Magnets For Quantum Research
Bias coils, multi-axis Helmholtz systems and high-field solenoids for quantum hardware and research.
Quantum research
Stable, precise magnetic fields for quantum hardware
Qubits and quantum sensors are only as good as the magnetic environment around them. Our experience building magnets for cutting-edge fusion research has prepared us to support the quantum industry with bias coils, multi-axis Helmholtz systems and high-field solenoids that deliver stable, uniform and well-characterized fields.
Woodruff’s high-precision multi-axis Helmholtz coils are custom-built for your application, supporting approaches from spin qubits and NV centers to Majorana-based topological, magnonic and superconducting qubits. Our high-temperature superconducting (HTS) solenoids provide the strong fields needed in cryogenic research, and our designs offer some of the most consistent field uniformity and strength in the business.
Applications
Fields for every qubit platform
Trapped ions and neutral atoms
Quantization-axis bias fields, Zeeman shifting and field nulling around vacuum cells, with 3-axis coil sets designed around your chamber and optical access.
Spin qubits and NV centers
Uniform vector fields for spin control, ODMR and magnetometry, with independent per-axis control and rotating field synthesis.
Superconducting and topological qubits
Field cancellation and bias for cryogenic platforms, and high-field HTS solenoids for cryogenic research.
Quantum sensors and magnetometers
Calibration coils and Helmholtz systems for characterizing and calibrating quantum magnetometers and atomic sensors.
What matters in quantum
Engineered for field quality
- Field uniformity specified over your working volume, with options from better than 0.5% to 2%
- Low-ripple, precisely regulated matched power supplies
- Multi-axis vector control in Cartesian or polar coordinates
- Non-magnetic materials and designs that work around optical access, vacuum chambers and cryostats
- Electromagnetic and thermal modelling and field maps before anything is built
- From compact bench-top coils to 3-axis magnet sets with high-field solenoids
