GR¶

class GR(num_qubits, theta, phi)[ソース]¶

ベースクラス: qiskit.circuit.quantumcircuit.QuantumCircuit

Global R gate.

Circuit symbol:

     ┌──────────┐
q_0: ┤0         ├
     │          │
q_1: ┤1 GR(ϴ,φ) ├
     │          │
q_2: ┤2         ├
     └──────────┘

The global R gate is native to atomic systems (ion traps, cold neutrals). The global R can be applied to multiple qubits simultaneously.

In the one-qubit case, this is equivalent to an R(theta, phi) operation, and is thus reduced to the RGate. The global R gate is a direct sum of R operations on all individual qubits.

\[GR(\theta, \phi) = \exp(-i \sum_{i=1}^{n} (\cos(\phi)X_i + \sin(\phi)Y_i) \theta/2)\]

Create a new Global R (GR) gate.

パラメータ

num_qubits (int) – number of qubits.
theta (float) – rotation angle about axis determined by phi
phi (float) – angle of rotation axis in xy-plane

Attributes

ancillas¶

Returns a list of ancilla bits in the order that the registers were added.

戻り値の型: List[AncillaQubit]

calibrations¶

Return calibration dictionary.

The custom pulse definition of a given gate is of the form: {『gate_name』: {(qubits, params): schedule}}

戻り値の型: dict

clbits¶

Returns a list of classical bits in the order that the registers were added.

戻り値の型: List[Clbit]

data¶

Return the circuit data (instructions and context).

戻り値

a list-like object containing the tuples for the circuit’s data.

Each tuple is in the format (instruction, qargs, cargs), where instruction is an Instruction (or subclass) object, qargs is a list of Qubit objects, and cargs is a list of Clbit objects.

戻り値の型

QuantumCircuitData

extension_lib = 'include "qelib1.inc";'¶

global_phase¶

Return the global phase of the circuit in radians.

戻り値の型: Union[ParameterExpression, float]

header = 'OPENQASM 2.0;'¶

instances = 9¶

metadata¶

The user provided metadata associated with the circuit

The metadata for the circuit is a user provided dict of metadata for the circuit. It will not be used to influence the execution or operation of the circuit, but it is expected to be passed between all transforms of the circuit (ie transpilation) and that providers will associate any circuit metadata with the results it returns from execution of that circuit.

戻り値の型: dict

num_ancillas¶

Return the number of ancilla qubits.

戻り値の型: int

num_clbits¶

Return number of classical bits.

戻り値の型: int

num_parameters¶

Convenience function to get the number of parameter objects in the circuit.

戻り値の型: int

num_qubits¶

Return number of qubits.

戻り値の型: int

parameters¶

Convenience function to get the parameters defined in the parameter table.

戻り値の型: ParameterView

prefix = 'circuit'¶

qubits¶

Returns a list of quantum bits in the order that the registers were added.

戻り値の型: List[Qubit]
