Thank you Greg Bernhardt. It is ok for this. I will make other question.

Good day, May anyone help me to confirm the formula use for three tangle using concurrence. From my reading, three tangle, $$\tau=\tau_{A(BC)}-\tau_{AB}-\tau_{AC}$$ and it can be related to concurrence $$\tau=C^2_{A(BC)}-C^2_{AB}-C^2_{AC}$$ and I used formula for C is...

Thank you for respond it. It check it and yes,I made a mistake from multiply the matrix. Thank you all.

Thank you for respond. I want to make unitary transformation to the state B. When I run the coding, at certain time, the matrix become singular. How can I solve it hence it will give the result of the trace equal to 1

Thank you very much for helping me to solve my problem. Thank you again.thank you

Sorry for wrong matrix. It mean, I just do the tensor product?

From my reading, the X between SU(4)XSU(2) mean Cartesian product. But How the way to mutiply two matrix A in SU(4) and B in SU(2). Example the matrix A=\begin{pmatrix} a & b & c & d \\ e& f & g & h \\ i & j & k & l \\ m & n& o & p \end{pmatrix} and B=\begin{pmatrix} 1 &2 \\ 3 &4...

<< Mentor Note -- thread moved from Homework Help forums to General Math >>[/color] Good day, I run coding in Mathematica. But, I get singular matrix A at certain loop. In theory, how can I make matrix A become orthogonal A=\begin{pmatrix} 0& 0 & 0 & 0 & 0 & 0 & 0 & 0\\ 0& 0 & 0 & 0 & 0 &...

Thank you very much

Good day, I get confuse about the term used. Can anyone help me to explain: Tripartite system. Three qubit system. Tripartite entanglement. I really need help for me clarify these term. Thank you very much for helping me.

thank you so much .

Homework Statement Given a density matrix of three qubit pure state, how can I know after do some transformation, this state belong to what class?. Class I mean here, either separable state, biseparable, GHZ state or W state? I mean here what is the indicator to me classify it? It is the...

thank you. I understand about that but still don't get what happen if I only consider only certain parameter.It is will effect other or not?

Thank you so much for reply. From the parameter below SU(4), it has 15 parameter 1. 0 ≤ α1,α7,α11 ≤ π 2. 0 ≤ α3,α5,α9,α13 ≤ 2π 3. 0 ≤ α2,α4,α6,α8,α10,α12 ≤ π/2 4. 0 ≤ α14 ≤ √3 π 5. 0 ≤ α15 ≤ 2π √(2/3) and SU(2) 1. 0 ≤ β1,β3 ≤ π 2. 0 ≤β2≤ π/2 What I mean...

Homework Statement Good day, From my reading, SU(4) have 15 parameter and SU(2) has 3 parameter that range differently with certain parameter(rotation angle). And all the parameter is linearly independent to each other. My question are: 1. What the characteristic of each of the parameter? 2...
