Here, we present quantum software, BQ-Bank for option pricing, Value at Risk, portfolio optimization, and others. BQ-Bank can be run on a real quantum computer such as superconducting system or on an emulation system based on a classical computer with an interface. BQ-Bank, such as other quantum types of software, represents a new generation of the toolbox that likely brings disruptive innovations to the financial industry and banking market in the future. BQ-Bank also provides the classical Monte Carlo solution, so that users can compare their quantum results with classical ones directly. Our simulation results for a variety of examples show the superiority of quantum solutions.<\/jats:p>","DOI":"10.1155\/2023\/7810974","type":"journal-article","created":{"date-parts":[[2023,1,16]],"date-time":"2023-01-16T19:20:05Z","timestamp":1673896805000},"page":"1-10","source":"Crossref","is-referenced-by-count":4,"title":["BQ-Bank: A Quantum Software for Finance and Banking"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1177-0927","authenticated-orcid":true,"given":"Hang","family":"Li","sequence":"first","affiliation":[{"name":"Beijing Academy of Quantum Information Sciences, Beijing 100193, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tonghao","family":"Xing","sequence":"additional","affiliation":[{"name":"Beijing Academy of Quantum Information Sciences, Beijing 100193, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8312-1198","authenticated-orcid":true,"given":"Shijie","family":"Wei","sequence":"additional","affiliation":[{"name":"Beijing Academy of Quantum Information Sciences, Beijing 100193, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyuan","family":"Liu","sequence":"additional","affiliation":[{"name":"Beijing Academy of Quantum Information Sciences, Beijing 100193, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6720-2796","authenticated-orcid":true,"given":"Jiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing Academy of Quantum Information Sciences, Beijing 100193, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9023-1579","authenticated-orcid":true,"given":"Gui-Lu","family":"Long","sequence":"additional","affiliation":[{"name":"Beijing Academy of Quantum Information Sciences, Beijing 100193, China"},{"name":"State Key Laboratory of Low-Dimensional Quantum Physics and Department of Physics, Tsinghua University, Beijing 100084, China"},{"name":"Beijing National Research Center for Information Science and Technology and School of Information, Tsinghua University, Beijing 100084, China"},{"name":"Frontier Science Center for Quantum Information, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"5","key":"1","doi-asserted-by":"crossref","first-page":"563","DOI":"10.1007\/BF01011339","article-title":"The computer as a physical system: a microscopic quantum mechanical Hamiltonian model of computers as represented by turing machines","volume":"22","author":"B.
