SEEC (pronounced "seek".[1]) is an American quantum computing company developing digital quantum computing systems based on superconducting integrated circuits[2]. The company specializes in combining quantum processors with cryogenic digital control electronics, an architecture intended to reduce latency, power consumption, and system complexity by placing control and readout functions inside cryogenic environments. Headquartered in Westchester New York[3], SEEQC has partnered with NVIDIA[4], IBM[5], Booz Allen Ventures[6], and the United Kingdom's National Quantum Computing Centre[7].
History
[edit]SEEQC was established in 2018 as a spinout from Hypres[8], a superconducting electronics company known for developing rapid single flux quantum (RSFQ) digital circuits and superconducting integrated circuit fabrication technologies.
SEEQC was founded by John Levy and Oleg Mukhanov to commercialize a new architecture integrating superconducting digital electronics directly with quantum processors. Unlike conventional quantum computing systems that rely heavily on room-temperature electronics connected through extensive cabling, SEEQC's approach moves portions of the control stack into cryogenic environments operating alongside quantum processors[9]
The company raised venture financing from investors including Merck's corporate venture arm, M Ventures[10], and other institutional investors.
Technology
[edit]A distinguishing feature of SEEQC's architecture involves using Single Flux Quantum (SFQ) digital logic that operates at cryogenic temperatures. These circuits generate digital control pulses and perform portions of the classical processing required to operate quantum processors, while consuming significantly less power than conventional semiconductor electronics.
In March 2026, Nature Electronics validated SEEQC's research by publishing a peer-reviewed demonstration of an integrated quantum processor unit combining superconducting qubits with Single Flux Quantum (SFQ) digital control electronics on the same millikelvin stage[11]. The study demonstrated single-qubit gate fidelities exceeding 99%, with results reaching 99.9%, while using digital multiplexing to reduce the number of control lines required as quantum systems scale[12].
"Imagine for a moment we were 10 years ago or 15 years ago with GPUs, and somebody simply asked the question, 'What’s the energy requirement going to be to run a scaled, GPU-based data center? What’s that going to look like, and is that an issue?'" SEEQC CEO John Levy told The Washington Post[13]. "That’s why SEECQ is scalable, energy-efficient quantum computing. Now we’re at a point where energy, for the first time, is gating computing power. And we’re seeing that play out dramatically. Look at all of the power infrastructure and the data center infrastructure that’s needed to make AI work right at scale and grow.[14]"
