New Quantum Intermediate Representation Alliance Serves as Common Interface for Quantum Computing Development

QIR Alliance is part of the Linux Foundation’s work on open standards

SAN FRANCISCO, November 30, 2021 – The Linux Foundation, the non-profit organization enabling mass innovation through open source, today announced the new QIR Alliance, a joint effort to establish intermediary representation with the aim of facilitating interoperability within the quantum ecosystem and providing a suitable representation for current and future heterogeneous quantum processors. The founding members are Honeywell, Microsoft, Oak Ridge National Laboratory, Quantum Circuits Inc. and Rigetti Computing.

QIR, or Quantum Intermediate Representation, is based on the popular open source LLVM compiler toolchain. QIR specifies a set of rules to represent quantum programs in the LLVM IR. Examples of QIR applications include using the standard LLVM infrastructure to write quantum optimizers that run on QIR and target it to specific hardware backends or link it to classic high-performance libraries for quantum simulation.

“We expect there will be exciting advances in how classical and quantum computations can interact at the hardware level. The QIR Alliance will provide a unique representation that can be used both for constrained capabilities today and for more powerful systems of the future, ”said Bettina Heim, senior director of software engineering at Microsoft. “This will allow the community to experiment and develop optimizations and code transformations that work in a variety of use cases. “

Quantum SDKs and development languages ​​are emerging and evolving at a rapid pace, along with new quantum processors with unique and distinct capabilities from each other. To ensure interoperability between new languages ​​and new hardware capabilities and reduce development efforts by all parties, it is imperative that the ecosystem develops and shares a forward-looking intermediate representation that works with current quantum hardware. and future.

“Quantum technology is still fairly nascent, but the promise is growing every day,” said Seth Newberry, general manager of standards at the Joint Development Foundation. “The QIR Alliance stands ready to enable the open and technical development necessary to deliver on these promises. We are very happy to provide a forum for this work.
