View source on GitHub

Tools for converting Calibrations to NoiseProperties.

Given a Calibration "cal", a user can simulate noise approximating that calibration using the following pipeline:

<pre class="devsite-click-to-copy prettyprint lang-py">
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">cal = cirq_google.engine.load_median_device_calibration(&quot;rainbow&quot;)</code>
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">noise_props = cirq_google.engine.noise_properties_from_calibration(cal)</code>
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">noise_model = cirq_google.NoiseModelFromGoogleNoiseProperties(noise_props)</code>
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">simulator = cirq.Simulator(noise=noise_model)</code>
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">circuit = cirq.Circuit(cirq.X(cirq.GridQubit(5, 2)))</code>
<code class="devsite-terminal" data-terminal-prefix="&gt;&gt;&gt;">result = simulator.simulate(circuit)</code>
<code class="no-select nocode">    </code>
</pre>
