Company profile
SEEQC UK
London design and engineering operation of SEEQC Inc., developing superconducting single flux quantum digital chips used for control and readout of quantum processors. Chip fabrication takes place at the group's US facility.
Company overview
Developing chip-based quantum computing systems, SEEQC combines superconducting quantum circuits with classical Single Flux Quantum (SFQ) logic on a shared cryogenic platform. Its system-on-chip architecture places digital control electronics alongside qubits at the 20 mK temperature stage. The platform brings together quantum processing and classical functions including readout, control, error correction and data processing. SEEQC also operates a commercial multilayer superconducting chip foundry, with infrastructure for designing, testing and manufacturing quantum-ready superconductors. Founded in 2019 as a spin-out from Hypres, the company is based in Elmsford, New York, and reports facilities and teams in London and Naples. The supplied pages confirm a London presence but do not identify the specific design, fabrication or testing responsibilities of the UK team, or establish a separate UK headquarters or legal ownership structure.
