Seeqc, the Digital Quantum Computing company, has achieved the first integration of all key functions towards an operating system on a chip. This breakthrough was achieved in partnership with Riverlane, UK developer of the first universal quantum operating system, Deltaflow.OS. This work was accomplished using the advanced commercial quantum measurement facilities QUES2T, operated by University College London.

“In its most simple terms, we have put something that once filled a room onto a chip the size of a coin, and it works,” said Dr. Matthew Hutchings, London-based chief product officer and co-founder of Seeqc.

Tight integration of Deltaflow.OS on Seeqc’s platform will enable Seeqc to maximise the low-latency performance available through its chip-scale technology. Low-latency performance is important for running quantum algorithms efficiently and achieving quantum advantage.

Dr. Hutchings said: “This is the first time we have built an integrated quantum computing chip based on our unique scalable architecture and run a programme on it. We achieved stability and full-stack control and, in so doing, also a remarkable moment for the evolution of quantum computing.”

“This is as significant for the future of quantum computers as the microchip itself was for commercialising traditional computers, allowing them to be produced cost-effectively and at scale,” Dr. Hutchings continued.

Dr. Steve Brierley, Founder and CEO of Riverlane said: “This successful demonstration of Deltaflow.OS onto Seeqc’s hardware is hugely encouraging. By combining quantum hardware and software expertise, we have solved a key challenge in quantum computing; ensuring portability and high performance across different qubit technologies.”

This important milestone was achieved by Seeqc’s UK team, which is focused on design and system integration. The work was supported by the NISQ.OS Innovate UK grant and achieved using the advanced commercial quantum measurement facilities at QUES2T, operated by University College London.

Prof. John Morton, Director of UCL's Quantum Science and Technology Institute (UCLQ) said: "This work by Seeqc and Riverlane highlights the key enabling role that the QUES2T millikelvin test facility is playing in supporting a wave of UK quantum computing start-ups to achieve their technical milestones." 

The QUES2T test facility based at UCL in central London is open to businesses and researchers looking to develop and test their quantum technologies. The facility has key infrastructure for the manufacture and testing of high-quality solid-state quantum devices including thin-film growth, advanced patterning, and low-temperature measurement test-beds.
