Bifrost Electronics, a Colorado-based quantum startup, has raised $2.5 million in seed funding. The round was led by Caruso Ventures, with participation from Harlow Capital and other investors. This funding is intended to accelerate the development of Bifrost’s quantum amplifiers, which are designed to address the readout bottleneck in quantum hardware.
Bifrost has developed a class of magnetically insensitive, scalable, electro-optic quantum amplifiers. The company’s approach involves applying materials science and precision engineering to its amplifier architecture, aiming to optimize systems for reliability and integration. Bifrost’s technology supports a range of qubit platforms, including superconducting qubits and spin qubits. The company states it is the only U.S. commercial producer of quantum-limited amplifiers and the sole producer of scalable, magnetically insensitive electro-optic amplifiers.
This funding round will support team expansion, scaled manufacturing, and continued partnerships with key ecosystem stakeholders. Bifrost is actively collaborating with U.S. industry entities such as Form Factor, Rigetti Computing, and Maybell Quantum Industries to tailor systems for commercial deployments. The company’s headquarters on the Elevate Quantum campus near Boulder, Colorado, positions it within a regional ecosystem focusing on quantum technology infrastructure.
