2、cience (QIS) is believed to have the potential to provide capabilities far beyond what is possible with the most advanced sciences available today. Quantum science, generally, is the study of the smallest particles of matter and energy; QIS builds on quantum science principles to obtain and process
3、information in ways that cannot be achieved through classical physics. QIS is based on the premise that information science depends on quantum effects in physics. Although much of the press coverage of QIS is on quantum computing, experts generally divide QIS into four categories: sensing and metrol
