2019 - Today Qu & Co, a quantum-computing software developer, announces the release of its first open-source Qu & Co quantum-code.

Qu & Co quantum-codes are a collection of open-source quantum-algorithm libraries, which can be run either on a quantum-simulator or a quantum-processor. Our quantum-codes provide some insight in how we translate academic research in the field of quantum-information into practical applications. Qu & Co quantum-codes are also an invitation to the quantum-community to share knowledge and work together on advancing the development and adoption of industry-relevant quantum-applications.

Qu & Co quantum-codes are open-source and offer only a small insight into the range of algorithms we develop for our corporate clients. If you are interested to learn more about our solutions for chemistry, material-science, life-sciences or quantum-AI, please contact us at This email address is being protected from spambots.

Qu & Co quantum-code-chemistry is an end-to-end stack, which compiles and executes quantum-chemistry algorithms for current-day (small and noisy) quantum-processors. The package is highly customizable and can be executed on a wide range of simulation backend types, in addition to being able to run on Rigetti Computing’s QPU. Users may configure their own quantum-circuits, or use built-in functionality, which allows the user to turn the outcome from various classical computational-chemistry packages into the starting point for creating their own problem-specific quantum-algorithm. For more information please visit 

Qu & Co quantum-code-chemistry implements the so-called Variational Quantum Eigensolver (VQE), which is a quantum-computing algorithm well suited for working with the limitations of current-day small and noisy quantum-processors, because it shortens the necessary quantum-circuits by applying a quantum-classical hybrid optimization scheme. Our quantum-code-chemistry is highly flexible, allowing the user to implement quantum-circuits of their own design or use the built-in unitary coupled-cluster with singles and doubles (UCCSD) method as an Ansatz.

The release of Qu & Co quantum-code-chemistry also marks our first contribution as a QCS Development Partner of quantum-hardware developer Rigetti Computing. QCS serves as a single access point to Rigetti's quantum-processors and quantum-simulators. As a QCS Development Partner, Qu & Co uses the QCS platform for developing quantum-applications and to distribute them to our clients and to the broader QCS community.
