Talk Title: Provenance Attestation: From Silicon Chips to Biological Cells and Beyond
Abstract: Complex processes, whether natural or artificial, often exhibit inherent variability and result in slightly different products even when identical steps, equipment, materials and conditions are employed. Such variability typically consists of a random component, which is attributed to the endogenous stochasticity of the process itself, and a systematic component, which is attributed to the exogenous aspects of the production. In this presentation, we will discuss how this variability can be harnessed for the purpose of attesting both the process and each copy of the product, thereby facilitating trust, traceability and intellectual property protection. First, in the context of semiconductor manufacturing, using production test measurements from integrated circuits fabricated in two different Texas Instruments 65nm facilities, we will demonstrate the use of contemporary statistical and machine learning-based methods for determining whether a chip was produced by a ratified foundry. Then, using both physical and electrical measurements (a.k.a., metrology and wafer acceptance tests, respectively) from wafers manufactured using multiple copies of a mask-set in a GlobalFoundries 12nm facility, we will demonstrate the use of similar methods for determining whether a wafer was produced by a trusted mask-set and we will discuss the design of custom sensors for obtaining the relevant information from each die on the wafer. Lastly, in the context of synthetic biology, using amplicon sequencing data from multiple cell lines (i.e., HEK293, HCT116 and HeLa), we will demonstrate that the stochasticity of the non-homologous end-joining (NHEJ) DNA repair process can be leveraged as a mechanism for introducing a unique identifier (i.e., a Genetic Physical Unclonable Function (PUF)) in every legitimately produced copy of a cell line. Akin to their counterparts in the semiconductor industry, Genetic PUFs can be used for attesting the provenance and protecting the intellectual property of valuable, genetically-engineered cell lines.

After spending a decade on the faculty of Yale University, he joined UT Dallas where he is now a Professor of Electrical and Computer Engineering, the Co-Founder and Site-PI of the NSF Industry University Cooperative Research Center on Hardware and Embedded System Security and Trust (NSF CHEST I/UCRC), as well as the Leader of the Safety, Security and Healthcare Thrust of the Texas Analog Center of Excellence (TxACE) and the Director of the Trusted and RELiable Architectures (TRELA) Research Laboratory. His research focuses on applications of machine learning and statistical analysis in the development of trusted and reliable integrated circuits and systems, with particular emphasis in the analog/RF domain. He has served as an Associate Editor of the IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, the IEEE Transactions on Information Forensics and Security and the IEEE Design & Test of Computers Periodical, and as a guest editor for the IEEE Transactions on Computers and the IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems. He also served as the 2016-2017 General Chair and the 2013-2014 Program Chair of the IEEE VLSI Test Symposium. He is a recipient of the 2006 Sheffield Distinguished Teaching Award, Best Paper Awards from the 2013 IEEE/ACM Design Automation and Test in Europe (DATE'13) conference and the 2015 IEEE VLSI Test Symposium (VTS'15), as well as Best Hardware Demonstration Awards from the 2016 and the 2018 IEEE Hardware-Oriented Security and Trust Symposia (HOST'16 and HOST'18) and a recipient of the 2020 Faculty Research Award from the Erik Jonsson School of Engineering and Computer Science at UT Dallas.

Talk Title: Scalable Manufacturing for Quantum Materials in Angstrom Precision
Series: Nano Science & Technology
Abstract: The figures of merit of quantum devices based on semiconductor and quantum materials are increasingly limited by imperfections introduced in nanofabrication. Further advances in capabilities demand both additive and subtractive manufacturing methods with vastly improved precision compared to that of typical approaches. In this talk, I will describe our development of additive manufacturing of bilayer graphene leveraging chemical vapor deposition and 'smart' processes. While the number of exciting quantum effects observed in bilayer graphene increases, a significant gap persists in transforming these discoveries into practical applications, owing to the small-scale samples obtained via top-down approaches. We realized a layer-by-layer (that is, Frank-van der Merwe) growth mode in large-scale bilayer graphene, with no island impurities, which is unprecedented in any van der Waals-stacked materials. Machine learning is adopted to assist spectroscopy, enabling the 'smart' characterization following the
chemical vapor deposition. After growth, a transfer is necessary to move bilayer graphene from the growth substrate to a destination substrate with a mandatory sacrificial support layer. This process induces residuals, wrinkles, and cracks, thus deteriorating 2D materials from their intrinsic properties. We utilized the Marangoni effect, also known as the 'tears of wine', to enable 'smart' transfer by building a surface tension gradient in transfer liquids. We demonstrate our autonomous Marangoni-flow transfer technique can transfer bilayer graphene without a support layer, resulting in residue-free bilayer graphene. In addition, I will discuss our recent progress in the subtractive manufacturing of semiconductors and quantum hardware in Angstrom precision using the atomic layer etching technique.
Biography: Dr. Haozhe Wang is currently KNI Prize Postdoctoral Fellow at the
California Institute of Technology (Caltech). He is working on atomic layer etching (ALE) technology for quantum materials to remedy surface imperfections in electronic and optical quantum devices. Before joining Caltech, he obtained his Ph.D. in Electrical Engineering from the Massachusetts Institute of Technology (MIT) in 2020, working on the scalable synthesis and application of quantum materials.

Talk Title: Building an Environmental Engineering Toolkit with Superconducting Circuits
Abstract: Many interesting systems, such as lasers and topological insulators, are dominated by both quantum effects and strong dissipation. Such systems can be characterized as sets of coherent quantum objects that interact with an uncontrolled quantum environment: an open quantum system. Such open quantum systems are a subject of intense theoretical research, but experimental tools have remained lacking. In this talk I cover some of my lab's work aimed at building experimental tools to customize quantum environments and so study open quantum systems effects. I will discuss how we can use noisy classical control, engineered quantum dissipation, and quantum weak measurement feedback in order to emulate desired environmental dynamics. I will also show how such techniques can be used in practical quantum computing and quantum simulation applications, suppressing errors and ensuring high-fidelity operation.
Biography: I received my bachelor's from Harvard in 2008 and then my PhD from UC Berkeley in 2013, where I worked in Irfan Siddiqi's Quantum Nanoelectronics Lab, conducting research on quasiparticles in superconducting circuits. I then worked as a postdoc at Stanford with Aharon Kapitulnik, researching unconventional superconductors and designing precision measurement experiments. In 2017 I began my appointment at USC in the Physics & Astronomy Department. I received Young Investigator awards from the AFOSR in 2018 and the ONR in 2021, and was named a Cottrell Scholar in 2021.
