Web19 Apr 2024 · Here, we introduce and experimentally demonstrate a different protocol to measure the second-order Rényi entropy S (2), which is based on and extends the proposals in (20–23).Key strengths of the protocol are that it requires preparation of only a single copy of the quantum system at a time and can be implemented on any physical platform with … WebFor the entropy calculation, the system is divided into two parts A and B, where A (B) is the left (right) half of this eight-site system. The second Rényi entropy is defined as S (2) A = − log ...

This article explores a graph clustering method that is derived from an information theoretic method that clusters points in R n relying on Renyi entropy, which … Web24 Apr 2024 · Hi good question. Getting the von Neumann entropy of a mixed state \rho which is in the form of an MPO is not an easy task, and how best to do it is somewhat of an open research question. But obtaining the Renyi entropy, especially the second Renyi entropy S_2 is something straightforwardly computable with MPOs.. For others reading …
As α approaches zero, the Rényi entropy increasingly weighs all events with nonzero probability more equally, regardless of their probabilities. In the limit for α → 0, the Rényi entropy is just the logarithm of the size of the support of X. The limit for α → 1 is the Shannon entropy. As α approaches infinity, the Rényi … See more In information theory, the Rényi entropy is a quantity that generalizes various notions of entropy, including Hartley entropy, Shannon entropy, collision entropy, and min-entropy.
