Quantum computing harnesses superconducting and semiconducting qubits to complete calculations faster. Lasers and electromagnetic fields can control these qubits, or quantum bits, within vacuum chambers, changing their energy states and powering robust computing capabilities. As the ability to fine-tune electromagnetic fields within qubit architectures becomes more refined, opportunities for faster and more complex data processing grow.
Custom Coils is leading provider of specialty, precision-engineered electromagnetic coil solutions. We work with organizations throughout the quantum computing sector to develop coils for predictable, consistent outcomes. Learn about the role electromagnets play and how Custom Coils supports this high-tech industry.
How Electromagnets Are Used in Quantum Computing Applications
Electromagnets are used in several ways in quantum computing systems. Trapped-ion and neutral-atom quantum computers rely on electromagnetics to keep atoms contained within vacuum chambers where microwaves can change their quantum states.
Magnetic fields and microwaves also control the movement and activity of superconducting and semiconducting qubits. The better and more consistently the electromagnet can generate fields, the more optimal the gate fidelities for microfabricated circuits and electron spins.
Electromagnets may even play a role in helping particular qubits, like nitrogen-valency centers in diamond, communicate through magnons (i.e., converted microwave signals) that can jump micrometer-length distances between qubits to exchange information.
Quantum computers can use fluxgate probes to monitor ambient electromagnetic fields and sense any fluctuation to adjust the currents and provide better stability.
Micro-coils generate strong magnetic fields despite their small size and offer fine-tuned gradients for control. Micro-coils with non-spiral geometries, pulsed operation modes, or radial cuts can even avoid conventional challenges like joule heating or mechanical stress.
Field coils with rare-earth magnets can produce stable quantization fields, and when used with an optimal coil, currents can actively keep the field stable and reduce spatial variations for coherence times that linger more than six seconds.
Incorporating shielding in coils helps to further advance quantum computing capabilities as well. Superconducting coil shields have thin coils that wrap around a lightweight core, and this construction can mitigate magnetic interference by generating opposing fields, significantly increasing qubit life.
How Custom Coils Supports the Quantum Computing Industry
To continue making advances in quantum computing it’s important to partner with an experienced electromagnet provider. Custom Coils has over 45 years of experience developing custom electromagnetics for niche, cutting-edge technologies. Our end-to-end design and development processes include:
Initial concept support
Our design and engineering teams work with customers to understand the parameters and requirements for each electromagnet including core and coil material, power, and size.
Confidentiality
We’re committed to your confidentiality and the sensitive nature of some projects. Our team can create electromagnets solutions and products with only the provided performance specifications, not full application knowledge.
Prototyping
We use CAD and thermal modeling technologies to assess coil designs for performance and manufacturability challenges before developing physical and virtual prototypes for in-depth testing.
In-house manufacturing
Custom Coils conducts all of its manufacturing in-house. We source materials from trusted vendors, create efficient production workflows, and complete assembly.
Quality control
As part of our manufacturing processes, we test the coils for magnetic field strength and stability, inductance, resistance, hipot (i.e., high potential), and thermal behavior. We can test our products for compliance with UL, NEMA, and ISO standards, and we continually monitor our manufacturing processes to find improvement opportunities.
R&D support
We’re committed to helping the quantum computing industry develop. We partner with research institutions on new electromagnetic assemblies, test new technological capabilities, and provide both prototypes and full-production manufacturing capabilities.
Customers can also choose Custom Coils for chokes, electromagnets, focusing magnets and solenoids, inductors, RF coils, and more, including both standard and custom options.
Why Work With Custom Coils for Quantum Computing
Companies across the quantum computing industry trust custom coils for high-performance electromagnetic solutions. We provide comprehensive design, prototype, testing, and production capabilities for coils and other products that drive advances in quantum computing.
In cases where IP, confidentiality, or business security restrict what information can be shared with vendors, our team can still create custom solutions with only the details that apply to our portion of the project.
