GR¶
- class GR(num_qubits, theta, phi)[ソース]¶
ベースクラス:
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.
\[GR(\theta, \phi) = \exp(-i \sum_{i=1}^{n} (\cos(\phi)X_i + \sin(\phi)Y_i) \theta/2)\]Expanded Circuit:
Create a new Global R (GR) gate.

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

- 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
