Linux Foundation announces Quantum Intermediate Representation Alliance (QIRA) to serve as common interface for quantum computing development

(HPCWire) he Linux Foundation has announced the new QIR Alliance, a joint effort to establish an intermediate representation with the goal to facilitate interoperability within the quantum ecosystem and provide a representation suitable for current and future heterogenous quantum processors. Founding members include 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 for representing quantum programs within the LLVM IR. Examples of QIR applications include using the standard LLVM infrastructure to write quantum optimizers that operate on QIR and target it to specific hardware backends or linking it with classical high performance libraries for quantum simulation.
Quantum development SDKs and languages appear and evolve at a fast pace, along with new quantum processors with unique and distinct capabilities from each other. To provide interoperability between new languages and new hardware capabilities and reduce development effort from all parties, it is imperative for the ecosystem to develop and share a forward-looking intermediate representation that works with present and future quantum hardware.
Founded in 2000, the Linux Foundation is supported by more than 1,000 members and is the world’s leading home for collaboration on open source software, open standards, open data, and open hardware. Linux Foundation’s projects are critical to the world’s infrastructure including Linux, Kubernetes, Node.js, and more. The Linux Foundation’s methodology focuses on leveraging best practices and addressing the needs of contributors, users and solution providers to create sustainable models for open collaboration
