Article on libquantum: Linux Magazin 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.
Thanks to the work of Florian Ragwitz, official Debian
packages of libquantum are now available in the unstable
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.
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.
Coreworld is an artificial life simulator using libquantum for
Release of libquantum 0.2.2: As the most important new
feature, the concept of quantum object code (quobcode) has been
added. This allows to trace the quantum operations that are
executed. Possible applications of this interface are the analysis
and optimization of quantum algorithms.
Mailing list available: libquantum-users is a
new mailing list where all topics and questions about libquantum can
be discussed and where new releases will be announced. Past messages
can be retrieved via the online archive.
Release of libquantum 0.2.1: The new release offers
increased performance for many quantum gates, ports to GNU/Hurd and
FreeBSD and some minor additions like an unbounded Toffoli
gate. Note that this release breaks backward compatibility, so your
programs will need recompilation. Take a look at the file
CHANGES for more.
Release of libquantum 0.2.0: 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. For all improvements and
bugfixes, see the file CHANGES.
Release of libquantum 0.1.1: This release fixes some
inconsistencies in the header files and a problem with the demo
