Quantum adaptation of noisy channels
Original language description
Probabilistic quantum filtering is proposed to properly adapt sequential independent quantum channels in order to stop sudden death of entanglement. In the adaptation, the quantum filtering does not distill or purify more entanglement, it rather properlyprepares an entangled state to the subsequent quantum channel. In particular, the quantum adaptation probabilistically eliminates the sudden death of entanglement of a two-qubit entangled state with isotropic noise injected into separate amplitude damping channels. The result has an application in quantum key distribution through noisy channels.

Kvantová adaptace šumových kanálů
Czech description
V práci je navrhnut kvantový filtr umožňující adaptaci nezávislých kvantových kanálů za účelem zastavení náhlé ztráty kvantové provázanosti. Výsledek má aplikaci v kvantové kryptografii skrz šumové kanály.
