Quantum computing is an application that requires magnetic shielding. Magnetic interferences like building noise, elevators, vacuum pumps, and other nearby electromagnetic fields can cause decoherence in qubits, which can lead to loss of information. Magnetic Shield Corporation can design, simulate, and manufacture magnetic shields for quantum applications. We work with both room temperature shielding materials like our high permeability MuMETAL® alloy and cryogenic temperature shielding materials like our Cryo-NETIC® alloy. Most importantly we use our Perfection Annealing process as a final step to maximize the permeability at the operation temperature.
Warm, room temperature shielding can be added around exterior of the Outer Vacuum Chamber (OVC) of dilution refrigerators. We have design experience to meet the end users requirements and make assembly efficient and repeatable. Single shell or multi-shell shields are used to suppress the ambient magnetic noise. MuMETAL® can also be used in the packaging of quantum chips to prevent and disruption to the circuitry.
Cold, cryogenic temperature shields can be incorporated around superconducting quantum processors, which operate in the millikelvin range. This low frequency shielding material can be used with superconducting RF shields to suppress a larger spectrum of magnetic noise.
MuMETAL® and Cryo-NETIC® can become saturated by strong magnetic fields from power lines and magnets. Where stronger fields are present, our low permeability NETIC® alloy can be added so that MuMETAL® does not become saturated. The NETIC® shield should be placed between the MuMETAL® shield and the source field.
