I am a theoretical physicist working at the interface of nuclear physics, particle physics, and astrophysics using tools from quantum information science.

The Brar group probes the electronic, magnetic, and optical behavior of materials at the atomic-scale in search of new phenomena that have both fundamental and technological importance.

The Choy group is interested in the development of quantum sensors (based on neutral atoms and atom-like systems in solids) for sensitive measurements of physical quantities such as inertial forces, magnetic fields, and time, as well as the application of nanoscale optics and photonics to improve the utility and performance of quantum instruments.

The research of our group spans many areas of heteroepitaxy of complex oxides and nanostructure fabrication, from thin film synthesis to characterization and device application of various novel materials. Our interest includes the synthesis and characterization of epitaxial oxide heterostructures and heterointerfaces uniquely suited for oxide nanoelectronics piezoelectric heterostructures for hyper-active MEMS/NEMS, ferroelectric and multiferroics for magnetoelectric and photovoltaic devices. Our interest also includes the epitaxial growth of ferronictide superconducting thin films and 2-dimensional electron gas at oxide hetero-interfaces.

The Eriksson Group studies quantum computing and information, with a special emphasis on semiconductor qubits in silicon and silicon-germanium, both on their own and coupled to superconducting waveguides and circuits. We use state-of-the-art clean-room processing techniques to nanofabricate these qubits, and we measure, characterize, and program the qubits using microwave electronics techniques at dilution refrigerator temperatures, which are as low as 10 mK. In addition to quantum computing, we study thermal transport in nanostructures and NV-centers for chemical sensing.

My research interests include the theory of solid state qubits, the optimization of qubit performance, and simulations of qubit devices and their evolution.

Our group believes that studying chemical and biophysical systems via single-molecule techniques is a profound and absolutely delightful way of doing science. We use single-molecule methods to study chemical reactions such as homogeneous catalysis, biophysical processes such as protein folding, and materials properties such as energetic disorder in photovoltaics. We build instruments, synthesize molecules, fabricate nanophotonic devices, and are trying to make some really exciting new measurements.

Our research is centered in the unique chemical and physical phenomena that occur at surfaces and interfaces of solid materials.

Our group creates novel software systems to simplify the building of performance-critical applications, such as electronic design automation (EDA), machine learning (ML), and quantum computing. Our software has been used by thousands of people in industry and academia.

The Jacobberger group develops scalable approaches to engineer low-dimensional (2D, 1D, and 0D) materials, heterostructures, assemblies, and devices with atomic-scale precision. We are particularly interested in single-photon emitters and spin defects in semiconductors, novel quantum phenomena in heterostructures, and molecular-based qubit systems.

My research is in Quantum Computing and Condensed Matter Theory. Presently, I am working on new forms of error correction involving 2-designs. I have a longstanding project on electromagnetic noise in quantum computers, particularly on the spatial correlations present in such noise. I am working improvements for the quantum adiabatic algorithm that involve the idea of catalysis. We have recently developed a theory of discrete scale invariance in Weyl semimetals and an explanation of the Kerr effect in unconventional superconductors.

The group of Prof. Mikhail Kats carries out experimental and theoretical research across the fields of optics and photonics, device physics, and nanoscale science. The primary goals of the group are to investigate fundamental problems in optics and photonics and to create next-generation optical components to emit, modulate, and detect light across the visible and infrared spectral ranges.

We use molecular beam epitaxy (MBE) to synthesize thin films and superlattices of Heusler compounds and engineer their electronic, magnetic, thermoelectric, topological, and mechanical properties.

Our group explores the interaction of charge carriers, lattice vibrations, and electromagnetic waves in nanoscale systems. Our research is theoretical in nature: we develop novel mathematical and computational techniques in order to simulate the exciting world at the nanoscale. We also collaborate with several excellent experimental groups.

My research is stimulated by the fascination for the collective many-body behavior of quantum particles and aims to uncover both fundamental physical phenomena and potential practical applications.

I am a condensed matter theorist with research interests in quantum kinetics, mesoscopic effects, nonequilibrium systems, superconductivity, and topological systems.

