        # OpenQEMIST
        [![Build Status](https://travis-ci.com/1QB-Information-Technologies/openqemist.svg?token=zt4rNJ8MTUGcpVsToGyy&branch=master)](https://travis-ci.com/1QB-Information-Technologies/openqemist)
        
        Harnessing the combined power of emerging quantum computing technologies and
        state-of-the-art classical techniques, the Quantum-Enabled Molecular ab Initio
        Simulation Toolkit, or QEMIST, is 1QBit’s innovative solution to a fundamental
        and intractable problem in chemistry: ab initio simulation of molecules.
        
        QEMIST is designed to enable the accurate calculation of molecular properties by
        leveraging advanced problem decomposition (PD) techniques and quantum computing.
        The variety of PD techniques implemented in QEMIST enables massively parallel
        simulations by breaking down a computational chemistry task into smaller,
        independent subproblems. These subproblems can use a combination of interfaces
        to various classical and quantum solvers to achieve a higher level of accuracy
        for large-scale, practical molecular simulations.
        
        OpenQEMIST provides access to a portion of the functionalities of QEMIST as
        open source software under an Apache 2.0 license. For more information about the
        full functionality of QEMIST and to obtain additional information, please
        consult our main [product page](https://1qbit.com/qemist).
        
        ## Getting started
        
        To get started, install the package, then see the [Jupyter notebooks](https://github.com/1QB-Information-Technologies/openqemist/tree/master/examples)
        for example usage.
        
        To use the Rigetti integration, see the [instructions here](http://docs.rigetti.com/en/stable/start.html)
        to install and configure the QVM and Quilc compiler. Alternatively, use the
        provided docker-compose file to set up the environment.
        
        To use the Microsoft QDK integration follow the [instructions here](https://docs.microsoft.com/en-us/quantum/install-guide/?view=qsharp-preview)
        to install the required dependencies.
        
        ## Architechture of OpenQEMIST
        OpenQEMIST is organized into three layers: problem decomposition, electronic
        structure solvers, and hardware backends. The problem decomposition layer is
        responsible for splitting the input molecule into smaller subproblems and
        treating these using one particular eigenvalue solver (conceivably, fragments
        could be treated using multiple solvers), then processing these results into an
        overall output energy. Some electronic structure solvers use classical methods,
        while others use wrappers over quantum algorithms running on quantum computing
        emulators and simulators from quantum platform providers. The quantum solver
        backend layer implements a common interface over libraries, emulators, and
        simulators of quantum hardware.
        
        As OpenQEMIST includes only a portion of the functionalities incorporated in QEMIST, DMET
        is the only problem decomposition technique open sourced in our initial release.
        This release includes the Full CI and coupled-cluster with single and double
        excitations (CCSD) electronic structure solvers, as well as a quantum electronic
        structure solver based on the Variational Quantum Eigensolver (VQE) algorithm.
        
        On the hardware backend, this initial release is integrated with the Microsoft
        Quantum Development Kit for running the VQE algorithm.
