Tenzin Rabga is a researcher at SNU working at the intersection of atomic physics and quantum computation.

What is your current research? My current research concerns the development of a neutral-atom-based quantum computing platform. Quantum computing is a new framework for computing that leverages the fundamental quantum nature of our Universe. While physicists have long believed that such a platform could significantly surpass our existing computing capabilities, only recently, within the last decade or so, we have begun seeing the advancements in the practical tools needed to implement such a machine. Of the many systems at our disposal for building such a computer, our group is interested in the opportunities presented by neutral atoms, whose innate quantum properties make them natural candidates for qubits. In particular, we wish to explore the advantages of incorporating two different types of atoms in a single machine. To accomplish this, we will rely on tried-and-tested tools and techniques in atomic physics. We will begin by preparing cold samples of atoms using laser cooling and trapping. In fact, we routinely make samples with temperatures less than a millionth of a kelvin above absolute zero in our labs. We will then isolate individual atoms using optical tweezers – which are highly focused laser beams with waists less than a micron – for creating large and arbitrary arrays of single atoms. And finally, using the long-range interactions between atoms in their highly excited “Rydberg” states, we will dynamically tune the interatomic interactions and generate multiparticle entanglement – a key ingredient necessary for implementing universal computation. Once we demonstrate these single-species capabilities, we will turn towards dual-species operation. While single-species machines, with hundreds of high-fidelity qubits in large 2D arrays, continue to define the cutting-edge of neutral-atom-based machines, dual-species systems promise new capabilities, such as, novel ways for detecting and mitigating computational errors. With our research, we hope to complement and contribute to this global effort towards realizing practical quantum computers. What drew you to this work? I have always been fascinated by the foundational questions in physics. For instance, that quantum mechanics is on the one hand the most precisely tested physical theory we have, and on the other, may be the least understood and probably the one most plagued by deep philosophical issues is a very puzzling, yet exciting predicament to be in. Moreover, from studying the violations of fundamental symmetries of nature during my PhD to probing the macroscopic manifestations of quantum properties of matter in degenerate quantum gases during the later years, I have come to appreciate the tremendous access atomic systems provide in probing some of these questions. In that sense, this excursion into the field of quantum computing seems to me to be a natural continuation of this exploration, as I combine my passion for atoms and lasers with my fascination with the mysteries of quantum mechanics. What are you doing when you are not doing physics? Beyond the lab and raising my kids, I am either – if weather permits – up on a mountain somewhere around Seoul, or in a café somewhere poring over a philosophy book. While I dabble in both western and eastern philosophies alike, recently, I have been enjoying studying and thinking about ideas at the heart of Buddhist philosophy. When around like-minded folks, I also enjoy talking about philosophy, particularly about issues in philosophy of science and delving into the philosophical difficulties at the foundations of quantum theory. I find that just as my scientific background informs my philosophical inclinations, my philosophical adventures fuel my scientific curiosity.

I am interested in solid-state quantum light sources. Quantum emitters in two-dimensional materials have the potential to revolutionize our communication and information system.

What is your current research? My research focuses on discovering and engineering single-photon emitters in two-dimensional (2D) materials. In our lab, we study atomically thin crystals—often just one layer, or only a few atomic layers, thick. Using various methods, we create local defect states within these thin flakes that emit light exactly one photon at a time. We then identify these emitters, align our laser systems, and conduct optical measurements to characterize their properties. The fundamental work of identifying and controlling these single-photon emitters is a crucial building block for scalable quantum information science. Isn't it remarkable that, in theory, we can create a completely secure communication system using single photon emitters? To make this a reality, we strive to reliably generate and manipulate these single photons in a solid-state platform in a desired way to accomplish practical quantum communication. Therefore, we focus on understanding the various physical characteristics of these defects and uncovering their exact origins. It has the potential to revolutionize how we transmit and process quantum information, paving the way for advanced quantum optical networks. What drew you to this work? My fascination with this field grew from a deep interest in the potential of quantum computing and quantum information science. I was captivated by the idea that encoding information into fundamental quantum states could completely shift the paradigm of computation and secure communication. However, realizing this futuristic vision requires robust and scalable physical hardware. While exploring various quantum platforms, I was introduced to the world of 2D materials and solid-state quantum optics. The realization that we could generate actual quantum phenomena, like single-photon emission, just by manipulating the physical structure of an atomically thin material was incredibly intriguing to me. I was drawn to this work because it perfectly bridges theoretical world of quantum information with the tangible reality of materials science and optics. This is what drives my research forward. What are you doing when you are not doing physics? When I am not in the lab, I dedicate my time to weight training, running, and swimming. Experimental physics can be incredibly demanding, and experiments often do not go as planned. When I hit a wall in my research, physical exercise is my way of relieving stress and refreshing. It clears my mind and gives me the stamina to solve complex problems again. Besides staying active, I am an avid music enthusiast. I listen to almost all genres, but my true passion lies in exploring historically and critically acclaimed music, the kind of albums you might find highly rated on reviewing platforms. Taking the time to actively listen to albums, dissecting their layers, and understanding their context in music history is surprisingly similar to the scientific process. You know, discovering great music is always exciting.

