Limitations of local update recovery in stabilizer-GKP codes: a quantum optimal transport approach
Robert König, Cambyse Rouzé
Local update recovery seeks to maintain quantum information by applying local correction maps alternating with and compensating for the action of noise. Motivated by recent constru…
The entropy power inequality for quantum systems
Robert Koenig, Graeme Smith
When two independent analog signals, X and Y are added together giving Z=X+Y, the entropy of Z, H(Z), is not a simple function of the entropies H(X) and H(Y), but rather depends on…
Unconditional security from noisy quantum storage
Robert Koenig, Stephanie Wehner, Juerg Wullschleger
We consider the implementation of two-party cryptographic primitives based on the sole assumption that no large-scale reliable quantum storage is available to the cheating party. W…
The operational meaning of min- and max-entropy
Robert Koenig, Renato Renner, Christian Schaffner
We show that the conditional min-entropy Hmin(A|B) of a bipartite state rho_AB is directly related to the maximum achievable overlap with a maximally entangled state if only local…
Sampling of min-entropy relative to quantum knowledge
Robert Koenig, Renato Renner
Let X_1, ..., X_n be a sequence of n classical random variables and consider a sample of r positions selected at random. Then, except with (exponentially in r) small probability, t…
