This document sets out a Hardware Abstraction Layer (HAL) for quantum computers (QHAL) based on four leading qubit technologies: superconducting qubits, trapped-ion qubits, photonic systems and silicon-based qubits. The aim is to define a multi-level HAL that makes software portable across platforms but not at the cost of performance. The HAL allows high-level quantum computer users, such as application developers, platform and system software engineers, cross-platform software architects, to abstract away the hardware implementation details while keeping the performance.
This specification must be considered a work in progress. The document is currently used to guide discovery, initiate discussion and enable future improvements. Even though all the parties involved are putting their best efforts on verifying the validity and correctness of what is stated, extensive reviews are still to be conducted. This disclaimer will be removed once the document reaches sufficient maturity.

The specification file gets updated every time a merge into the dev branch happens. Any PR that entails a change to the specification PDF document will not get built until merged into the dev branch, so during a PR any changes on the PDF that need to be inspected can be viewed as an artifact of this workflow. See specification for the latest version.
