Principal investigator

Prof. Kater Murch

2008 Ph.D., University of California, Berkeley
2007 MA, University of California, Berkeley
1998 BA, Reed College

Professional History
2013-present Assistant Professor, Washington University
2008-2013 Postdoctoral Scholar, University of California, Berkeley

Kater received his B.A. in physics from Reed College in 2002. After that, he spent a long year slacking off, working as a bee keeper, honing his guitar skills, and studying the cello before finally starting his Ph.D. work at UC Berkeley with Prof. Dan Stamper-Kurn. After some time studying Bose-Einstein condensation in multiply connected geometries, Kater focused his interests on general problems in quantum measurement, and performed some of the first studies of position measurement quantum backaction. After receiving his Ph.D. in 2008, Kater continued work in the Stamper-Kurn group studying a possible super-solid phase of matter which occurs in spinor-Bose-Einsten condensates, and constructing a state of the art BEC apparatus. After a short postdoc in the Stamper-Kurn Group, Kater joined Irfan Siddiqi's group to study superconducting quantum circuits, where he continued to study basic questions in quantum measurement and quantum noise. In 2013, Kater joined the faculty at Washington University. In 2015 Kater received the Alfred P. Sloan Fellowship in Physics.

Mahdi Naghiloo

I got my B.Sc in solid state physics from the University of Zanjan (ZNU) near my hometown Hidaj. For my master degree, I studied quantum optics at Sharif University of Technology (SUT), Tehran, Iran. I moved to the US in 2013 to start my Ph.D. study in Murch Lab, Washington University. Here I got my hands dirty with several experiments on quantum physics with superconducting circuits, exploring fundamental *problems* in the quantum world. I mostly focus on measurement dynamics, quantum thermodynamics, and aspects of metrology with quantum circuits. Our main tool for these studies is a technique called "weak measurement" by which we can continuously monitor the evolution of a single qubit without collapsing the quantum wavefunction.

Patrick Harrington

After completing my B.Sc. in Physics at Gordon College (north of Boston) and a researching laser spectroscopy with Thermo Fisher Scientific for a year, I joined the Murch group here at Washington University as a graduate student. Throughout my PhD, I have focused on open quantum systems with experiments on superconducting circuits. I look to explore the physics of open quantum systems with bath engineering methods, where dynamics ensue from drive and dissipation consequent of specifically tailored interactions between a quantum circuit and its electromagnetic environment. Apart from these research interests, I enjoy long treks, making music, and bantering.

Jonathan Monroe

Howdy! I graduated from Texas A&M University where I did a little bit of everything that I could. I graduated with a B.Sc. in physics, a B.A. math, and minors in computer science and astrophysics. My main research at the time was investigating how galactic environments changed the way galaxies grow. Now in the Murch Lab I'm doing something a bit different by studying how concepts from thermodynamics extend to the quantum regime. I ultimately aim to develop better quantum computing protocols through a thorough understanding of quantum measurement. When I'm not in the lab I love playing ultimate frisbee, facing the outdoors, and talking philosophy.

Taeho Lee

I am from Seoul, South Korea. I finished my undergraduate in Nanoscience from Chiba University in Chiba, Japan. For my master's degree, I studied nano-photonics in the field of Applied Physics by developing Raman microscopy at Osaka University in Osaka, Japan. I moved to St. Louis to start my Ph.D. in August 2017 and joined the Murch group at Washington University in St. Louis. Here, I am investigating entropic uncertainty relations in quantum measurement. I also focus on e-beam fabrication of superconducting quantum circuits to further explore the quantum world. In my free time, I like to study French and Mandarin and watch major league baseball.

Maryam Abbasi

I did my undergrad and master in physics at Ferdowsi University of Mashhad, Iran. My master's degree was focused on Ads/CFT correspondence, more specifically on holographic entanglement entropy. I joined Murch lab in the summer of 2018. Currently, I am working on non-hermitian systems and also exploring potential setups for designing a "giant atom" in a circuit QED setup.

Wolfgang Zober

I graduated from Wheeling Jesuit University (in northern WV) with a B.Sc. in Physics and Mathematics and a minor in theology. As an undergraduate, I was involved in a range of projects. For physics, my main project was an internship at NASA Goddard Space Flight Center where I worked in the laser and electronic optics group designing a laser for sodium LIDAR. In mathematics, I did statistical analysis of euchre, a regional card game. In the Murch lab I am currently working with nitrogen vacancies in diamond as a room temperature quantum system. In my spare time I participate in intramural sports, do nature photography, and play music.

Xingrui Song

I am from Zhejiang province, China. I graduated from the School of the Gifted Young (SCGY) of University of Science and Technology of China (USTC) with a B.Sc. degree in Atomic & Molecular Physics. During my undergraduate years, I studied PT-symmetric Hamiltonians in CAS Key Laboratory of Microscale Magnetic Resonance. I spent my summer of 2017 at Texas A&M University numerically investigating partial differential equations derived from a newly proposed gravity theory. Quantum mechanics is amazing. I am interested in almost every aspect of quantum mechanics, from quantum information to quantum gravity, because I believe they are mutually connected. In the Murch lab, I am currently working on a project in quantum thermodynamics. I am also interested in the promising technologies of quantum computation as well as artificial intelligence.
