GRY
class GRY(num_qubits, theta)
Bases: qiskit.circuit.library.generalized_gates.gr.GR
Global RY gate.
Circuit symbol:
┌──────────┐
q_0: ┤0 ├
│ │
q_1: ┤1 GRY(ϴ) ├
│ │
q_2: ┤2 ├
└──────────┘The global RY gate is native to atomic systems (ion traps, cold neutrals). The global RY can be applied to multiple qubits simultaneously.
In the one-qubit case, this is equivalent to an RY(theta) operation, and is thus reduced to the RYGate. The global RY gate is a direct sum of RY operations on all individual qubits.
Expanded Circuit:
Create a new Global RY (GRY) gate.
Parameters
- num_qubits (
int) – number of qubits. - theta (
float) – rotation angle about y-axis
Attributes
ancillas
Returns a list of ancilla bits in the order that the registers were added.
Return type
List[AncillaQubit]
calibrations
Return calibration dictionary.
The custom pulse definition of a given gate is of the form
{‘gate_name’: {(qubits, params): schedule}}
Return type
dict
clbits
Returns a list of classical bits in the order that the registers were added.
Return type
List[Clbit]
data
Return the circuit data (instructions and context).
Returns
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.
Return type
QuantumCircuitData
extension_lib
Default value: 'include "qelib1.inc";'
global_phase
Return the global phase of the circuit in radians.
Return type
Union[ParameterExpression, float]
header
Default value: 'OPENQASM 2.0;'
instances
Default value: 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.
Return type
dict
num_ancillas
Return the number of ancilla qubits.
Return type
int
num_clbits
Return number of classical bits.
Return type
int
num_parameters
Convenience function to get the number of parameter objects in the circuit.
