Quantum Entanglement of Discrete Systems

Define the coupled two-level systems:

singlet<- matrix(c(0, sqrt(0.7), sqrt(0.3), 0), byrow = TRUE, nrow = 2)

Schmidt Decompostions

Then run the Schmidt decompotions:

modes<- schmidt.decompose(singlet)

We can easily print the modes:

modes

And their corresponding entanglement entropy:

entanglement.entropy(modes)
