  • 2013-01-29 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.
  • 2010-03-20 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.
  • 2008-09-09 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.
  • 2008-09-01 Bibliography: We have started a list of publications in which libquantum has been used. If you know other ones, please send us a mail.
  • 2008-04-27 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.
  • 2007-09-03 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.
  • 2005-11-21 Thanks to the work of Florian Ragwitz, official Debian packages of libquantum are now available in the unstable distribution.
  • 2005-01-11 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.
  • 2004-01-15 The Quantum Coreworld is an artificial life simulator using libquantum for quantum operations.
