Difference Between SVD & Schmidt: Exploring |𝜓>AB

In summary, the main difference between SVD and Schmidt decomposition is the type of matrix they can be applied to. SVD is used for square matrices, while Schmidt decomposition is used for rectangular matrices. Both methods, however, help in exploring |𝜓>AB by breaking down the matrix into smaller, more manageable parts. SVD has advantages over Schmidt decomposition in its ability to handle rectangular matrices and its computational efficiency, but it cannot be used interchangeably as each method is specific to a certain matrix type. Schmidt decomposition also has limitations, such as its inability to handle square matrices and its computational expense for larger matrices. It is important to choose the appropriate method based on the matrix type in order to accurately analyze and explore |𝜓

What's the difference between Schmidt and Single valued decomposition?

https://www.physicsforums.com/showthread.php?t=323859

How could I find it for

[tex]

|\psi>_{AB} = const( |0>_A|0>_B+ |1>_A|1>_B) + const( |0>_A|1>_B+|1>_A|0>_B)

[/tex]

?

I haven't thought about how to do the Schmidt decomposition of that state vector, but you might find this thread more useful than the one you linked to.
 

What is the difference between SVD and Schmidt decomposition?

The main difference between SVD (Singular Value Decomposition) and Schmidt decomposition is the type of matrix they can be applied to. SVD is used for square matrices, while Schmidt decomposition is used for rectangular matrices.

How does SVD and Schmidt decomposition help in exploring |𝜓>AB?

SVD and Schmidt decomposition both help in exploring |𝜓>AB by breaking down the matrix into smaller, more manageable parts. This allows for a better understanding of the relationships and connections within the matrix, and can aid in simplifying calculations and solving problems.

What are the advantages of using SVD over Schmidt decomposition?

One of the main advantages of using SVD over Schmidt decomposition is its ability to handle rectangular matrices. SVD is also more computationally efficient and can be used for a wider range of applications, including image and signal processing.

What are the limitations of using Schmidt decomposition?

One limitation of Schmidt decomposition is that it can only be applied to rectangular matrices. Additionally, it can be more computationally expensive compared to SVD, especially for larger matrices.

Can SVD and Schmidt decomposition be used interchangeably?

No, SVD and Schmidt decomposition cannot be used interchangeably as they are used for different types of matrices. SVD is used for square matrices, while Schmidt decomposition is used for rectangular matrices. It is important to choose the appropriate method based on the matrix type to accurately analyze and explore |𝜓>AB.
