Bifrost Electronics appoints Doug Campbell as CEO ahead of quantum readout amplifier commercialization and market expansion.

Bifrost Electronics, a developer and manufacturer of advanced electronic hardware for quantum computers, announced that Doug Campbell has joined as Chief Executive Officer. Campbell brings over two decades of start-up leadership in commercial electronics, aerospace systems, and hardware manufacturing. He previously led Colorado-based battery technology company Solid Power from startup to IPO on the Nasdaq.

Bifrost is addressing readout-scaling problems for superconducting and spin-based quantum hardware with a new class of amplifiers that eliminates Josephson junctions. Traditional amplifiers relying on Josephson junctions require shielding, extra cryogenic lines, control electronics, and specialized manufacturing processes with nanometer tolerances. The Heimdall Amplifier is more robust, easier to scale, and requires less control hardware.

"The Bifrost team has built something the quantum industry genuinely needs, and I'm glad to be joining at this inflection point," Campbell said. "I've spent my career taking deep-tech start-ups out of university labs and into production at scale. The mission now is building the operational and commercial discipline to get the Heimdall Amplifier into customers' hands."

The Heimdall Amplifier provides qubit readout amplification without the operational fragility and magnetic sensitivity that have limited amplification deployment at scale. It is designed to run without shielding, pack densely inside a cryostat, and be produced with standard semiconductor manufacturing processes, enabling quantum hardware to scale from low-volume research systems to commercial production.

"Doug gives us the executive bandwidth to allow us to focus on what we do best—pushing the technology forward—while he builds the commercial engine around it," said Connor Denney, Bifrost co-founder and Head of Research and Development. "We're on track to complete rigorous testing over the coming months, and having a proven operator in place as we prepare for rollout gives the whole team confidence in the road ahead."

Bifrost is a spin-out from the Colorado School of Mines and has raised $5.5 million to date, led by Caruso Ventures with participation from Range Ventures. The company is headquartered on the Elevate Quantum campus in Arvada, Colorado.

Today, quantum-limited cryogenic amplifiers range from $25,000 to $45,000 each at research-grade volumes. The Heimdall Amplifier's CMOS-compatible fabrication pathway and architectural simplicity will lower that cost significantly and enable manufacturing at higher volumes.

"Doug's leadership role at Bifrost is another signal that quantum tech is moving into large-scale production," said Dan Caruso, Managing Director of Caruso Ventures and a member of Bifrost's board. "He is the right person to guide the company and map a successful path to commercialization with customers in the quantum sector as well as national labs and defense."

Campbell co-founded Solid Power in 2011 as a spin-out of the University of Colorado Boulder to commercialize all-solid-state battery technology. Under his leadership, Solid Power became the largest climate-tech venture from CU Boulder and one of nine companies with CU Boulder roots to reach unicorn status. He formed development partnerships with BMW, Ford, and SK On before taking the company public in 2021. Campbell also co-founded Roccor, a supplier of deployable structures for small satellites, which was acquired by Redwire Space in 2020.

"Colorado's quantum ecosystem is driving the entire industry forward and Bifrost Electronics is a vital part of that progress," said Jessi Olsen, CEO of Elevate Quantum. "Doug's leadership will be instrumental in bridging advanced materials and quantum capabilities to meet the rapidly growing demands of next-generation infrastructure."

Bifrost plans to roll out the Heimdall Amplifier later this year.
