Abstract

Recently there have been much interests in quantum information science which makes the possible use of unique nature of quantum physics. In this field, entanglement, which is a quantum correlation between more than two quantum systems, plays an important role. Therefore entanglement distillation, which allows us to extract some higher entangled pairs from a larger number of less entangled pairs, is important in quantum information science and its realization is expected. Here we introduce entanglement distillation by our recent experimental demonstration as an example.
