0.14.2

Release created by workflow 25079027685.
GitHub commit 91ab3092e76dab8887d1fdf0c99a2478ca90581c

This release adds fixes for AWS Braket support.

Full Changelog: 0.14.0...2507902

0.14.0

This release comes with a range of exciting improvements.

• This release includes the first 0.1.0 version of CUDA-Q Realtime. CUDA-Q Realtime is built to support low-latency high-bandwidth data transfer between FPGAs and GPUs using NVQLink. CUDA-Q Realtime is installed separately via the C++ installer provided in the release assets. For more information about CUDA-Q Realtime, please see our docs.
• 0.14.0 adds support for Pre-Trajectory Sampling with Batch Execution (PTSBE). PTSBE can be used to capture millions of times more noisy shot data, which can then be used as training data in ML tasks such as AI decoders, or it can be deployed proportionally, capturing the exact statistics of the problem while still offering a considerable speedup. For more information, see our docs and applications.
• Starting with version 0.14.0, we now also distribute MacOS wheels on PyPI, and have made the C++ installer usable without root privileges.
• Additionally, we have completely overhauled the Python compiler. More details about the changes can be found in #3537 and #3693.

0.11.0

This release contains a range of ergonomic improvements and documentation updates. It adds support for initializing qubits to have a given state for quantum hardware backends and exposes a range of new configurations for different simulator backends. This release also addresses some performance issues with the initial introduction of a general operator framework in CUDA-Q. This required some breaking changes.

0.10.0

In this release we have added a range of tools for simulating noisy quantum systems. It includes support for trajectory based noise simulation for our GPU-accelerated statevector and tensor network simulators, and a new sampling option for better stim performance. We have also expanded the range of noise models, and added an apply_noise "gate". This release also adds the C++ support for the CUDA-Q dynamics backend (a master equation solver), as well as operator classes for fermionic, bosonic and custom operators. This release also includes support for submitting to Pasqal backends, and adds C++ support for QuEra. Check out our docs, including new tutorials and examples, for more information.

Note: Support for CUDA 11 will be removed in future releases. Please update to CUDA 12.

Full Changelog: 0.9.1...0.10.0
Release created by workflow 13913105388.

0.9.1

This release adds support for using Amazon Braket and Infeqtion's Superstaq as backends.
Starting with this release, all C++ quantum kernels will be processed by the nvq++ compiler regardless of whether they run on a simulator or on a quantum hardware backend. This change is largely non-breaking, but language constructs that are not officially supported within quantum kernels will now lead to a compilation error whereas previously they could be used when executing on a simulator only. The previous behavior can be forced by passing the --library-mode flag to the compiler. Please note that if you do so, however, the code will never be executable outside of a simulator and may not be supported even on simulators.

0.9.0

We are very excited to share a new toolset added for modeling and manipulating the dynamics of physical systems. The new API allows to define and execute a time evolution under arbitrary operators. For more information, we refer to our docs.
The 0.9.0 release furthermore includes a range of contribution to add new backends to CUDA-Q, including backends from Anyon Technologies, Ferimioniq, and QuEra Computing, as well as updates to existing backends from ORCA and OQC.
A more extensive list of the most important changes, as usual, is given below. We hope you enjoy the new features - also check out our new notebooks and examples to dive into CUDA-Q.
