quchip.analysis.vna¶

Continuous-wave scattering through declared Markovian ports.

Classes

`PortTone`(port, freq, amplitude, _index)	A fixed coherent input field entering through one declared port.
`VNA`(chip, *, input, outputs)	Sweep one input port and report complex output-field response.

class quchip.analysis.vna.PortTone(port, freq, amplitude, _index)[source]¶

Bases: object

A fixed coherent input field entering through one declared port.

Parameters:

port (str)
freq (Any)
amplitude (Any)
_index (int)

port: str¶

freq: Any¶

amplitude: Any¶

class quchip.analysis.vna.VNA(chip, *, input, outputs)[source]¶

Bases: object

Sweep one input port and report complex output-field response.

Parameters:

chip (Any)
input (Any)
outputs (list[Any] | tuple[Any, ...])

pump(port, *, freq, amplitude)[source]¶

Add a fixed background tone and return its variation handle.

Parameters:

port (Any)
freq (Any)
amplitude (Any)

Return type:

PortTone

vary(tone, parameter, values)[source]¶

Create a sweep axis for one fixed tone’s frequency or amplitude.

Parameters:

tone (PortTone)
parameter (str)
values (Any)

Return type:

Sweep

static zip(*variations)[source]¶

Pair tone variations element by element.

Parameters:: variations (Sweep)
Return type:: ZippedSweep

sweep(frequencies, *variations, amplitude=None, options=None, progress=False)[source]¶

Compute differential or finite-amplitude scattering response.

Parameters:

frequencies (Any)
variations (Sweep | ZippedSweep)
amplitude (Any | None)
options (dict | None)
progress (bool)

Return type:

SParameterResult

output_spectrum(output, *, frequencies, options=None)[source]¶

Return the normally ordered output fluctuation spectrum.

Frequencies are offsets in GHz from the stationary tone frame. The coherent carrier is reported separately because it is a delta peak, not a finite sampled spectral density.

Parameters:

output (Any)
frequencies (Any)
options (dict | None)

Return type:

OutputSpectrumResult

g1(output, delays, *, input=None, options=None)[source]¶

Return normalized first-order output coherence.

Parameters:

output (Any)
delays (Any)
input (Any | None)
options (dict | None)

Return type:

OutputCorrelationResult

g2(output, delays, *, input=None, options=None)[source]¶

Return normalized second-order output intensity correlation.

Parameters:

output (Any)
delays (Any)
input (Any | None)
options (dict | None)

Return type:

OutputCorrelationResult
