|
||
</Attribute>

|
||
</Attribute>
|
||
|
||
### clbits

||
|
||

|
||
</Attribute>
|
||
|
||
### data
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.data" />
|
||
|
||
### extension\_lib
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.extension_lib" attributeValue="'include "qelib1.inc";'" />
|
||
|
||
### global\_phase
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.global_phase">
|
||
Return the global phase of the current circuit scope in radians.
|
||
</Attribute>
|
||
|
||
### header
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.header" attributeValue="'OPENQASM 2.0;'" />
|
||
|
||
### instances
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.instances" attributeValue="177" />
|
||
|
||
### layout
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.layout">
|
||
Return any associated layout information about the circuit
|
||
|
||
This attribute contains an optional [`TranspileLayout`](qiskit.transpiler.TranspileLayout "qiskit.transpiler.TranspileLayout") object. This is typically set on the output from [`transpile()`](compiler#qiskit.compiler.transpile "qiskit.compiler.transpile") or [`PassManager.run()`](qiskit.transpiler.PassManager#run "qiskit.transpiler.PassManager.run") to retain information about the permutations caused on the input circuit by transpilation.
|
||
|
||
There are two types of permutations caused by the [`transpile()`](compiler#qiskit.compiler.transpile "qiskit.compiler.transpile") function, an initial layout which permutes the qubits based on the selected physical qubits on the [`Target`](qiskit.transpiler.Target "qiskit.transpiler.Target"), and a final layout which is an output permutation caused by [`SwapGate`](qiskit.circuit.library.SwapGate "qiskit.circuit.library.SwapGate")s inserted during routing.
|
||
</Attribute>
|
||
|
||
### metadata
|
||
|
||
<Attribute id="qiskit.circuit.library.FunctionalPauliRotations.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.
