        "description": "# StabGraph\n\nEvery stabilizer state can be transformed into a graph state by means of a local \nClifford unitary. stabgraph is contains the function `convert` that, given a \nstabilizer state, it finds such a graph state and the local Clifford unitary \nthat transforms the stabilizer state into the graph state. This function follows\nthe steps described in the article [1].\n\n[1] Manuscript under preparation. \n\n## Installation\n\nTo install using [pip](https://pip.pypa.io/en/stable/):\n\n```bash\npython -m pip install --upgrade pip\npython -m pip install stabgraph\n```\n\nReplace `python` with `python3` as appropriate.\n\n\n## Usage\n\n```python\nimport stabgraph\n\nG , c , t , z , R = stabgraph.convert(stabs,control=None,target=None,shuffle=False) \n```\n\nINPUT\n\n`stabs`     contains the N stabilizer operators defining a stabilizer state of N \n            qubits. It is a list of N strings 'PPPP...', one for each stabilizer \n            operator. Every string has N elements 'P' from the set 'I', 'X', 'Y', \n            'Z', that represents the set of Pauli matrices.\n\nOPTIONAL INPUTS\n\n`control`   is a list of control qubits. Gives the option to set some qubits as \n            control qubits. Qubits are labelled from 0 to N-1. It is an empy list by\n            default.\n\n`target`    is a list of target qubits. Gives the option to set some qubits as\n            target qubits. Qubits are labelled from 0 to N-1. It is an empty list by\n            default.\n\n`shuffle`   can be set to be True. For a given stabilizer state there are multiple \n            local Clifford equivalent graph states that can be obtained by this \n            program. If shuffle=True the output graph is one of these graphs chosen \n            randomly. shuffle=False by default.\n\nOUTPUTS\n\n`G`       adjacency matrix defining the underlying graph of the graph state. It is\n        a NxN numpy array composed by 0 and 1.\n\n`c`       list of control qubits labelled from 0 to N-1. The program completes the\n        list of control qubits given as an input.\n\n`t`       list of target qubits labelled from 0 to N-1. The program completes the\n        list of target qubits given as an input. A Hadamard gate is applied on\n        every target qubit.\n\n`z`       list of control qubits labelled from 0 to N-1 where a pi/2 z-rotation is\n        applied.\n\n`R`       invertible binary matrix representing the recombination of stabilizers\n        performed to obtain the stabilizers of the graph state. It is a NxN \n        numpy array composed of 0 and 1.\n\nEXAMPLES\n\nBell pair\n```\n>>> stabs = ['XX','ZZ']\n>>> G , c , t , z , R = stabgraph.convert(stabs)\n>>> G\nnp.array([[0,1],[1,0]])\n>>> c\n[0]\n>>> t\n[1]\n>>> z\n[]\n>>> R\nnp.array([[1,0],[0,1]])\n```\n\nGHZ state fixing 0 as a control qubit and 1 as a target qubit\n```\n>>> stabs = ['XXX','ZZI','IZZ']\n>>> G , c , t , z , R = stabgraph.convert(stabs,[0],[1])\n>>> c\n[0]\n>>> t\n[1,2]\n```\n\nSteane code in the |0> logical state. \nMultiple graphs can be obtained, so put `shuffle=True` to obtain one of them randomly chosen.\nThe result respects the selection of control and target qubits\n```\n>>> stabs = ['XXXXIII','IXXIXXI','IIXXIXX','ZZZZIII','IZZIZZI','IIZZIZZ','ZZZZZZZ']\n>>> G , c , t , z , R = stabgraph.convert(stabs, control = [0], shuffle=True)\n>>> c\n[0,1,2]\n>>> G , c , t , z , R = stabgraph.convert(stabs, control = [2, 5], shuffle=True)\n>>> c\n[2,5,6]\n\n```\n\n## Citation\n```\n@misc{amaro2019,\n  author = \t\"David Amaro\",\n  title = \t\"StabGraph\",\n  year = \t\"2019\",\n  month =   \"July\",\n  publisher = {GitHub},\n  journal = {GitHub repository},\n  howpublished = {\\url{https://github.com/davamaro/stabgraph}}\n}\n```\n\n\n",
