Quantum Information and Technology

The basis for quantum information and technology is quantum physics, the most accurately tested scientific theory. Remarkable technologies have been created with it, like the transistor and the laser, which, in time, have reshaped human culture. Quantum technology is now emerging in many new forms: quantum computing that may take us beyond Moore’s Law, quantum cryptography that promises “unhackable” communications, and ultra-sensitive devices to detect biological and chemical changes. New quantum algorithms promise to solve previously intractable computational problems and revolutionize simulation. From a device perspective, spintronic transistors, memories, and opto-electronic devices may replace their charge-based counterparts, leading to a new class of more powerful and energy efficient devices.

The University of Chicago is at the forefront of the fields of quantum science and engineering, featuring faculty members across multiple departments and institutes, including the IME, the James Franck Institute (JFI), the Department of Physics, and the Department of Chemistry. Below are some of the key contributors and their research focus, as related to quantum technologies.

David Awschalom

The Awschalom group has active research activities in optical and magnetic interactions in semiconductor quantum structures, spin dynamics and coherence in condensed matter systems (“spintronics”), macroscopic quantum phenomena in nanometer-scale magnets, and implementations of quantum information and sensing in the solid state.

Andrew Cleland

The Cleland group pursues research in the quantum-limited behavior of electronic and mechanical systems. Specific research topics include quantum integrated circuits based on Josephson junctions, nanomechanical and optomechanical resonators, quantum control of individual phonons and photons, and microfluidic-based electronic biosensing of cells and molecules.

Aashish Clerk

The Clerk group is broadly interested in developing a theoretical understanding of phenomena in driven-dissipative quantum systems, with a particular focus on superconducting quantum circuits, quantum optomechanical systems, and quantum electronic transport. The group has close collaborations with a number of leading experimental groups.

Greg Engel (IME Fellow)

The Engel group focuses on new strategies to observe, measure, and control excited state reactivity. Using spectrometers of their own design, they explore bio-inspired design principles for steering excitonic transport, open quantum dynamics, and photochemical reaction dynamics.

Giulia Galli

The Galli group is studying spin defects in wide-band gap semiconductors, in search of promising systems for the realization of quantum bits, or qubits, in solid-state environments. The current focus is on carbide and nitride materials.

Supratik Guha

The Guha group conducts research on new semiconductors and oxide materials and devices for new computing architectures, cyberphysical sensing systems, and energy conversion technologies. They are particularly interested in the discovery of thin film materials and novel devices that can be used for ultra-low power non Boolean computing and sensing.

Alexander High

Research at the interface of quantum optics, metamaterials, nano-photonics, and excitonics. Interested in integrating techniques of quantum optics with emerging metasurface technology to develop energy efficient, on-chip, and active control of the flow of light down to the single photon level. Also interested in exploring exotic light-matter states in solid-state systems, both to elucidate the physical properties of these states as well as utilize these states in the development of new technologies.

Jiwoong Park

The Park group’s research interest is to develop an experimental platform that investigates electrical, optical and thermal properties of individual nanostructures and their assembly with an ultrahigh spatial, temporal and energy resolution. In particular, they are most interested in interrogating how the dynamics of fundamental physical quanta – photons, electrons and phonons are intertwined in complex nanoscale materials, while exploring advanced nanoscale device configurations that fully utilize the interplay among different physical processes.

David Schuster (IME Fellow)

The Schuster group’s main areas of research include: 1) experimental aspects of quantum information and quantum control and 2) hybrid quantum systems using superconducting circuits to interface with other quantum degrees of freedom.

Jonathan Simon (IME Fellow)

The Simon group focuses on realizations of strongly interaction quantum materials composed of cold and ultracold atoms. Primary projects include: 1) Long-range interacting Rydberg polaritons realized in a high-finesse optical resonator and probed with single polariton-resolution, 2) Topologically Insulating Quantum Circuits, and 3) Double-Resonator Optical-Microwave Hybrid Quantum State Manipulator.

Tian Zhong

The Zhong lab focuses on developing enabling nanoscale photonic and molecular (e.g. rare-earth-ion doped crystals) technologies for building quantum hardware to realize an efficient, scalable Quantum Internet.
