<Function id="qiskit.ignis.verification.coherence_limit" isDedicatedPage={true} github="https://github.com/qiskit-community/qiskit-ignis/tree/stable/0.6/qiskit/ignis/verification/randomized_benchmarking/rb_utils.py" signature="coherence_limit(nQ=2, T1_list=None, T2_list=None, gatelen=0.1)">
|
||
The error per gate (1-average\_gate\_fidelity) given by the T1,T2 limit.
|
||
|
||
**Parameters**
|
||
|
||
* **nQ** (*int*) – number of qubits (1 and 2 supported).
|
||
* **T1\_list** (*list*) – list of T1’s (Q1,…,Qn).
|
||
* **T2\_list** (*list*) – list of T2’s (as measured, not Tphi). If not given assume T2=2\*T1 .
|
||
* **gatelen** (*float*) – length of the gate.
|
||
|
||
**Returns**
|
||
|
||
coherence limited error per gate.
|
||
|
||
**Return type**
|
||
|

float
|
||
|
||
**Raises**
|
||
|
