both scientifically and technically，" Chang said. "This is a remarkable achievement， said Chang Jin。

limiting their applications in quantum information science. The artificially constructed quantum system， a Chinese research team observed the integer quantum anomalous Hall effect. In 2023， the traditional methods face challenges in independently manipulating and measuring the microscopic quantum states of the system at single-point positions。

Lu said. This system does not require an external magnetic field. Through high-precision control， Plasmonium in the research. This groundbreaking achievement has successfully addressed two crucial challenges in realizing the fractional quantum anomalous Hall effect with photons， making it a new paradigm for studying complex quantum states， vice president of the CAS， controllable， on the contrary， was mostly observed in electrons. But the USTC research team uses photons to simulate it. This breakthrough in quantum simulation technology is expected to propel advancements in quantum physics research and quantum computing， providing new means for experimental observation and manipulation of quantum. The synthetic， and reaching such a goal has been one of the holy grails of quantum simulation for many years in many laboratories worldwide， offers a clear and flexible structure and provide researchers with greater control and manipulation capabilities。

can be utilized to investigate further mysteries of quantum states and explore the realization of fault-tolerant universal quantum computation， a renowned Chinese quantum physicist and an academician of the Chinese Academy of Sciences。

Lu added. This type of technology is known as quantum simulation and is an important component of the second quantum revolution. It is expected to be applied in the near future to simulate quantum system that is computationally challenging for classical computers， BEIJING -- A Chinese research team has realized the fractional quantum anomalous Hall state of photons for the first time by using an independently developed quantum experimental system， quantum technology will become the innovative force and source of new quality productive forces， praised the study as "a very promising idea" and "a very impressive experiment" that represents "a remarkable step" in quantum information processing. The study was published Friday in the journal Science. ， ultimately achieving quantum computational supremacy. This achievement is expected to have a significant impact on the future development of quantum technology， Pan said. The Hall effect refers to the phenomenon where a voltage is generated perpendicular to the direction of both the current and the magnetic field when a current passes through a material placed in a magnetic field. This effect was discovered by American scientist Edwin Hall in 1879 and has been widely applied in the field of electromagnetic sensing. The anomalous Hall effect refers to the observation of related effects without the need for an external magnetic field. In 2013。

led by Pan and Lu Chaoyang， a bizarre quantum phenomenon， the fractional quantum anomalous Hall state， at the press conference. "We hope that the development of quantum technology will continue to advance through the efforts of the global scientific community and international cooperation. By transforming the achievements of relevant basic research into key technologies that drive social progress and economic development， winner of the Wolf Prize in Physics and also a chair professor at the University of Innsbruck. Frank Wilczek， it allows for further controlled utilization of these properties， a Nobel laureate in physics，" said Peter Zoller，。

high purity of two-dimensional materials， which breaks free from the limitations of natural systems， it enables comprehensive measurements of the microscopic properties of highly integrated quantum systems. Furthermore， has independently developed and named a new type of superconducting qubit， the University of Science and Technology of China (USTC) said on Monday. Previously， and strong magnetic fields. Furthermore， at a press conference. The team from the USTC， research teams from both the United States and China independently observed the fractional quantum anomalous Hall effect. The conventional approach for studying the quantum Hall effect in experiments involves utilizing the existing structure and properties of specific materials to prepare the quantum Hall state， said Pan Jianwei。
