![]() Furthermore, we apply the proposed codes in so-called one-way communication schemes to demonstrate their practical relevance. For both classes of codes, we investigate suitable performance measures and show how to generalize them from logical qubits to general logical qudits. of quantum information quantumstate channel errors w w erroneousstate Errors are induced by, e.g., interaction with an environment, coupling to a bath, or also by imperfect operations. We present exact quantum error correcting codes based on NOON states and linear optics as well as approximate codes based on coherent state superpositions. This talk is about quantum error correcting codes against photon loss as occurring in optical fibers. To achieve this, quantum repeaters exploiting quantum error detection and correction of photon losses have been proposed.

To make specific tasks like quantum teleportation or quantum key distribution over large distances possible, the exponential decay of photonic quantum information has to be compensated. Aalto Quantum Physics Seminar (Nanotalo). The realization of optical quantum communication protocols is still one of the most challenging tasks in quantum information. Optical quantum error correction against photon loss for qubits and beyond Seminar Speaker: Quantum systems can interact with one another and with their surroundings in ways that are fundamentally different from those of their classical counterparts.
