How to prove that the distillable entanglement satisfies $E_D(|\psi_d\rangle\!\langle\psi_d|...
The distillable entanglement of this state is equal $\log d$ by definition. Thus, both $E_D(\lvert \psi_d\rangle\langle\psi_d\rvert)\ge \log d$ and $E_D(\lvert \psi_d\rangle\langle\psi_d\rvert)\le \lo …

What do entanglement cost and distillable entanglement have to do with measuring entanglement?
The entanglement entropy (what you call "von Neumann entropy") is a good measure for entanglement of pure states in the asymptotic setting, i.e. when one is dealing with many copies. However, it is n …

How can one impliment Bennett's partial measurement onto a binomial subspace for state disti...
Alice has to project onto the subspace with some number $n$ of $1$'s in their state $\lvert x_1,x_2,\dots,x_N\rangle$. This can be done by first running a circuit which adds the value of all $x_i$s an …
