Pulser
==================================

**Pulser** is an open-source Python software package. It provides easy-to-use
libraries for designing and simulating pulse sequences that act on
programmable arrays of neutral atoms, a promising platform for quantum computation
and simulation.

Overview
---------------

Pulser is designed to let users create experiments that are tailored to a
specific device. In this way, you can have maximal flexibility and control over
the behaviour of relevant physical parameters, within the bounds set by the chosen device.

    Execution of a pulse sequence designed for a specific device.

Consequently, Pulser breaks free from the paradigm of digital quantum computing
and also allows the creation of **analog** quantum simulations, outside of the
scope of traditional quantum circuit approaches. Whatever the type of experiment
or paradigm, if it can be done on the device, it can be done with Pulser.

Additionally, Pulser features built-in tools for classical simulation to aid in
the development and testing of new pulse sequences.

To get started with Pulser, follow the instructions in :doc:`installation` and
check out the :doc:`programming` page to learn what mathematical objects you
are programming with Pulser and how to program them. Then, you can see examples
of quantum programs written with Pulser on :doc:`tutorials/creating`.
