My current research focuses on engineering spin systems in diamond, silicon carbide, and other wide bandgap semiconductors for quantum information, nanoscale sensing, and quantum communication applications. These spin systems, such as the nitrogen vacancy (NV) center in diamond and the divacancy complexes (VV) in silicon carbide (SiC), offer a wide variation of control techniques as well as sensitivity to local magnetic and electric fields and temperature.

Ivar Martin is a condensed matter theorist in the Material Science Division.

His interests include equilibrium properties of materials, including superconductivity and magnetism, as well as nonequilibrium. Recently he has been particularly interested in the ways to create new quantum states by means of strong periodic and quasiperiodic driving.

His other interests include microscopic theory of quantum decoherence and quantum measurement, ways to implement unusual correlated states in quantum hardware, and classical nonlinear phenomena of phase and mode locking. 

Martin got his undergraduate degree from the Moscow State University, and PhD from the University of Illinois at Urbana-Champaign. In 1999 he went to Los Alamos National Lab, first as a postdoc and then as a staff member. He came to Argonne in 2013.

Dr. Iadecolais a theoretical physicist using diverse analytical and numerical tools to study a variety of topics in quantum condensed matter. A graduate of Brown University (Sc.B., 2012), he received his Ph.D. in Physics from Boston University in 2017. He then became a JQI Theoretical Postdoctoral Fellow at the NIST-University of Maryland Joint Quantum Institute until 2019, when he joined Iowa State University as an Assistant Professor. Research in his group focuses on out-of-equilibrium quantum systems and topological phases with a view towards emerging quantum technologies. On the nonequilibrium side, he studies properties of highly-excited many-body states and the surprising phenomena they harbor that challenge deeply ingrained intuition based on quantum statistical mechanics. On the topological side, he focuses on states of matter whose properties cannot be understood within the traditional paradigm of spontaneous symmetry breaking, and which could enable the robust storage and manipulation of quantum information. In addition to thinking about new phenomena, he grapples with ways to realize them in electronic and photonic systems, or using near-term quantum platforms.

Irfan Siddiqi received his AB (1997) in chemistry & physics from Harvard University. He then went on to receive a PhD (2002) in applied physics from Yale University, where he stayed as a postdoctoral researcher until 2005. Irfan joined the physics department at the University of California, Berkeley in the summer of 2006. In 2006, Irfan was awarded the George E. Valley, Jr. prize by the American Physical Society for the development of the Josephson bifurcation amplifier. In 2007, he was awarded the Office of Naval Research Young Investigator Award, the Hellman Family Faculty Fund, and the UC Berkeley Chancellor’s Partnership Faculty Fund.

His group, the Quantum Nanoelectronics Laboratory, investigates the quantum coherence of various condensed matter systems ranging from microscopic nanomagnets such as single molecule magnets to complex macroscopic electrical circuits. To measure the electric and magnetic properties of these quantum systems, they are developing novel microwave frequency quantum-noise-limited amplifiers based on superconducting Josephson junctions formed by both oxide tunnel barriers and carbon nanotube weak links. Current topics of research include the dependence of quantum coherence on system complexity, the non-equilibrium quantum statistical mechanics of non-linear oscillators, the quantum coherence of single molecules, and topological architectures for maximum coherence in superconducting circuits.

Thomas Schenkel is a physicist and senior scientist at Lawrence Berkeley National Laboratory, where he is the interim Director of the Accelerator Technology and Applied Physics Division (http://atap.lbl.gov/). Thomas received his Ph.D. in physics from the Goethe University in Frankfurt. Following time as a postdoc at Lawrence Livermore National Laboratory, he joined Berkeley Lab. His research interests include novel accelerator concepts, materials far from equilibrium, exploration of fusion processes, and spin qubit architectures. Thomas also teaches a graduate course on particle accelerators at UC Berkeley.

Thomas worked on variations of time-of-flight mass spectrometry to characterize the environment of bio-molecules as a postdoc. This theme has now come up in the current Covid-19 crisis with new ideas for mass spectrometry and imaging of viruses in droplets.

Susan Clark has been a scientist at Sandia National Laboratories since 2013 where she has worked on a variety of quantum information-related projects on different platforms, including trapped ions and gate-defined quantum dots in silicon. She is currently the PI of the DOE-funded Quantum Scientific Computing Open User Testbed (QSCOUT) at Sandia, a project which aims to build, maintain, and provide access to quantum hardware based on trapped ions to scientists around the world. Prior to joining Sandia, she did her postdoctoral work at the Joint Quantum Institute at University of Maryland with Chris Monroe. There, she researched quantum networking with trapped ions via photons and robust two-qubit gates via phonons. Prior to her postdoctoral work, she graduated with a PhD and Masters in Applied Physics from Stanford University in 2010. At Stanford, under the direction of Professor Yoshi Yamamoto, she studied and characterized a variety of optical solid-state qubits including electron spins of silicon donors in bulk GaAs and single fluorine donors in ZnSe.

My research focus is on point-defects (vacancies and dopants) in various semiconductors (Si, SiC, Y2O3, etc.) for material science and quantum information processing. I am interested in searching for the optimal defects and substrates depending on their applications, expanding on state-of-the-art understanding of charge, optical and spin properties. Applications include hybrid spin-mechanical quantum systems, decoherence mitigation, quantum communication and quantum and classical sensing. 

In 2008, I received my bachelor’s degree in applied physics from ENS Cachan and Université Paris 11, Orsay. I went on to receive my master’s in nanophysics in 2011 from the Saclay Campus near Paris and my Ph.D. in quantum physics in 2015 from the University of Oxford. From 2015 to 2019, I performed research as a postdoctoral fellow in the Awschalom group at the Institute for Molecular Engineering at the University of Chicago. There, my research focused on spin defects in silicon carbide and related hybrid systems for quantum information. 

My research has led to a patent application for technology related to charge conversion of defects in solid-state materials, and I have published more than 20 papers in high-impact journals.
