Version 3.5 - 8 March 2024

  • Replaced ["CHANGES"] by ["CHANGES.md"], as we now use Markdown format to keep track of changes in new releases
  • Removed pybind11 and GoogleTest dependencies; if not detected, they are installed automatically as build dependencies by CMake
  • Bumped GoogleTest version to HEAD latest, as recommended by Google
  • All header files are moved into ["include/staq"], so to include staq headers one now must #include "staq/<header>.hpp". This change was made for the sake of making the include statements look uniform in both non-installed (compiled without having staq installed) and installed (compiling with staq installed headers) modes.
  • Integrated the staq_ionq OpenQASM2 -> IonQ transpiler into pystaq

Version 3.4 - 1 December 2023

  • When configuring staq with cmake -B build -DINSTALL_SOURCES=ON, cmake --build build --target install now installs staq's source code in addition to the binaries
  • Renamed the ["examples"] directory to ["misc"]
  • Moved ["qpu_specs"] and ["scripts"] directories to ["misc"]
  • Added standalone source code example (requires staq's source installation) in the ["examples/standalone"] directory
  • Added staq_ionq OpenQASM2 -> IonQ transpiler

Version 3.3 - 6 October 2023

Version 3.2.3 - 14 August 2023

  • Minor bugfix in pystaq ["setup.py"] that prevented pip install from remote
  • Docker update, see the ["docker"] directory

Version 3.2.2 - 12 June 2023

  • This is a maintenance release
  • Compiling errors fixed on SunOS/OpenIndiana

Version 3.2.1

  • This is a maintenance release
  • CMake dependent flag name changes: USE_OPENQASM2_SPECS -> QASMTOOLS_QASM2_SPECS

Version 3.2 - 26 May 2023

  • This is a maintenance release
  • Migrated all continuous integration to GitHub actions
  • Minor updates in qasmtools

Version 3.1 - 13 May 2023

  • staq is now available on Homebrew (macOS/Linux), and can be installed with brew install staq
  • Migrated pystaq installation method to ["pyproject.toml"]
  • CMake minimum required version bumped to 3.15

Version 3.0.1 - 2 April 2023

  • This is a maintenance release with minor changes
  • Updated pybind11 to version 2.10.4

Version 3.0 - 20 March 2023

  • Complete Windows support for pystaq
  • Bumped GoogleTest version to 1.12.1
  • Implemented a lattice surgery compiler ["include/output/lattice_surgery.hpp"]

Version 2.1 - 17 January 2022

  • Added pystaq, a Python wrapper around staq. See this for more details.
  • Due to phase discrepancies, by default the parser now uses Qiskit definitions (which are also the usual ones used in QC textbooks). To switch to standard OpenQASM 2.0 gate definitions, configure the project with cmake -DUSE_OPENQASM2_SPECS=ON.
  • When building with CMake, the new STAQ_VERSION_NUM (numeric) and STAQ_VERSION_STR (string) preprocessor definitions are automatically injected in the code

Version 2.0 - 5 October 2021

  • Decoupled the OpenQASM parser from the main codebase. A hard copy of qasmtools is now common to both staq and Quantum++, and by default uses standard OpenQASM 2.0 gate definitions. To switch to Qiskit definitions (which are also the usual ones used in QC textbooks), configure the project with cmake -DUSE_QISKIT_SPECS=ON.
  • Added CMake installation support
  • Switched continuous integration from Travis CI to CircleCI
  • CMake minimum required version bumped to 3.12 for automatic unit tests detection by CMake
  • Unit testing is now a separate CMake target, one needs to explicitly type make unit_tests to build the unit testing suite
  • Simplified unit testing, now one can run tests with ctest or make test (after explicitly built with make unit_tests). Use GTEST_COLOR=1 ARGS="-V" make test or GTEST_COLOR=1 ctest -V for coloured verbose testing output.
  • QPU specifications (qubits, couplings, fidelities) are now stored in JSON files
  • Added a device generator to easily create these JSON files under ["tools/device_generator.cpp"].

Version 1.4 - 5 December 2020

  • Bugfixes
  • Renamed master branch to main

Version 1.3 - 11 June 2020
