REUSE compliance of quantum-ket/ket

Unfortunately, gitlab.com/quantum-ket/ket is not REUSE compliant and does not fully adopt the recommendations to make software licensing easy for humans and machines alike. Have a look at our tutorial to learn about the three simple steps to become REUSE compliant.

Badge

To add the badge to your project's README.md file, use the following snippet:

[![REUSE status](https://api.reuse.software/badge/gitlab.com/quantum-ket/ket)](https://api.reuse.software/info/gitlab.com/quantum-ket/ket)

Machine-readable information

The API provides machine-readable artifacts for automatic analysis.

• All information about the latest compliance check can also be accessed via a machine-parsable JSON file.
• You can gather the automatically generated SPDX SBOM in Tag:Value format, based on the reuse spdx command.

# RECOMMENDATIONS

* Fix missing copyright/licensing information: For one or more files, the tool
  cannot find copyright and/or licensing information. You typically do this by
  adding 'SPDX-FileCopyrightText' and 'SPDX-License-Identifier' tags to each
  file. The tutorial explains additional ways to do this:
