- Hello, is there an operational order between tensor and matrix multiplications?

Hello, I am calculating the krauss operators to find the new density matrix after the interaction between environment and the qubit.

My question is: Is there an operational order between matrix multiplication and tensor product? Because apparently author is first applying I on |0> and X on |0> and obtain

I|0> =|0>, and X|0>=|1>. instead of first calculating U.

Then instead of making the tensor product he is distributing <0| .

Can someone please explain me why that's the case?

On attachment you can find more detailed explanation.

Thanks in advance!
