public interface Gate
Interface representing a quantum gate.

A gate is a unitary operation that transforms quantum states. Every gate has a name and an arity (number of qubits it acts upon).

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    arity()
    Get the arity (number of qubits) this gate acts upon.
    String
    name()
    Get the name of this gate (e.g., "H", "X", "CNOT").

  • Method Details

    • name

      String name()
      Get the name of this gate (e.g., "H", "X", "CNOT").
      Returns:
      the gate name

    • arity

      int arity()
      Get the arity (number of qubits) this gate acts upon.
      Returns:
      1 for single-qubit gates, 2 for two-qubit gates, etc.
