Bifrost Electronics

Bifrost Electronics is a Colorado-based quantum hardware startup founded in 2025, headquartered on the Elevate Quantum campus near Boulder. The company develops next-generation quantum readout and amplification hardware, creating a new class of traveling wave parametric amplifier (TWPA) that eliminates the need for Josephson Junctions. Their Heimdall TWPAs remain unaffected by magnetic fields over 2T, requiring no shielding and enabling dense packing in cryostats. CEO Zenith Tillemann-Dick notes that conventional quantum amplification devices are 'about the size of a cinder block' with 100,000 needed for utility-scale quantum computers—Bifrost built equivalent technology on a 10mm chip. In July 2025, the company raised $2.5M in seed funding led by Caruso Ventures with Harlow Capital. Bifrost collaborates with U.S. industry leaders including FormFactor, Rigetti Computing, and Maybell Quantum Industries to tailor systems for commercial deployments.