Superconducting integrated circuits are a leading candidate for the realization of quantum bits (“qubits”). We are focused on the development of technologies to enable scaling to quantum arrays comprising thousands or millions of qubits, as needed for robust quantum error correction. We have separate research efforts in the areas of quantum coherence, quantum measurement, and high-fidelity coherent control. In addition, we are working with collaborators to develop hybrid quantum systems that capitalize on the distinct strengths of disparate quantum technologies.

The Otten Lab’s goal is to accelerate the realization of useful, utility-scale quantum computers, networks, and sensors. We develop, analyze, and test quantum algorithms for applications in quantum chemistry, quantum dynamics, and quantum machine learning. Our team also focuses on creating and implementing quantum characterization, verification, and validation (QCVV) methods to understand and mitigate inevitable errors.

Dr. Ping is as associate professor in MSE and affiliated professor with Chemistry and Physics. Her research group focuses on developing and employing first-principles many-body theory and quantum dynamics for materials applications.

Our research group focuses on cradle-to-grave processing of 2d layered materials, both in bulk and in 2D – controlling the growth, heterostructure stacking, and fabrication processes with the primary goal to reveal and study sensitive quantum phenomena which are typically destroyed by disorder.

We are exploring the use of neutral atoms for quantum information processing using several related but complementary approaches. Experiments are underway with three different atomic species: Rb, Cs, and Ho.

The Soley Group pursues research at the intersection between chemistry, physics, applied mathematics, and computer science with a particular interest in ultracold chemistry and collisions, quantum computing algorithms, quantum reflection, and PT symmetry.

The Song group focuses on exploring novel 2D quantum materials and their van der Waals heterostructures. The group is particularly interested in studying exotic 2D magnetism, 2D superconductivity, and topology by using various techniques, such as nanodevice fabrication, magneto-optics, quantum transport, thermoelectrics, optoelectronics, optical spectroscopy and microscopy.

I study programming models and architectures for Quantum Computers. My research focuses on developing control architecture and software (programming models, interfaces, compilers) for quantum computing platforms. I am broadly interested in Computer Architecture, Quantum Computing, and Cryogenic Electronics.

Computational complexity theory and the theory of computing, in particular lower bounds for NP-hard problems, pseudorandomness and derandomization, and quantum computing.

My research focuses in the area of theoretical condensed matter physics. I study transport and non-equilibrium phenomena in quantum many particle systems, as well as the role of disorder and chaos in the quantum limit. My research is related to problems motivated by experimental investigation of mesoscopic and nanoscale electron systems and intended for future development of electronics and quantum information technologies.

We explore quantum materials/devices to solve the ground challenges in nano, energy, and information technologies. We also employ electronic, optical, and magnetic probes to understand materials/devices’ mechanisms and, in return, optimize performance.

My research focuses on the interplay of many-body, spin-orbit, valley, and g-factor physics of semiconductor quantum dots towards applications for spin qubits. I also research semiconductor-superconductor hybrids with an emphasis on the realization of topological superconductivity and Majorana zero modes for topological quantum computing.

Our group research focuses on the structure-property relationships and the light-matter interactions in quantum materials for high-performance computing, efficient energy conservation, and high-speed THz optoelectronics. In particular, we use ultrafast light pulses and electrically controllable nanodevices to discover, understand, and engineer emerging 2D quantum materials and their interfaces. We will both investigate fundamental physics and develop functional devices relying on quantum-mechanical effects including non-equilibrium phase transitions, quantum collective excitations, electronic/lattice many-body interactions, and photocarrier dynamics in energy conversion.

The Yavuz Lab is an experimental atomic physics group. We specialize in quantum optics and ultrafast physics.

Our research includes experimental, computational, and theoretical studies that seek to answer a variety of questions:

• Can we use visible light to produce or resolve sub-nanometer images?
• Can we engineer the index of refraction in an atomic system to produce interesting behavior like lossless index enhancement or a negative index?
• Can we exploit the interaction of light and molecules in order to efficiently turn one laser into dozens of coherent lasers?
• Can we construct a continuous-wave “white laser,” a broadband coherent light source capable of producing both sub-femtosecond pulses and arbitrary optical waveforms?
• Can we localize populations of atoms to regions much smaller than a diffraction-limited spot?

We investigate these and a variety of other problems in our two optics labs and through computer modeling.
