Recent Releases of qsim

qsim - qsim v0.22.0

This is a minor release that brings with it a number of updates:

  • Compatibility with NumPy 2
  • Compatibility with Cirq 1.5.0
  • Compatibility with Python 3.12–3.13
  • Compatibility with newer versions of CMake
  • Improvements and simplifications to the build and installation process. For example, the CMake configuration system will detect the availability of CUDA libraries automatically and build for the detected GPU hardware by default, even if environment variables like CUDAARCHS are not set.

Backward compatibility notes:

  • This release drops support for Python version lower than 3.10. This change is necessary to support NumPy versions 2.1 and higher.
  • The handling of Bazel configuration options has changed. qsim's behavior was previously inconsistent with the documentation about whether bazel build would use hardware vector optimization features by default. In this qsim release, support for those instruction set features is not compiled in by default; enabling them requires adding the appropriate Bazel config options. The options are documented in docs/bazel.md. (Note that this is specifically about Bazel and not the CMake configuration or the Makefiles.)

Apple Silicon note:

  • The ARM64/AArch64 architecture does not natively support the AVX or SSE instruction sets that qsim uses for vector optimizations. Consequently, on Apple Silicon, qsim will only build in the qsim_basic variant; i.e., without vector instructions. Being able to use those hardware features is a major element of qsim's performance advantages on other hardware, and its lack limits qsim's performance on Apple Silicon. Rewriting qsim to take advantage of ARM-specific SIMD features would require a substantial effort, and is not planned.

Finally, we thank Joseph Weston, the original owner of https://pypi.org/project/qsim, for letting us take over the qsim project name on PyPI and use it as an alias for qsimcirq going forward.
