Qolab, a Santa Barbara hardware startup co founded by 2025 Nobel laureate John Martinis, will use the oversubscribed Series B to build superconducting quantum processors on standard silicon foundry lines rather than boutique cleanroom processes.
Qolab, the Santa Barbara quantum-computing hardware startup co-founded by 2025 Nobel laureate John Martinis, said it has closed an oversubscribed $54.2 million Series B led by the University of California's investment office.
The financing backs a specific scaling bet: that quantum processors will leave the bespoke laboratory and join the same semiconductor foundries that build classical chips. UC Investments, the University of California's Office of the Chief Investment Officer, anchored the round; existing backers Wisconsin Alumni Research Foundation (WARF), Octave Ventures, and Phoenix Venture Partners added follow-on capital, according to a write-up on Quantum Computing Report and Qolab's own release.
"Superconducting quantum processors" are chips that store information in the quantum states of superconducting electrical circuits operated near absolute zero. Qolab's stated thesis, per the company's release, is to design those chips around the constraints of standard silicon-foundry processes, a discipline the classical chip industry has spent decades refining and that most superconducting-quantum teams have historically bypassed in pursuit of record qubit counts. CEO Alan Ho framed the round, timed to the 75th Lindau Nobel Laureate Meeting, as fuel for an "industrialization" arc rather than a milestone chase, according to the announcement.
Inside the $54.2 million are about $12.6 million of convertible debt rolled into the round, plus a $10 million structured commitment for future convertible securities. That composition means the figure is not pure primary equity at the size of the reported headline; the cash-and-commitments component is smaller than the implied total.
The lead investor is unusual. UC Investments manages the University of California's long-term endowment and pension assets. Its placement at the front of the cap table, rather than as a limited partner in a venture fund, is a notable vote of confidence from a public-university investment office, and one that aligns with the company's institutional roots in the UC system.
The Nobel connection runs deeper than a founder credential. Martinis shared the 2025 Nobel Prize in Physics for work on macroscopic quantum tunneling and energy quantization, the physical phenomena Qolab's hardware depends on. Qolab separately announced a John Martinis Prize aimed at researchers working on scalable quantum hardware, a move that uses the CTO's name recognition to anchor the firm's narrative in scientific credibility rather than a single product cycle.
Nothing in the company's release claims working fault-tolerant quantum computers today, and no commercial quantum-advantage timeline is published. The test Qolab is setting for itself is engineering rather than physics: whether superconducting qubits can be fabricated at foundry-grade yield, with the coherence times (the window in which a quantum chip can reliably run calculations) that hold up as system sizes scale.
What to watch next: independent confirmation of the round through a regulatory filing or a UC Investments release; third-party benchmarking of yield and qubit metrics against the company's stated approach; and any move on manufacturing partnerships with silicon foundries. The capital is in. Whether the foundry can out-produce the cleanroom is the question the next few quarters of filings and benchmarks will answer.
