Seamless Database Integration

HQS uses well-defined exchange formats for the problem description and quantum program: struqture and qoqo (respectively), both of which are open-source packages. These formats are connected to various existing backends and can also easily be connected to other formats by the user. For instance, there is a qoqo to QASM backend and a struqture to QuTIP backend. Therefore, this allows for easy connection to transpilers, QPUs and quantum toolkits.

For the definition of both a use case and its corresponding quantum program, HQS uses the JSON format which can be easily stored and shared. This allows not only for an easy integration of all the HQS tools into e.g. a database, but also for smooth collaboration, without the exchange of large python programs.

Perform efficient time evolution of spin systems on a quantum computer, for instance for NMR simulation. Trotterized time evolution is the basis of applications with expected near-term quantum advantage.

Interoperability
(Transpilers, QPUs, Quantum Toolkits)

Enable novel quantum computing paradigms inspired by cooling and open quantum systems, for example approaches like thermal gradient descent for finding minima.

Prebuilt Variational Algorithms
(QAOA, VQE)

Error Mitigation

Starting from a system-bath Hamiltonian, choose either a linear or all-to-all algorithm and generate a quantum circuit with a built-in system-bath mapping.

Add-On

Advanced classical solvers
(for benchmarking)

What is it good for?

Variational algorithms are a great way to get started into quantum computing. However, HQS does not believe that variational algorithms can achieve quantum advantage.

To achieve quantum advantage, comparing to the best possible classical software is crucial. 
See our use case discussion.

Pass a spin hamiltonian (e.g. NMR hamiltonian) to the HQS Qorrelator App and get a QuantumProgram compiled for your device.

Error mitigation features are best provided by the quantum computing hardware manufacturers.

HQStage provides the stage for your quantum simulations. With HQStage you gain access to our powerful quantum simulation modules each with distinct use cases and unique features. HQStage and its modules strictly follow our philosophy to provide easy-to-use yet powerful quantum simulation software tools.

As scientists and developers, we understand your preference for using scientific libraries and tools flexibly in a powerful programming environment. Our HQStage tools can be used individually for specific tasks in simulating quantum systems or combined to create complex workflows.

  • When we design our tools, our focus is on creating clear and intuitive interfaces. This approach not only simplifies the use of each tool on its own, but also ensures they can be easily interconnected for more comprehensive tasks.

    Nonetheless, the inherent complexity associated with scientific software is undeniable. To mitigate this and enhance user experience, we provide the HQS Modeling Assistant. This AI-powered chat assistant simplifies the onboarding and use of our software, making it more accessible and user-friendly.

  • Before starting a simulation, you need to create a detailed description of the system you want to simulate. This description should be as accurate as possible and compatible with the simulation methods you're using.

    With HQS Molecules, we make it easy to turn a molecule's name into a 3D model on your computer.

    Also, our HQS Spin Mapper tool lets you convert an electronic description into a spin-based one. This gives you more options for simulation methods and makes it possible to simulate these systems on quantum computers.

  • Discover the power of quantum simulation with HQS' suite of simulation tools, designed to run on conventional computers.

    Study many-particle physics problems efficiently with the HQS Quantum Solver.

    Calculate spectra of spin systems with HQS Spectrum Tools in the context of NMR spectroscopy.

    Compute properties of materials and devices on a large scale with HQS Qolossal.

    Tackle the complexity of noisy quantum systems with HQS Raqet.

  • Quantum advantage has been shown for abstract problems, but practical benefits are still limited. HQS's approach to quantum computing aims to address this by focusing on time evolutions on quantum computers and managing noise in a unique way.

    The HQS Noise App provides a new way to translate problems from fields like chemistry, materials science, and other quantum mechanical problems to a quantum computer.


    The HQS Qorrelator App is designed to calculate correlation functions, especially for NMR spectroscopy.


    With the HQS Quantum Libraries we offer a wide range of modules for advanced quantum computing tasks.
