GQCIRC (General/Go Quantum Circuit)

GQCIRC is a library for handling quantum circuits as Go data structures.

Features

• Handle Quantum Circuits in Go: Represent and manipulate quantum circuits programmatically using Go.
• Visualize Quantum Circuits: Draw and visualize quantum circuits.
• JSON Compatibility: Convert quantum circuit representations written in JSON into Go data structures.
  • We are planning to support other representation formats in the future.

Example

Here is an example of how to use GQCIRC to draw a quantum circuit from a JSON representation.

package main

import (
	"encoding/json"

	"github.com/massn/gqcirc"
)

var testQCJson = `
{
  "width": 4,
  "ops": [
    {
      "type": "gate",
      "target_qubit": 0,
      "name": "h"
    },
    {
      "type": "gate",
      "target_qubit": 1,
      "name": "x"
    },
    {
      "type": "gate",
      "target_qubit": 0,
      "name": "z"
    },
    {
      "type": "barrier"
    },
    {
      "type": "gate",
      "target_qubit": 1,
      "name": "h"
    },
    {
      "type": "gate",
      "control_qubits": [
        0
      ],
      "target_qubit": 1,
      "name": "cx"
    },
    {
      "type": "gate",
      "control_qubits": [
        1
      ],
      "target_qubit": 0,
      "name": "cx"
    },
    {
      "type": "gate",
      "control_qubits": [
        0,
        1
      ],
      "target_qubit": 2,
      "name": "cx"
    },
    {
      "type": "gate",
      "control_qubits": [
        0,
        2
      ],
      "target_qubit": 1,
      "name": "cx"
    },
    {
      "type": "measure",
      "target_qubit": 0
    },
    {
      "type": "measure",
      "target_qubit": 2
    }
  ]
}
`

func main() {
	var qc gqcirc.QC
	if err := json.Unmarshal([]byte(testQCJson), &qc); err != nil {
		panic(err)
	}
	conf := gqcirc.DefaultConfig
	conf.OutputSVGPath = "img/example2_out.svg"
	dConf := gqcirc.DefaultDiagramConfig
	dConf.Scale = 0.5
	gqcirc.Draw(&qc, &conf, &dConf)
}

This will generate an SVG image of the quantum circuit named example2_out.svg.
