Kraus decompostion of phase amplitude damping error is not appropriate

Yes, sure, you can transform this into each other but not for all parameter values (if $p_{amp} + p_{phase} > 1$ you will not find a solution for $t/T_1$ and...

Kraus decompostion of phase amplitude damping error is not appropriate

Yes, that's absolutely right and I'm already aware of the relations (see my [answer to a related question in Stackexchange](https://physics.stackexchange.com/questions/720139/what-is-the-connection-between-quantum-thermal-relaxation-and-phase-and-amplitud/722327#722327) 3 months ago). The only thing I want to say...

Samples of matrix product states should return probabilities

I don't think that's what I meant. Let's say we generated an MPS for 500 qubits. You can't store all probabilities here! You can only sample the MPS or measure...
