Simulators

DDSIM offers different kinds of simulators to use. The following documentation gives an overview of the different simulator followed by brief demonstrations of the usage in Python and as standalone executable.

All simulators immediately, or with steps in between, inherit from the abstract Simulator class that provides basic functionality used by multiple actual simulators.

• Circuit Simulator
  • Simulating a simple circuit
  • Using Qiskit QuantumCircuit objects as input
  • Simulating a circuit with mid-circuit measurements
  • Usage as a Qiskit backend
  • Usage as standalone C++ executable
• Noise-aware Simulator
  • Usage in Python
  • Usage as Standalone Executable
• Simulation Path Framework
  • Simulating a simple circuit
  • Using CoTenGra to translate tensor network strategies
  • Configuration
• Hybrid Schrödinger-Feynman Simulator
• Unitary Simulator
  • Computing a simple unitary
  • Examples
    • Multiple qubits and qubit ordering
    • Multi-controlled quantum operations
    • Unitary of a complete circuit
    • Decision diagrams are not always compact
  • Usage as a Qiskit backend
  • Alternative construction sequence
