From improving methods for detecting diseases to facilitating more secure data transfer and enabling speedier computers, quantum materials hold a promise to transform daily life.

Quantum materials exhibit properties that can be understood using quantum mechanics, a branch of physics that helps explain the workings of the physical world at the fundamental level. 

However, quantum effects occur on subatomic scales and under very cold temperatures, appearing only for short periods, which makes studying them a challenge. 

Sanjay Behura, an assistant professor of physics at 色情视频鈥檚 College of Sciences is working with students to confront this challenge and help make quantum mainstream. 

鈥淨uantum is a growing industry, especially in San Diego and California more broadly,鈥� said Behura, who started at 色情视频 in Fall 2022 and is currently working under four federal research grants. 鈥淗ere at 色情视频, we are preparing students for the quantum workforce and hope to establish partnerships with local companies and government labs to provide further training opportunities.鈥�

Quantum science is the study of energy and matter at the fundamental level. Physicists have unlocked methods for integrating quantum science into a range of materials, giving them capabilities far beyond those of ordinary objects.

One type of quantum material is as thin as an atom and resides in only two dimensions, formed when a single two-dimensional layer is taken from a dry and granular bulk material. This process restricts the movement of electrons in the new material, which gives rise to quantum mechanical effects including enhanced electrical conductivity and transparency.

These electrical and optical properties have enabled revolutionary products like solar cells and mechanisms that power electronics. Think of your smartphone, for example. It conducts enough electricity to allow you to safely touch the screen and open Instagram but it is also transparent enough for you to observe what is happening behind it and catch up on all your friends have been up to.

New Applications

These unique properties give quantum 2D materials a myriad of important applications in areas including computing.

Quantum computers can run at incredibly high speeds because a qubit, or quantum bit, can access the digital information of 1s and 0s simultaneously instead of one at a time, as conventional computers do. As a result, in just a few hours, quantum computers can execute large, complex computational tasks that would take today鈥檚 computers thousands of years to complete.

Performing data analyses at these speeds can improve data encryption and help prevent adverse events like pandemics or market crashes.

鈥淏ecause quantum computers can process large amounts of data so much faster than classical computers, they could allow us to synthesize and model existing data in order to make predictions with more accuracy and efficiency,鈥� said Behura. 鈥淭his way, we can learn from the past to better prepare for the future.鈥�

Quantum materials can also be used in sensing technologies to enable better detection of diseases and more accurate and precise navigation systems like GPS. Additionally, they can allow for more secure communications by helping protect data transferred via phone calls, online banking or text messaging.

Behura鈥檚 teams of undergraduate, master鈥檚 and doctoral researchers are currently working on several projects that contribute to the expanding field of Quantum Information Science and Technology (QIST), including:

I-Corps: Developing a Face Mask Coated with Metal Oxide Nanostructures to Reduce the Spread of COVID and other Airborne Diseases

In this project, supported by a $50,000 grant from the National Science Foundation (NSF), researchers work to develop face masks coated in quantum materials to protect against airborne diseases. Because viruses spread via water droplets, the team seeks to take advantage of the fact that certain quantum materials are hydrophobic, meaning they repel water, by using them to create a coating along the inside of the 鈥渜uantum masks.鈥�

Two-dimensional Material Integrated Quantum Photonics Technologies

色情视频 recently joined Montana State University and University of Arkansas in this collaboration sponsored by MSU and NSF, which awarded a $350,000 grant. The goal of this project is to create quantum materials that can be grown at a large scale to enable quantum technologies.

Temperature-Dependent Topological Moir茅 Excitons in Twisted Transition Metal Dichalcogenides for Quantum Photonics

The objective of this project, sponsored by the Air Force Office of Scientific Research with a $200,000 grant and the University of Arkansas Pine Bluff, is to form 2D semiconductor heterostructures and study their optical properties. The insight gained from this project could contribute to quantum sensing applications. 

Direct Growth of hBN on SiN for Waveguide Coupled Quantum Light Emission

In this project, supported by a $200,000 grant from the Air Force Research Laboratory, researchers aim to grow 2D crystals and characterize their photonic properties. The team intends to apply this knowledge to create new quantum materials for technologies including sensing and computing.
