Thomas A. Searles develops materials to bring quantum information science to life

Quantum information science and engineering stand to revolutionize our lives. Thomas A. Searles is working on the materials and tools required to bring applications of this technology to fruition.

Searles, an associate professor of electrical and computer engineering, works at the forefront of quantum information science, bridging the gap between physics and solid-state device and materials engineering. His research is in quantum information science and engineering, including light-matter interactions, quantum optics, terahertz spectroscopy, quantum materials, and metamaterials.

Quantum computing uses less energy and can process far more data much more quickly than traditional computing techniques—on order of a million times faster than what we use today. But there are daunting challenges to make quantum computing work on a commercial scale.

To approach those challenges, Searles holds that the full stack development of a quantum computer must involve electrical and computer engineers who are familiar not only with traditional methods of computing, but also with the different types of qubits, the basic units of quantum information.

Searles is working with several partners: the IBM-HBCU Quantum Center he built at Howard University; an ongoing NASA project with the Goddard Space Center, Tulane University, and Army Research Laboratory; and projects with students from Morehouse College and other Historically Black Colleges and Universities. He has received more than $12 million in research funding from the National Science Foundation, Air Force Office of Scientific Research, American Physical Society, Department of Defense, and others.

Searles sees Chicago as a hotbed for quantum information and forecasts exceptional opportunities for engineering physics in the next decade as a new quantum industry emerges here. He will offer a quantum photonics course in the near future.

Amit Trivedi making smart electronics smarter

Many people are interested in drones for aerial photography. Amit Trivedi is invested for other reasons.

Trivedi, an assistant professor of electrical and computer engineering, is developing millimeter-sized processors to fly insect-scale drones that will use machine learning to self-navigate. His work is supported by a National Science Foundation grant to produce robust and ultra-low-power spatial intelligence.

Trivedi’s tiny drones are designed for purposes far beyond photography: flying through debris to find survivors in a rescue operation or locating infected plants in an agricultural field to stem the spread of disease, for example. With only a few sensors, a tiny battery, and a lightweight camera, they will be able to operate by making decisions in real time, considering factors such as changes in lighting conditions or movements of people.

To achieve this kind of design, Trivedi plans to develop new hardware which uses computer vision to predict a drone’s future location, based on its past movement.

Trivedi’s goal is to expand the use of various sensing and control applications beyond their current uses, by demonstrating their compatibility with small, nimble autonomous devices.

The NICEST Lab Heading link

wireless communication devices

The NICEST Lab receives nearly $2 million in NSF funding to study, from both theoretical and practical perspectives, how to best communicate data over future wireless networks.

The lab’s faculty leaders, Natasha DevroyeHulya SeferogluBesma Smida, and Daniela Tuninetti, have been awarded three grants from the National Science Foundation towards this goal.

Devroye, Smida, and Tuninetti are co-principal investigators on the NSF funded project “CIF: Medium: Delay, reliability, rate tradeoffs in broadcast channels.” This four-year, $1.2 million grant will be used to determine the fundamental tradeoff between delay, transmission rate, and reliability for data transmission in wireless cellular networks. The grant has both an information theory and a communication theory component. How information is stored and transmitted across wireless networks, and how quickly the transmission of that information occurs, must be prioritized as different technologies come online in ever-increasing numbers.

Tuninetti received a three-year, $475,000 NSF grant to develop a framework for distributed computation, to enable faster information exchange for future data- and computation-intense applications. The grant, “CIF: Small: Fundamental Tradeoffs Between Communication Load and Storage Resources in Distributed systems,” covers two related problems: distributed cache-aided ‘Fog Radio Access Network’ architectures, which models a type of data network envisaged for 5G wireless systems, and peer-to-peer distributed data shuffling, which has applications in big data and machine learning.

Devroye and Wenjing Rao are co-PIs on an NSF grant of nearly $240,000 to develop a new framework for understanding, in a systematic, theoretically explained way, the fundamental limits and properties of Physically Unclonable Functions (PUFs). These computer hardware circuits, which are easily built into computer chips, are key to securing IoT devices but have been shown to be “machine learnable,” or capable of overhearing communicated data, and allowing an attacker to predict the behavior of the PUF, compromising security. The duo hopes to transform how PUFs are designed and used for authentication.

Distributed coded computations for Internet of Things

The Internet of Things (IoT) is emerging as a new Internet paradigm connecting an exponentially increasing number of smart IoT devices and sensors. IoT applications include smart cities, transportation systems, mobile healthcare and smart grid, to name a few. Unlocking the full power of IoT requires analyzing and processing this data through computationally intensive algorithms at unprecedented high rates, with stringent reliability, security, and latency constraints. In many scenarios, these algorithms cannot be run locally on the computationally limited IoT devices and are rather outsourced to the cloud. This leaves the IoT network, and the applications it is supporting, at the complete mercy of threats—for example, hackers, unfriendly nations, or natural disasters such as hurricanes or earthquakes—that can jeopardize the IoT or completely disconnect it from its “brain,” the cloud, with potentially catastrophic consequences. To mitigate the computational bottleneck in IoT, Dr. Seferoglu and her collaborators focus on the scenario that IoT devices help one another in their computations in a distributed fashion, with possible help from the cloud, if available. Their approach is based on the new theory of coded computations, which studies the design of erasure and error-correcting codes to improve the performance of distributed algorithms through “smart” data redundancy. Dr. Seferoglu and the team have developed distributed, adaptive, and secure coded computation algorithms for IoT devices, and they have deployed these algorithms on real IoT devices to demonstrate the efficiency of the approach.

Sudip K. Mazumder and power electronics

Sudip K. Mazumder receives grants for two projects, a high density onboard electric vehicle charger, and power and energy controls for surgical cutting tools.

Mazumder, a professor in the Electrical and Computer Engineering Department and the director of Laboratory for Energy and Switching-Electronic Systems (LESES), is the recipient of two grants funding this work: a Small Business Technology Transfer (STTR) Phase I grant from the NSF and a National Institute of Health grant with the University of Illinois at Urbana-Champaign.

The NSF grant has a very aggressive goal of developing a high-power gallium-nitride (GaN) transistor based onboard charger to be used on electric vehicles (EV). By eliminating the need for long charging times, an onboard charger could enable broader adoption of EVs. He is targeting a Level 2 EV charger specification for the onboard charger, but the technology can be scaled for higher power (and reduced charging time) by either having multiple charging modules working together, or using a three-phase input power.

The NIH grant is a project at the confluence of engineering and medicine, and Mazumder is the sole engineering expert from UIC on the project. Electrosurgery tools, which incorporate laser beams and harmonic/oscillating instruments, are typically operated at a fixed power level, sometimes damaging tissue and causing complications from excessive voltage. To mitigate these side effects, Mazumder is working on a distributed power electronics system that can precisely control the flow of energy during surgery. The power will vary based on the type of tissue, the thickness of the tissue, location, and tissue impedance.
