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 has spanned many areas of heteroepitaxy of complex oxides and nanostructure fabrication, from thin film synthesis to characterization and device application of various novel materials. Many new electronic, magnetic and optical devices require sophisticated thin film structures or multilayers, which demand that the thickness be controlled down to one unit cell; other devices may need lateral dimensions to be patterned down to nanometer sizes. Complex oxide materials possess an enormous range of electrical, optical, and magnetic properties. For instance, insulators, high quality metals, dielectrics, ferroelectrics, piezoelectrics, semiconductors, ferromagnetics, transparent conductors, colossal magnetoresistance materials, superconductors, and nonlinear optic materials have all been produced using oxide materials. Therefore, thin films and heterostructures of oxide materials have great potential for novel device applications. A major challenge is to prepare these materials with epitaxial thin film form with atomic layer control and integrate them so that these properties can be fully utilized in electronic devices. 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.
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.
Research in the Kolkowitz lab focuses on metrology, tests of fundamental physics, and sensing using quantum systems. We are building some of the most precise clocks in the world and exploring novel applications of these amazing instruments. We are also developing new sensing techniques using atom-scale defects trapped inside diamond and applying them to study the origins of decoherence in quantum platforms.
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.

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.
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.
