Bifrost Electronics, a Colorado-based quantum startup, announced it has successfully raised $2.5 million in seed funding. This investment will accelerate the development of its next-generation quantum amplifiers. The round was led by Caruso Ventures, with participation from Harlow Capital and other investors.
Founded by alumni of the Colorado School of Mines and William & Mary University, Bifrost has pioneered a new class of magnetically insensitive, scalable, electro-optic quantum amplifiers. These amplifiers offer an elegant and functional alternative to traditional quantum readout devices, which are often complex, challenging to use, and prone to failure.
Bifrost has utilized cutting-edge materials science to reimagine quantum amplification completely. Their approach optimizes systems for real-world reliability and scaled integration.
Bifrost’s technology supports a wide array of qubit platforms, including superconducting qubits, spin qubits, and other experimental modalities. Across these applications, Bifrost’s solutions deliver significant improvements in footprint, reliability, noise performance, and cost.
The company’s strategy combines world-class physics and engineering with tailored system integration, ensuring that every amplifier is designed for optimal performance beyond the fabrication lab. Bifrost focuses on developing state-of-the-art systems that are ready to ship, integrate seamlessly into existing stacks, and perform reliably even in extreme conditions.
Bifrost Electronics is currently the only U.S.-based commercial producer of quantum-limited readout components. The company will establish its headquarters at the Elevate Quantum campus outside Boulder, Colorado. This move integrates Bifrost into Colorado’s growing ecosystem of innovators, further solidifying the state’s position as a national hub for quantum technology.
Bifrost is actively collaborating with U.S. industry leaders, including FormFactor, Rigetti Computing, and Maybell Quantum Industries, to tailor systems for commercial deployments. This new funding will support the expansion of Bifrost’s team, scaled manufacturing efforts, and continued partnerships with key stakeholders in the quantum ecosystem.
KEY QUOTES:
“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. 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.”
Zenith Tillemann-Dick, Co-Founder and CEO of Bifrost Electronics
“Unlocking quantum advantage will require bold engineering and new infrastructure built for scale. 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.”
Dan Caruso, Managing Director of Caruso Ventures
“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. 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.”
Zachary Yerushalmi, CEO of Elevate Quantum
