QuantumCircuit

Class describing basic circuit operations.

1. X-pauli gate.

   x(self, position: int) -> None:
       """
       X-pauli gate, also called not-gate, change |0> to |1> and |1> to |0>.
   
       :param position: index of qbit to be reverted
       :return: None
       """

2. Z-pauli gate.

   z(self, position: int) -> None:
       """
       Z-pauli gate, also called phase-flip-gate, leave |0> unchanged and replaces |1> with -|1>.
   
       :param position: index of qbit to be reverted
       :return: None
       """

3. H-pauli gate.

   h(self, position: int) -> None:
       """
       H-gate, called Hadamard gate, change status from |0> to (|0> + |1>)/sqrt(2) and |1> to (|0> - |1>)/sqrt(2).
   
       :param position: index of ubit to be reverted
       :return: None
       """

4. Show state of qubit.

   show_state(self) -> str:
       """
       Return current string representation of qbit.
   
       :return: string representation of qbit
       """

5. Measure qubit.

   measure(self) -> typing.Optional[str]:
       """
       Measure value of superpositioned qbit based on digital random module.
   
       :return: integer value 0 or 1 of measured qbits
       """

Drawing qubits

Set of functions for plotting quantum circuits.

1. Draw sample qubits on the plane.

   draw_qbit() -> None:
       """Draw sample qbits on the plane."""

2. Draw quantum state of qubit.

   draw_quantum_state(coords: typing.List[int], name: str, color: str = "blue") -> None:
       """
       Draw quantum state of qbit.
   
       :param coords: coordinates of quantum state on the plane.
       :param name: name of the quantum state to plot
       :param color: color of drawn arrow
       :return: None
       """
