The Qruise Toolkit

A collection of algorithms – optimizers, simulators, machine learning tools and other software components designed to accelerate the development of quantum technology and to improve its application.

Qruise Toolkit: Quantum device, Characterization, Digital Twin, Optimal Control, Control & Calibration

Characterization — Model Learning — System Identification

You may select any set of experimental data. Then Qruise will utilize a digital twin to simulate these experiments and optimize the model parameters to best match the experimental data. No coding of fitting functions is necessary with this approach, making it possible to determine multiple parameter values simultaneously.

Calibration & Continuous Recalibration

Qruise offers a very wide selection of optimization algorithms that are capable of utilizing any experimental procedure for determining operation fidelity. Our unique ongoing-recalibration capabilities continuously work in the background and keep the operations always at their optimal working point.

Hardware Agnostic Digital Twins

At the heart of the Qruise toolset is a detailed and comprehensive digital twin of your experiment – both the core quantum components and all surrounding experimental equipment. It is a physics-based, white box, Tensorflow simulation, which has been highly optimized for both speed and memory consumption. The digital twin comes with a large library of components and capabilities, and you are free to extend and modify it to best suit your needs. If you require any custom extension that has the potential to be helpful in a variety of setups, we would be thrilled to provide it to you.

Optimal Control

Based on a model, your choice of a control parameterization and goals, Qruise can find the optimal controls to drive the system to the desired state or gate. The optimization can handle many dozens of concurrent parameters, including time-dependent pulse shapes, to allow full utilization of possible controls. Further, one may check the robustness of the resulting pulse to variability in the model, noise in the control pathways and more.

Qiskit Private Quantum Cloud

For quantum computers, Qruise can connect the device to a fully functional Qiskit stack, including circuit scheduling capabilities, allowing you to treat your experimental devices as a private Qiskit quantum computing cloud and aiding collaborative workflows in distributed teams.
