3.6.4. qupulse.pulses.interpolation

This module defines strategies for interpolation between points in a pulse table or similar.

Classes:

  • InterpolationStrategy: Interface for interpolation strategies.

  • LinearInterpolationStrategy: Interpolates linearly between two points.

  • HoldInterpolationStrategy: Interpolates by holding the first point’s value.

  • JumpInterpolationStrategy: Interpolates by holding the second point’s value.

class qupulse.pulses.interpolation.InterpolationStrategy[source]

Bases: object

Defines a strategy to interpolate values between two points.

abstract property expression

Returns a symbolic expression of the interpolation strategy using (v0,t0) and (v1, t1) to represent start and end point and t as free variable. Note that the expression is only valid for values of t between t0 and t1.

Return type

ExpressionScalar

abstract property integral

Returns the symbolic integral of this interpolation strategy using (v0,t0) and (v1,t1) to represent start and end point.

Return type

ExpressionScalar

class qupulse.pulses.interpolation.HoldInterpolationStrategy[source]

Bases: qupulse.pulses.interpolation.InterpolationStrategy

An InterpolationStrategy that interpolates by holding the value of the start point for the entire intermediate space.

property expression

Returns a symbolic expression of the interpolation strategy using (v0,t0) and (v1, t1) to represent start and end point and t as free variable. Note that the expression is only valid for values of t between t0 and t1.
