4. Problem 4 Consider the following set of operations applied to a bunch of pair of qubits shared by three different parties where the middle party plays the role of a repeater. ... ... Figure 2. A protocol to distribute entanglement 4-(a) What are the Quantum communication operations applied to get pictures from top to bot- tom? (Hint: Consider entanglement swapping, entanglement distillation, superdense cod- ing, teleportation, etc) 4-(b) What is the total number of classic bits transferred to get the bottom picture in the same figure? 4.
