Learn about Qiskit Aakash

Mar 26, 2021

Qiskit Aakash is a density matrix-based software simulator developed by the Indian Institute of Science (IISc), Bengaluru. The links provided on this page aim to explain how to use the new simulator (‘dm_simulator’) that has been added to existing Qiskit backends. Those links provide information only about the new backend. Tutorials related to other backends or Qiskit, in general, can be found here.

What is dm_simulator?

dm_simulator is a backend that can be called to execute circuits provided by the user. This backend uses density matrix formalism to calculate the subsequent changes in the qubit state as gates are applied. Density matrix formalism allows one to incorporate environmental noises in a convenient way. A few types of known noise models are implemented and can be invoked while calculating.

Learn more about the dm_simulator from the official GitHub page. The details about the implementation of the density matrix simulator have been explained in arxiv paper 1908.05154.
