Environmental analysis and site planning for quantum computing magnet systems
Scientific Magnetics has more than 30 years of experience in environmental analysis and site planning for superconducting magnet systems. This expertise directly supports the unique and complex needs of quantum computing qubit architectures.
The environmental sensitivities that affect qubit coherence and noise performance include:
- Micro-tesla variations in background magnetic field
- Micro-g levels of mechanical vibration
- The influence of structural steel reinforcement
within buildings - The effects of moving vehicles and large ferrous objects
in the vicinity of the installation
These are the same challenges Scientific Magnetics has characterised and mitigated for high-field superconducting magnet systems across a range of demanding scientific and medical applications throughout our history.
Using the same proven measurement methodologies and advanced instrumentation applied to some of the world’s most sensitive magnet installations, Scientific Magnetics provides a comprehensive site assessment and environmental characterisation service for quantum computing projects.
