Release of libquantum 1.1.1: This new development version
features three different methods for the calculation of ground
states of arbitrary quantum systems. Further improvements include
better memory usage and increased performance, including support for
parallel computing.

A Rydberg quantum simulator: A new paper in Nature
Physics presents a proposal for creating a quantum simulator with
Rydberg atoms. Numerical results were obtained using libquantum, see
this blog post or the press release
for further details.

Release of libquantum 1.1.0 and 1.0.0: The 1.1.0
development version features a method for simulating the time
evolution of time-independent Hamiltonians based on exact
diagonalization. Additionally, using Runge-Kutta for time evolution
is now more flexible. Note that the 1.1.0 release is not backward
compatible to previous versions, see the file CHANGES for
further details. The 1.0.0 release is the first stable version of
libquantum, and contains fixes for bugs found in 0.9.1.

Article on libquantum: Linux-Magazin Online is currently running
a two-part series on libquantum (in German). The first
part gives a general introduction to quantum computing and
presents the main features of the library, the second
part illustrates the usage of libquantum in several examples.

Release of libquantum 0.9.1: This release adds an
interface for time-evolution of arbitrary Hamiltonians using a
fourth-order Runge-Kutta algorithm. The license has been changed to
GPLv3 and several bugs have been fixed. See the file CHANGES
for a complete list.

packages of libquantum are now available in the unstable
distribution.

Release of libquantum 0.2.4: This release fixes a bug in
the density operator formalism that caused a compiler error when
using certain gates.
2005-01-04
Release of libquantum 0.2.3: With this release libquantum
now supports the density operator formalism. This approach allows to
study much larger quantum systems and mixed states where the exact
quantum state is not known.
