However, there is a large gap between the generation rates achieved with existing physical sources and the high data rates of many computation and communication systems, which is a fundamental weakness in these systems. Here we show that good-quality random bit sequences can be generated at very fast bit rates using physical chaos in semiconductor lasers. Streams of bits which pass standard statistical tests for randomness have been generated at rates of up to 1.7 gigabit per second by sampling the fluctuating optical output of two chaotic lasers. This rate is an order of magnitude faster than that of previously reported devices for physical random bit generators with verified randomness.","subitem_description_type":"Other"}]},"item_120_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_120_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_120_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24561/00016480","subitem_identifier_reg_type":"JaLC"}]},"item_120_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_120_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学総合研究機構地域オープンイノベーションセンター"}]},"item_120_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18838278","subitem_source_identifier_type":"ISSN"}]},"item_120_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_120_text_3":{"attribute_name":"著者
