GR¶
- class GR(num_qubits, theta, phi)[소스]¶
기반 클래스:
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.

- 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.- 반환 형식
