Welcome to the Guha Lab
The Guha Group's research and educational interests lie in the engineering of materials, devices, and nanofabrication techniques for applications in future information processing systems. These include non-traditional systems such as those enabling quantum information processing, networked cyberphysical sensors and devices for distributed processing, and novel devices and materials for classical computing. Our interdisciplinary approach, augmented by our network of collaborators, facilitates the development of basic science concepts into engineering implementations.
Our team, led by Professor Supratik Guha, represents a mix of backgrounds and experience levels.
Our research spans a variety of areas, including novel nanofabrication techniques, quantum memory, and sensing networks.
Our group is always on the lookout for new researchers and project ideas, so feel free to get in touch if you're interested in joining.
News and announcements

November 2021: We are excited to announce that Emilio has received the 2021-2022 Quad Research Scholars award. Congratulations Emilio!

October 2021: Progress is ongoing in our current lab space in Searle Laboratory for constructing a new bonding chamber. The vacuum chamber will be used for studying atomic imprint crystallization and near-field depositions. Once installation is complete, this chamber will allow us to carry out experiments to create large area single crystals on amorphous substrates.

So far we've installed the horizontal and vertical sample manipulators, along with the gate valves, cryo pumps, and various viewports and other vacuum miscellany. Next to be installed are the turbopump and water cooling systems, and then the system is ready for use!

September 2021: Professor Guha has been featured in Protiviti's podcast "The Post-Quantum World" as a representative of Q-NEXT. You can listen to the episode here.

August 2021: Katie has been featured in an article posted with the Department of Energy and Argonne National Lab, discussing her ongoing research on quantum technologies. The article can be found here.

In other exciting news, Manish's paper on quantum repeaters is now available to read online. Check the Publications page to learn more.

July 2021: Manish, in collaboration with Prof. Liang Jiang, Prof. David Awschalom, and our own Prof. Supratik Guha, have been accepted for publication with IEEE Transactions on Quantum Engineering on a paper titled "Key device and materials specifications for a repeater enabled quantum internet". Congratulations Manish and team!

UChicago News on AIFARMS: The Guha Group joins the new Artificial Intelligence for Future Agricultural Resilience, Management, and Sustainability (AIFARMS) Institute, one of two national institutes funded by the NSF and USDA that will serve as a nexus for multidisciplinary research teams to advance foundational AI for addressing important challenges facing world agriculture. The AIFARMS institute is led by UIUC, with the University of Chicago, Michigan State, Tuskegee Institute and the Donald Danforth Plant Science Center as collaborating institutes, and Professor Guha as a co-PI of the project. The Guha Group contributes its experience in geospatial sensor networks for soil and water from the Thoreau project. More details on AIFARMS may be found here.

UChicago News on Q-NEXT: The Guha Group also joins the newly-announced Q-NEXT center hosted by Argonne National Laboratory, formed as part of the DOE's newly established Quantum Information Sciences Centers as part of the National Quantum Initiative. The Q-NEXT center will work to develop the science and technology required to control and distribute quantum information, with the Guha Group contributing its research into quantum memory and information processing.
