- pygsti.report.reportableqty.minimum(qty1, qty2)
Returns a ReportableQty that is the minimum of qty1 and qty2.
Parameters
- qty1ReportableQty
First quantity.
- qty2ReportableQty
Second quantity.
Returns
ReportableQty
- pygsti.report.reportableqty.maximum(qty1, qty2)
Returns a ReportableQty that is the maximum of qty1 and qty2.
Parameters
- qty1ReportableQty
First quantity.
- qty2ReportableQty
Second quantity.
Returns
ReportableQty
- class pygsti.report.reportableqty.ReportableQty(value, errbar=None, non_markovian_ebs=False)
Bases:
objectA computed quantity and possibly its error bars, primarily for use in reports.
Parameters
- valueobject
The value, usually a float or numpy array.
- errbarobject, optional
The (symmetric) error bar on value. If value is an array, errbar has the same shape. None is used to signify “no error bars”.
- non_markovian_ebsbool, optional
Whether these error bars are “non-markovian”-type error bars (it can be useful to keep track of this for formatting).
Attributes
- sizeint
Returns the size of this ReportableQty’s value.
Initialize a new ReportableQty object, which is essentially a container for a value and error bars.
Parameters
- valueanything
The value to store
- errbaranything
The error bar(s) to store
- non_markovian_ebsbool
boolean indicating if non markovian error bars should be used
- property errorbar
Returns the quantity’s error bar(s)
Returns
- object
Usually a float or numpy array.
- property value_and_errorbar
Returns the quantity’s value and error bar(s)
Returns
- valueobject
This object’s value (usually a float or numpy array).
- error_barobject
This object’s value (usually a float or numpy array).
- nonMarkovianEBs
- absdiff(constant_value, separate_re_im=False)
Create a ReportableQty that is the difference between constant_value and this one.
The returned quantity’s value is given by (element-wise in the vector case):
abs(self - constant_value).
Parameters
- constant_valuefloat or numpy.ndarray
The constant value to use.
- separate_re_imbool, optional
When True, two separate real- and imaginary-part
ReportableQtyobjects are returned (applicable to complex-valued quantities).
Returns
- ReportableQty or tuple
The output ReportableQty`(s). If `separate_re_im=True then a 2-tuple of (real-part, imaginary-part) quantities is returned. Otherwise a single quantity is returned.
- infidelity_diff(constant_value)
Creates a ReportableQty that is the difference between constant_value and this one.
The returned quantity’s value is given by (element-wise in the vector case):
1.0 - Re(conjugate(constant_value) * self )
Parameters
- constant_valuefloat or numpy.ndarray
The constant value to use.
Returns
ReportableQty
- mod(x)
Creates a ReportableQty that holds this_qty mod x.
That is, the value and error bar (if present) are modulus-divided by x.
Parameters
- xint
Value to modulus-divide by.
Returns
ReportableQty
- hermitian_to_real()
Creates a ReportableQty that holds a real “version” of a Hermitian matrix.
Specifically, the returned quantity’s value is the real matrix whose upper/lower triangle contains the real/imaginary parts of the corresponding off-diagonal matrix elements of the Hermitian matrix stored in this ReportableQty.
This is used for display purposes. If this object doesn’t contain a Hermitian matrix, ValueError is raised.
Returns
ReportableQty
- reshape(*args)
Returns a ReportableQty whose underlying values are reshaped.
Returns
ReportableQty
- static from_val(value, non_markovian_ebs=False)
Convert Table values into ReportableQtys or leave them be if they are well-formed types.
Well-formed types include: * strings * figures *
ReportableQtyA tuple will be converted to a
ReportableQtyholding the first field as a value and second field as an error bar. Anything else will be converted to a ReportableQty with no error bars.Parameters
- valueobject
The value to convert.
- non_markovian_ebsbool, optional
Whether the error bars are of the “non-markovian”-type.
Returns
ReportableQty
- scale_inplace(factor)
Scale the value and error bar (if present) by factor.
Parameters
- factorfloat
The scaling factor.
Returns
None
- render_with(f, specs=None, ebstring='%s +/- %s', nmebstring=None)
Render this ReportableQty using the function f.
Parameters
- ffunction
The formatter function which separately converts the stored value and error bar (if present) to string quantities that are then formatted using ebstring, nmebstring or just “%s” (if there’s no error bar). This function must have the signature f(val, specs) where val is either the value or error bar and specs is a dictionary given by the next argument.
- specsdict, optional
Additional parameters to pass to the formatter function f.
- ebstringstr, optional
format string that describes how to display the value and error bar after they are rendered as string (ebstring should have two %s in it).
- nmebstringstr, optional
format string, similar to ebstring, for displaying non-Markovian error bars (if None then ebstring is used).
Returns
str
