Quantum Circuit Library

How to use this library

There are 7 library parts: 1q, 2q, 3q/3q+, 4q/4q+, 5q/51+, classical, useful, and construction-kit. The last part lets you construct your outlines of any circuit you wish.

Enabling mathematical typesetting | Zoom :-------------------------:|:-------------------------: To use latex notation in the circuits and overall diagram document, click in the menu bar on Extras -> Mathematical typesetting. | Use the zoom function by clicking on the magnifier under the menu bar. | |

Save to file | Load other libraries :-------------------------:|:-------------------------: Select File-> Export as and choose a format. You can also save only a selected part of your diagram. | When other forms are needed like dashed rectangles, load other libraries with + More Shapes option under the existing libraries. | |

Example

In this example, illustrated with short gifs, a three-qubit circuit diagram is put together, saved to the scratchpad, and loaded from it.

Prebuild 3 qubits initialization | By hand 3 qubits initialization :-------------------------:|:-------------------------: Drag and drop the wanted initialization gates, here it's three. | They could be assembled by the single qubit init gates when aligned properly. | |

Single qubit gate | Two qubit gate :-------------------------:|:-------------------------: Align the single qubit gate along with the init box, the alignment lines turn solid blue once the right position is met. | Now the two-qubit gate has to be aligned with the initialization and one qubit gate, again, the lines turn solid when it is aligned properly.| |

Toffoli Top | Toffoli Middle | Toffoli Bottom :-------------------------:|:-------------------------:|:-------------------------:| | | |

Measurement | Mathematical labeling :-------------------------:|:-------------------------: There are three different types of measurement boxes, here the one with no connector to the left is chosen to finish the diagram. | Labeling the diagram parts is possible even with latex notation, double click the box and put two doller signs $$ around the latex part.| |

Save to Scratchpad | Load from Scratchpad :-------------------------:|:-------------------------: Diagrams or parts of diagrams can be saved to the personal scratchpad. Select the parts and click the + sign next to the scratchpad to save it. | When clicking on the diagram in the scratchpad, the whole saved diagram appears again. | |
