SEEQC develops superconducting digital chips and hardware that control and read out qubits inside quantum computers. Rather than relying on room-temperature analog electronics and complex wiring, SEEQC places digital chips based on Single Flux Quantum logic directly inside cryogenic refrigerators near the qubits. This architecture generates high-precision control signals and reads qubit measurements with low latency and power consumption. SEEQC's product portfolio consists of digital qubit readout, digital flux and charge control blocks, and hybrid quantum-classical interfaces that link quantum processors to classical compute resources. In addition to chip design, SEEQC operates an in-house superconducting fabrication foundry in New York, which produces proprietary chips and provides commercial wafer fabrication services to outside customers. SEEQC sells primarily to quantum system developers and hardware integrators through staged co-development programs, engineering integration contracts, foundry services, and government development grants. SEEQC's long-term strategy is to transition from engineering services to supplying commercial hardware and software designed directly into scaling quantum computing systems across multiple qubit modalities.
