Qx.Draw.SVG.Circuit (Qx - Quantum Computing Simulator v0.5.0)

View Source

SVG rendering of quantum circuit diagrams.

This module provides sophisticated SVG-based circuit visualization with:

  • Publication-quality IEEE-style gate notation
  • Support for all common quantum gates
  • Automatic gate layout with collision avoidance
  • Multi-qubit gates (CNOT, CZ, Toffoli)
  • Measurement operations with classical bit connections
  • Conditional gates (classical feedback)
  • Parametric gates with π-notation
  • Barrier markers for circuit organization

Circuit Diagram Features

  • Single-qubit gates: H, X, Y, Z, S, T, RX, RY, RZ, Phase
  • Multi-qubit gates: CNOT (CX), Controlled-Z (CZ), Toffoli (CCX)
  • Measurements: With visual connection to classical registers
  • Conditionals: Gates controlled by classical bit values
  • Barriers: Visual separators for circuit sections

Internal Module

This module is part of the Qx.Draw refactoring and should be accessed through the public Qx.Draw API rather than directly.

Summary

Functions

render(circuit, title \\ nil)

Renders a quantum circuit as an SVG diagram.

Functions

render(circuit, title \\ nil)

Renders a quantum circuit as an SVG diagram.

Parameters

  • circuit - Qx.QuantumCircuit struct to visualize
  • title - Optional circuit title (default: nil)

Returns

SVG string representing the complete circuit diagram.

Validation

Raises ArgumentError if:

  • Circuit exceeds 20 qubits
  • Invalid gate types are present
  • Qubit or classical bit indices are out of range

Examples

circuit = Qx.QuantumCircuit.new(2, 2)
|> Qx.Operations.h(0)
|> Qx.Operations.cx(0, 1)
