SeeQC Inc

SEEQC Inc. is a quantum computing hardware company headquartered in Elmsford, New York, that develops a digital quantum computing platform based on superconducting chips. Its architecture places the core functions of a quantum computer — qubits together with classical control, readout and processing logic — on chips operating at millikelvin temperatures inside the cryostat, rather than relying on racks of room-temperature electronics connected by thousands of cables. The approach uses ultra-low-power Single Flux Quantum (SFQ) circuit technology and is described as qubit-agnostic, with potential applicability to superconducting, silicon spin and other qubit modalities. The company positions the design as a way to reduce input/output count, latency, heat load and overall full-stack complexity, which it frames as a prerequisite for large-scale quantum data centers.

Alongside its processor platform, SEEQC operates a 150mm multi-layer superconductive electronics chip fabrication facility in Elmsford valued at approximately $4 million, which has produced more than 5,000 distinct superconductive chip designs and supports design, simulation, layout, fabrication, cryogenic high-speed testing and packaging services. The foundry enables integration of application-specific superconducting hardware with qubit chips into 3D multi-chip systems. The company reports over 115 patents and maintains laboratories in multiple regions, including a facility in Naples, Italy. More recent work described in public reporting includes standardized quantum Process Design Kits integrated with the Cadence EDA ecosystem, a high-throughput cryogenic qubit evaluation platform for manufacturing feedback, and development of next-generation quantum computing systems-on-chip drawing on Taiwanese semiconductor manufacturing capabilities.

Founding story

SEEQC was formed as a spin-out from Hypres, a developer of superconducting electronics. Its founding group was led by John Levy and Oleg Mukhanov, both of whom previously worked at Hypres, together with Matthew Hutchings, who had participated in the Quantum Technology Enterprise Centre fellowship program at Bristol University. Mukhanov co-invented Rapid Single Flux Quantum (RSFQ) superconductor circuit technology during his PhD at Moscow State University in 1985 and led its development at Hypres. Levy, who serves as CEO, previously chaired Hypres and the distributed energy company BioLite and has a background in venture capital and private equity. Sources give the founding year variously as 2018 and 2019.

Business model

SEEQC combines development of its own digital quantum computing systems with chip foundry and fabrication services. Its Elmsford facility offers design, development, simulation, layout, fabrication, cryogenic high-speed testing and packaging of superconducting electronics for external parties, while the company also builds and deploys full-stack quantum systems accessible through a cloud portal. Public reporting additionally points to development of quantum Process Design Kits and licensing-adjacent positioning of its digital quantum control IP and system-level architecture in partnership with semiconductor manufacturers.

Revenue sources indicated by the sources include foundry and fabrication services (design, simulation, layout, fabrication, cryogenic testing and packaging of superconducting chips) and delivery of quantum computing systems and cloud-accessible platform access, alongside funded research collaborations. A third-party estimate places annual revenue between $1 million and $10 million as of July 2026.

Traction

SEEQC reports more than 115 patents, global laboratories and a foundry that has produced over 5,000 distinct superconductive chip designs. It demonstrated the SEEQC System Red full-stack quantum computer in Naples, described as Italy's first, and in March 2026 introduced a quantum processor operating at millikelvin temperatures with substantially reduced wiring. Third-party data places headcount at roughly 46 employees across North America and Europe as of July 2026, with estimated annual revenue in the $1M–$10M range. The January 2026 SPAC merger agreement valued the combined company at about $1 billion and included a $65 million PIPE.

Latest developments

In January 2026 SEEQC announced a definitive merger agreement with Allegro Merger Corp. at an approximately $1 billion valuation with a $65 million PIPE, expected to close in Q2 2026 pending regulatory and shareholder approvals, and reporting in June 2026 references a registration statement for a proposed initial public offering. Other 2026 developments include a millikelvin-temperature quantum processor with reduced wiring, standardized quantum Process Design Kits within the Cadence EDA ecosystem, a high-throughput cryogenic qubit evaluation platform, and work on next-generation quantum computing SoCs combining Taiwanese semiconductor manufacturing with SEEQC's digital quantum control IP.
