(Riverlane.News) Riverlane has reached a key stage in the commercial development of quantum computers with the successful trial of Deltaflow.OS, our high-performance, universal operating system.
In Deltaflow.OS, applications are implemented on quantum hardware through a carefully chosen interface, or “hardware abstraction layer”.
Since this approach enables rapid control of operations, Deltaflow.OS will improve the performance for near-term quantum computing applications by orders of magnitude compared to other interfaces, such as those used by IBM. For example, computational chemistry applications important in drug discovery or materials design, will run 30 times faster on near-term devices. When carrying out quantum error-correction, which is essential to build large and reliable quantum computers, the performance improvement due to Deltaflow.OS will be on the order of 1,000 fold. A standardised definition of this interface makes Deltaflow.OS portable to all four leading qubit technologies.
Dr Steve Brierley, CEO of Riverlane, said: “We have solved a really important problem in quantum computing: how hardware and software interact whilst teasing the highest possible performance out of a quantum computer. This finally shifts the complexity of designing quantum computer applications from hardware to software.”
Quantum computers currently producing calculations, such as those used by Google and IBM, run on bespoke operating systems invisible to external users. These are not portable to other hardware technologies or other labs. To external users, IBM offers an interface set at a very high level which leads to low-performance implementations.
“Quantum computing is currently where classical computing would be if it had to painstakingly produce an individual, tailored operating system for every existing conventional computer in the world. Not very far, in other words,” said Dr Brierley.
The trial demonstrated that Deltaflow.OS successfully completed a key technical task using the hardware abstraction layer– the ‘hello world’ requirement of quantum computing — known as a ‘Rabi oscillation’.
The task was carried out on a quantum computer at the University of Oxford in partnership with quantum hardware company Oxford Ionics, which operates with trapped-ion technology.
