Front Cover of Advanced Quantum Technologies: Spatial Mode Correction of Single Photons Using Machine Learning

Researchers from 海角社区 have introduced a smart quantum technology for the spatial mode correction of single photons. In a paper featured on the cover of the March 2021 issue of , the authors exploit the self-learning and self-evolving features of artificial neural networks to correct the distorted spatial profile of single photons.

The authors, PhD candidate , postdoctoral researcher , graduate student , undergraduate student , and Assistant Professor of 海角社区鈥攖ogether with collaborators , , and of Tulane University and of Qingdao University of Science and Technology鈥攔eport on the potential of artificial intelligence to .

鈥淭he random phase distortion is one of the biggest challenges in using spatial modes of light in a wide variety of quantum technologies, such as quantum communication, quantum cryptography, and quantum sensing,鈥 said . 鈥淚n this paper, we use artificial neurons to correct distorted spatial modes of light at the single-photon level. Our method is remarkably effective and time-efficient compared to conventional techniques. This is an exciting development for the future of free-space quantum technologies.鈥

The newly developed technique boosts the channel capacity of optical communication protocols that rely on structured photons.

鈥淥ne important goal of the is to develop robust quantum technologies that work under realistic conditions,鈥 said 惭补驳补帽补鈥怢辞补颈锄补. 鈥淭his smart quantum technology demonstrates the possibility of encoding multiple bits of information in a single photon in realistic communication protocols affected by atmospheric turbulence. Our technique has enormous implications for optical communication and quantum cryptography. We are now exploring paths to implement our machine learning scheme in the (LONI) to make it smart, secure, and quantum.鈥 

The U.S. Army Research Office is supporting 惭补驳补帽补鈥怢辞补颈锄补鈥檚 research on a project titled 鈥淨uantum Sensing, Imaging, and Metrology using Multipartite Orbital Angular Momentum.鈥

鈥淲e are still in the fairly early stages of understanding the potential for machine learning techniques to play a role in quantum information science,鈥 said Dr. Sara Gamble, program manager at the Army Research Office, an element of DEVCOM ARL. 鈥淭he team鈥檚 result is an exciting step forward in developing this understanding, and it has the potential to ultimately enhance the Army鈥檚 sensing and communication capabilities on the battlefield.鈥

The Louisiana Quantum Initiative is a statewide endeavor to advance the research and technology of quantum systems in the context of the second quantum revolution and develop the strategy and technological infrastructure of quantum-driven networks and devices. The vast constellation of Louisiana scientists who are part of the initiative encompasses researchers from all over the state, from both public and private institutions. The initiative is an ecosystem of research that relies on emergent and dynamic associations and efforts among institutions as well as individual members.

The in the Department of Physics and Astronomy at 海角社区 investigates novel properties of light and their potential for developing quantum technologies. The team also conducts experimental research in the fields of quantum plasmonics, quantum imaging, quantum metrology, quantum simulation, quantum communication, and quantum cryptography.
