Quantum Program Drawing Tutorial

This document provides a guide on how to use the draw_qprog function to generate a graphical representation of a quantum program object (QProg).

Function Overview

The draw_qprog function generates a graphical representation of a given quantum program. It allows customization of the drawing format and options for detailed visualization.

Note

• expend_map: A map used to control drawing expansion options.Default: { {"all", 1} } (expands all subprograms). The key represents the name of the circuit to be unfolded,Values can be selected from 0, 1, 2. 0 represents not expanding, 1 represents expanding the current circuit without expanding its sub circuits, and 2 represents expanding all circuits.
• param_show: Indicates whether to show parameters in the drawing.Default: false.

Example Usage

Here’s a basic example of how to use the draw_qprog function:

Python

    from pyqpanda3.core import *
    prog = QProg()
    prog << H(1)<< H(0)
    circuit  = QCircuit()
    circuit << CNOT(1,2) << CNOT(2,3)
    prog << circuit
    print(draw_qprog(circuit))
    print(draw_qprog(prog)) # Expand all circuit
    print(draw_qprog(prog, expend_map={})) # Do not expand the circuit

The result output of the program is as follows:

q_1:  |0>────*── ────── 
          ┌──┴─┐        
q_2:  |0>─┤CNOT├ ───*── 
          └────┘ ┌──┴─┐ 
q_3:  |0>─────── ┤CNOT├ 
                 └────┘ 
 c :   / ═
 
 
 
 
          ┌─┐
q_0:  |0>─┤H├ ────── ────── 
          ├─┤
q_1:  |0>─┤H├ ───*── ────── 
          └─┘ ┌──┴─┐        
q_2:  |0>──── ┤CNOT├ ───*──
              └────┘ ┌──┴─┐
q_3:  |0>──── ────── ┤CNOT├
                     └────┘
 c :   / ═
 
 
 
 
          ┌─┐
q_0:  |0>─┤H├ ────────────────
          ├─┤ ┌──────────────┐
q_1:  |0>─┤H├ ┤0             ├
          └─┘ │              │
q_2:  |0>──── ┤1 QCircuit_0  ├
              │              │
q_3:  |0>──── ┤2             ├
              └──────────────┘
