SEEQC and IBM have announced a technical collaboration under DARPA’s Quantum Benchmarking Initiative (QBI) to investigate the integration of SEEQC’s Single Flux Quantum (SFQ) chip-based control technology with IBM’s quantum computing systems. The partnership aims to explore architectural solutions for consolidating classical control elements into cryogenic system-on-a-chip designs operating near quantum processors, enhancing energy efficiency and system compactness.
The collaboration will focus on addressing systems-level engineering challenges that are critical for scaling large fault-tolerant quantum computers. SEEQC’s SFQ-based digital control approach could potentially reduce the need for bulky room-temperature racks by relocating key control components inside dilution refrigerators, next to qubit chips. IBM, which continues to pursue its roadmap toward a fault-tolerant quantum computer by 2029, sees this effort as complementary to its broader goals.
Both companies are headquartered in New York and are active participants in the state’s growing quantum ecosystem. The collaboration underscores DARPA’s intent to drive performance metrics and benchmarking standards for useful, scalable quantum systems through public-private partnerships. It also highlights the role of regional clusters—such as New York’s NY QUANTUM Consortium—in facilitating progress across the full commercialization continuum.
