              Release Notes: This release now supports the density operator formalism. This approach allows it to study much larger quantum systems and mixed states where the exact quantum state is not known.

                Release Notes: The concept of quantum object code has been added. This allows you to trace the quantum operations that are executed. Possible applications of this interface are the analysis and optimization of quantum algorithms.

                  Release Notes: This release offers increased performance for many quantum gates, ports to GNU/Hurd and FreeBSD, and some minor additions like an unbounded Toffoli gate.

                    Release Notes: With this release, libquantum provides an interface for quantum error correction (QEC). An implementation of Grover's search algorithm is now included. Some additional functions for qubit manipulations have been added, e.g. a controlled phase kick.
