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.
