We build AI software solutions that enable efficient quantum computing and quantum sensing applications.
Contact usSimphony
Simphony is an open-source Python package for simulating spin dynamics in central spin systems, with a focus on nitrogen-vacancy (NV) centers coupled to nuclear spins. It provides a modular and efficient framework for building quantum registers, designing pulse sequences, and analyzing system dynamics for quantum information and sensing applications.
- Build central spin registers with a focus on NV centers
- Simulate time evolution, compute gate fidelity
- Optimize pulse sequences with autodiff based algorithm
- Further properties
We leverage our academic and industry expertise in physical modeling, quantum information and artificial intelligence for building holistic solutions to
We are proud to be part of the AI4QT research project in which we develop device-specific quantum compiler and error mitigation tools together with our partners: Fraunhofer IAF, XeedQ and Wigner Research Centre for Physics.
