Qiskit [quiss-kit] is an open-source SDK for working with quantum computers
at the level of pulses, circuits, and application modules.
Qiskit Nature is one of Qiskit components. Qiskit Nature is an open-source
framework which supports solving quantum mechanical natural science problems
using quantum computing algorithms. This includes finding ground and excited
states of electronic and vibrational structure problems, measuring the dipole
moments of molecular systems, solving the Ising and Fermi-Hubbard models on
lattices, and much more.
The code comprises chemistry drivers, which when provided with a molecular
configuration will return one- and two-body integrals as well as other data that
is efficiently computed classically. This output data from a driver can then be
used as input in Qiskit Nature that contains logic which is able to translate
this into a form that is suitable for quantum algorithms.
For the solution of electronic structure problems, the problem Hamiltonian is
first expressed in the second quantization formalism, comprising fermionic
excitation and annihilation operators. These can then be mapped to the qubit
formalism using a variety of mappings such as Jordan-Wigner, Parity, and more,
in readiness for the quantum computation.
all: remove explicit versions in USES=python for "3.x+"
The logic in USES=python will automatically convert this to 3.8+ by
itself.
Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
