A One-Shot Achievability Result for Quantum State Redistribution
Anurag Anshu, Rahul Jain, Naqueeb Ahmad Warsi · IEEE Transactions on Information Theory · 2017
We study the problem of entanglement-assisted quantum state redistribution in the one-shot setting and provide a new achievability result on the quantum communication required. Our bounds are in terms of the max-relative entropy and the hypothesis testing relative entropy. We use the techniques of convex split and position-based decoding to arrive at our result. We show that our result is upper bounded by the result obtained in Berta et al. (2016).
