Symplectic override on Ggate

[apchytr]

User description

Context: Ggate.symplectic should probably be returning the symplectic matrix it's defined with rather than recomputing.

Description of the Change: Overrride symplectic on Ggate to return the symplectic matrix stored in the param set.

Benefits: Avoid having to recompute the symplectic matrix

PR Type

enhancement, tests

Description

• Enhanced the Ggate class by overriding the symplectic property to return the symplectic matrix stored in the parameter set, avoiding recomputation.
• Updated the initialization method to use _add_parameter for adding the symplectic parameter.
• Added a test case to verify that the symplectic property returns the correct symplectic matrix.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Best practice	Add a tolerance parameter to the assertion for more robust testing Consider adding a tolerance parameter to the math.allclose() function call. This can help prevent potential issues with floating-point precision and make the test more robust. tests/test_lab_dev/test_transformations/test_ggate.py [33] -assert math.allclose(Eye.symplectic, math.eye(2)) +assert math.allclose(Eye.symplectic, math.eye(2), atol=1e-8) Apply this suggestion Suggestion importance[1-10]: 9 Why: Introducing a tolerance parameter to the 'math.allclose()' function call increases the robustness of the test by accounting for floating-point precision issues. This is an important enhancement for ensuring reliable test results.	9
	Add a docstring to the property for improved documentation Consider adding a docstring to the symplectic property to explain its purpose and return value. This will improve code documentation and make it easier for other developers to understand and use the property. mrmustard/lab_dev/transformations/ggate.py [66-68] @property def symplectic(self): + """ + Returns the symplectic matrix associated with this Ggate. + + Returns: + RealMatrix: The symplectic matrix. + """ return self.parameter_set.symplectic.value Apply this suggestion Suggestion importance[1-10]: 8 Why: Adding a docstring to the 'symplectic' property improves code documentation, making it easier for other developers to understand the purpose and return value of the property. This is a best practice that enhances code maintainability and usability.	8
Enhancement	Improve parameter naming for better code readability Consider using a more descriptive name for the parameter. Instead of s, use symplectic_matrix to improve code readability and make the purpose of the parameter clearer. mrmustard/lab_dev/transformations/ggate.py [61-64] self._representation = Bargmann.from_function( - fn=lambda s: Unitary.from_symplectic(modes, s).bargmann_triple(), + fn=lambda symplectic_matrix: Unitary.from_symplectic(modes, symplectic_matrix).bargmann_triple(), s=self.parameter_set.symplectic, ) Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion to rename the parameter from 's' to 'symplectic_matrix' enhances code readability and clarity, making the code easier to understand and maintain. This is a valuable improvement, although it does not affect the functionality.	7
