BOULDER, Colo., July 15, 2025 /PRNewswire/ — Today, Bifrost Electronics, a Colorado-based quantum startup, announced it has raised $2.5 million in seed funding to accelerate development of its next-generation quantum amplifiers. Led by Colorado’s Caruso Ventures, investors include Harlow Capital and others.

Founded by alumni of the Colorado School of Mines and William & Mary University in Virginia, Bifrost has developed a new class of magnetically insensitive, scalable, electro-optic quantum amplifiers. Traditional quantum readout devices are notoriously complex, difficult to use, and failure-prone; Bifrost offers an elegant, functional alternative.

The company has pioneered the application of cutting-edge materials science to totally reimagine quantum amplification, optimizing systems for real-world reliability and scaled integration.

Bifrost tech supports a wide range of qubit platforms, ranging from superconducting qubits to spin qubits to other experimental modalities. Across applicable platforms, Bifrost delivers improvements including footprint, reliability, noise performance, and cost.

“Quantum is complicated – its readout devices shouldn’t add complexity for the researchers. By building readout chains that work straight out of the box, Bifrost is helping establish the United States as the undisputed leader in both quantum and its fundamental support infrastructure,” said Zenith Tillemann-Dick, Co-Founder and CEO of Bifrost Electronics. “We’re done accepting fragile hardware as a fact of quantum science. Bifrost is engineering systems that scale quickly, integrate cleanly, and effectively serve real customers by solving real problems.”

“Unlocking quantum advantage will require bold engineering and new infrastructure built for scale,” said Dan Caruso, Managing Director of Caruso Ventures. “Bifrost is pushing the envelope on what quantum hardware can do, tackling one of the toughest technical bottlenecks with urgency and clarity. This is the kind of foundational innovation that moves entire industries forward. We’re proud to back Bifrost and invest in the systems that will make quantum computing real.” Bifrost is the fifth Colorado-based quantum investment by Caruso Ventures.

Bifrost’s approach blends world-class physics and engineering with tailored system integration, ensuring that every amplifier is designed for optimal performance beyond the fabrication lab. Balancing ambition with pragmatism, Bifrost develops state-of-the-art systems designed to ship, integrate seamlessly into existing stacks, and perform reliably – even in the most extreme conditions.

Bifrost is the only U.S.-based commercial producer of quantum-limited readout components. The company will be headquartered at the Elevate Quantum campus outside Boulder, Colorado – joining a growing ecosystem of innovators working to establish Colorado as a national hub for quantum technology.

“The Bifrost leadership team’s commitment to building scalable, reliable, U.S.-made readout solutions underpins a critical part of the value chain in quantum and our nation’s quantum epicenter in the Mountain West,” said Zachary Yerushalmi, CEO of Elevate Quantum. “On behalf of the entire Elevate Quantum community, I’m proud to support Bifrost on this next phase of growth, and look forward to working alongside the team at our new Quantum Commons campus.”

Bifrost is actively collaborating with U.S. industry leaders like Form Factor, Rigetti Computing, and Maybell Quantum Industries to tailor systems for commercial deployments. This funding round will support team expansion, scaled manufacturing, and continued partnerships with key ecosystem stakeholders.
