- Acting with a superoperator to states in qutip
To do this in QuTiP, you have You can then act on this super ket with the super operator E|ρ E | ρ Note that for the equivalent operator U U acting on the state ρ ρ, Uρ U ρ is not necessarily equal to ρU ρ U So you have to keep tabs on whether the superoperator is left- or right-multiplied A nice explanation is given here In QuTiP, this is handled by calling spre(rho), spost(rho

- programming - Defining dimension of an operator in qutip - Quantum . . .
2 My main question: Can someone please explain to me how the list of array is used to define the dimension in qutip? Context: If I have my density operator A = Qobj(np arange(1,65) reshape(8,8)) of 3 qubits, how do I take the partial transpose such that I want to make bipartite entanglement between qubit 1 with qubit 2 and 3?

- Initialize circuit by density matrix (i. e. mixed state) by Cirq, Qiskit . . .
According to my investigation and experiments, we cannot initialize a circuit with mixed state density matrix trivially Finally, I used QuTip to perform the simulation and succeeded Please be critical of my following words, since it might be wrong If you use mixed state density matrix to initialize a circuit with Qiskit, it will check whether it is a pure state or mixed state and raised
