<Function id="qiskit.circuit.random.random_circuit" isDedicatedPage={true} github="https://github.com/qiskit/qiskit/tree/stable/0.18/qiskit/circuit/random/utils.py" signature="random_circuit(num_qubits, depth, max_operands=3, measure=False, conditional=False, reset=False, seed=None)">
|
||
Generate random circuit of arbitrary size and form.
|
||
|
||
This function will generate a random circuit by randomly selecting gates from the set of standard gates in [`qiskit.extensions`](extensions#module-qiskit.extensions "qiskit.extensions"). For example:
|
||
|
||
```python
|
||
from qiskit.circuit.random import random_circuit
|
||
|
||
circ = random_circuit(2, 2, measure=True)
|
||
circ.draw(output='mpl')
|
||
```
|
||
|
||
|
||
|
||
**Parameters**
|
||
|
||
* **num\_qubits** (*int*) – number of quantum wires
|
||
* **depth** (*int*) – layers of operations (i.e. critical path length)
|
||
* **max\_operands** (*int*) – maximum operands of each gate (between 1 and 3)
|
||
* **measure** (*bool*) – if True, measure all qubits at the end
|
||
* **conditional** (*bool*) – if True, insert middle measurements and conditionals
|
||
* **reset** (*bool*) – if True, insert middle resets
|
||
* **seed** (*int*) – sets random seed (optional)
|
||
|
||
**Returns**
|
||
|
||
constructed circuit
|
||
|
||
**Return type**
|
||
|

|
||
|
||
**Raises**
|
||
|
||
**CircuitError** – when invalid options given
