Quantum Amplifiers: Bifrost Raises $2.5M for Scalable Quantum Hardware

Bifrost Electronics, a Colorado-based quantum startup, has secured $2.5 million in seed funding to advance its innovative quantum amplifiers, marking a significant step toward scalable quantum hardware. Led by Caruso Ventures, with contributions from Harlow Capital and other investors, this funding underscores the growing momentum in the U.S. quantum technology sector. Founded by alumni of the Colorado School of Mines and William & Mary University, Bifrost is redefining quantum amplification with a focus on reliability and integration.

Traditional quantum readout devices often suffer from complexity, fragility, and poor scalability, posing significant challenges for researchers and industry applications. In contrast, Bifrost’s electro-optic quantum amplifiers leverage advanced materials science to deliver a robust, magnetically insensitive solution. These amplifiers support a variety of qubit platforms, including superconducting and spin qubits, offering improvements in footprint, noise performance, and cost. For example, their design simplifies integration into existing quantum systems, making them a practical choice for real-world deployments.

"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."

— Zenith Tillemann-Dick, Co-Founder and CEO of Bifrost Electronics

Engineering for Scalability and Reliability

Bifrost’s approach combines cutting-edge physics with precision engineering to create quantum amplifiers that perform reliably under extreme conditions. Unlike traditional solutions, which often require delicate calibration and are prone to failure, Bifrost’s systems are designed to ship and integrate seamlessly into existing quantum stacks. This focus on practicality ensures that researchers and industry partners can focus on advancing quantum applications rather than troubleshooting hardware. Additionally, Bifrost’s amplifiers are the only U.S.-made quantum-limited readout components, positioning the company as a key player in domestic quantum infrastructure.

"Unlocking quantum advantage will require bold engineering and new infrastructure built for scale."

— Dan Caruso, Managing Director of Caruso Ventures

Building a Quantum Ecosystem in Colorado

Headquartered at the Elevate Quantum campus in Arvada, Colorado, Bifrost is part of a burgeoning quantum technology hub. The company collaborates with industry leaders like Form Factor, Rigetti Computing, and Maybell Quantum Industries to tailor its amplifiers for commercial applications. This funding will enable Bifrost to expand its team, scale manufacturing, and deepen partnerships, further solidifying Colorado’s role as a national center for quantum innovation. Moreover, the Elevate Quantum campus fosters a collaborative environment where companies like Bifrost can drive advancements in quantum computing and microelectronics.

"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."

— Zachary Yerushalmi, CEO of Elevate Quantum

A Path to Quantum Advantage

By addressing one of the most persistent bottlenecks in quantum computing—reliable and scalable readout systems—Bifrost is paving the way for broader adoption of quantum technologies. The company’s focus on practical, high-performance solutions positions it to meet the needs of both researchers and commercial enterprises. As quantum computing moves from experimental labs to real-world applications, Bifrost’s quantum amplifiers will play a critical role in enabling this transition. With strong backing and a clear vision, Bifrost is poised to shape the future of U.S. quantum leadership.