  I work on hybrid quantum devices that combine semiconductor quantum dot qubits with superconducting resonators on the same chip. By integrating these two systems we aim to enable interactions between quantum dots and microwave resonators. My research mainly focuses on fabricating these devices and investigating how we can use this coupling to our advantage. What is your current research? I am working on hybrid systems consisting of semiconductor quantum dot qubits and superconducting resonators. Normally, these two systems are made separately and are basically separate research fields, but part of the motivation for my work comes from the fact that these two systems require very similar environments and measurement setups. They both need to operate in extremely cold environments, ideally inside a dilution refrigerator at millikelvin temperatures. They also both require very fast and precise electronics that can operate up to the few tens of gigahertz range, and they both rely on pulse control. So we need electronics capable of generating pulses with extremely fine temporal resolution. In other words, the electronic infrastructure required to measure and control these systems is very similar. What I do is essentially integrate both systems onto the same chip. We use a silicon-germanium heterostructure and fabricate quantum dots on it. After that, we fabricate aluminum superconducting resonators on the same device. These two systems are then coupled together through what we call galvanic coupling, which simply means that the metals are physically connected. Specifically, the end of the resonator corresponding to the voltage antinode — the point where the voltage amplitude is maximal — is connected to one of the plunger gates, which is the primary gate used to control the quantum dot. By doing this, we can create coupling between the resonator mode and the quantum dot qubit. So overall, my work focuses on fabricating these hybrid devices, measuring them, and trying to make this coupling work effectively. What drew you to this work? When I was an undergraduate student, I had the chance to attend one of the annual conferences of the Korean Physical Society. There, I listened to a talk by Junhee Choi, who at the time I think was still a postdoctoral researcher, but is now a professor at Stanford University. He explained his work on neutral atoms — I think specifically Rydberg atoms — and described how they trapped these atoms and applied very complicated pulse sequences. He showed how, by carefully controlling these pulses, they could effectively turn the atoms into qubits, or two-level systems, which we had learned about throughout our quantum physics courses. What really amazed me was how difficult it is in the real world to isolate and control such ideal two-level systems. Listening to that talk made me feel that I also wanted to become part of this growing movement toward building qubits and quantum devices. It seemed incredibly exciting. For some reason, just seeing how complicated the pulse algorithms and sequences were made the work feel fascinating to me. I wanted to challenge myself and put my own effort and creativity into that kind of research. It was a brief moment, but fortunately it stayed with me. And now, I find myself doing work that is actually quite similar to what I saw in that talk. That was really how everything started for me. What are you doing when you are not doing physics? I’ve always enjoyed being active and spending time outdoors, so one of my biggest hobbies is sports and exercise. I love playing sports like basketball and football, and I also enjoy going to the gym. I’ve been working out for quite a long time, although unfortunately not as much these days because the PhD has been taking up most of my time. Still, exercising and being active outside is something I really enjoy.]]> Thu, 14 May 2026 15:52:13 +0000 <![CDATA[Interview with Yong-il Shin: Understanding the Rules of Complex Quantum Systems with Ultracold Atoms]]>     Yong-il Shin I am a professor of physics at Seoul National University, where I lead the Quantum Gas Laboratory, and a member of the NextQuantum. My research focuses on experimental studies of quantum many-body systems using ultracold atomic gases, with emphasis on nonequilibrium dynamics, quantum turbulence, and strongly interacting quantum matter. Through highly controllable atomic platforms, my group aims to bridge fundamental quantum physics and emerging applications in quantum simulation and information processing.       Interview | 1. Current research topic and overview My research explores how complex behavior emerges in quantum systems using ultracold atomic gases. In these experiments, atoms are cooled to nano-Kelvin temperatures, where thermal motion is nearly frozen and quantum effects dominate. Using laser light and magnetic fields, we create quantum gases as clean model systems for many-body physics. A central theme is nonequilibrium quantum dynamics—how systems evolve when driven away from equilibrium, including turbulence, collective motion, and phase transitions. A recent focus is the study of superfluid phase transition dynamics in strongly interacting Fermi gases. When driven across a transition, the system cannot respond instantaneously, leading to defect formation via spontaneous symmetry breaking. We study this within the Kibble–Zurek framework, which predicts universal scaling laws linking defect density to the transition rate. In parallel, we investigate quantum turbulence in Bose–Einstein condensates. More broadly, we aim to understand how energy, correlations, and structure evolve in quantum many-body systems far from equilibrium, and we are extending these studies to programmable platforms using optical lattices and atom arrays. 2. Significance and future plans This research addresses how simple quantum rules give rise to complex collective behavior. Nonequilibrium processes—such as phase transitions, transport, and turbulence—are widespread yet difficult to describe, particularly in quantum regimes. Ultracold gases provide a uniquely clean and tunable environment to study these phenomena. Our work on phase transitions and Kibble–Zurek scaling highlights universal dynamics across systems ranging from condensed matter to cosmology, while also informing coherence and stability in quantum technologies. Looking ahead, I aim to connect these studies to new computational paradigms. In hybrid quantum computing, quantum systems act not only as digital processors but also as dynamical resources. For example, quantum reservoir computing harnesses intrinsic many-body dynamics for information processing, with classical systems handling training and readout. Similarly, quantum chaos offers potential for sampling and optimization tasks. By developing programmable neutral-atom platforms, we aim to create systems that both simulate complex quantum phenomena and perform computational tasks, using controlled quantum dynamics as a resource. 3. Key considerations and personal perspectives A guiding principle in my research is to identify simple, universal descriptions of complex phenomena. I focus on measurable quantities—such as scaling laws and dimensionless parameters—that reveal underlying order. Equally important is controllability and interpretability. Nonequilibrium systems exhibit rich dynamics, but reliable insight requires carefully designed experiments and clear reference points. I am particularly interested in interdisciplinary connections, where ideas from quantum physics, statistical mechanics, and information science intersect. This perspective naturally connects to hybrid quantum computing and chaos-based information processing. I believe future advances in quantum science will come from integrating multiple approaches, where complex quantum systems serve both as objects of study and as functional computational resources.]]> Thu, 14 May 2026 15:35:01 +0000 <![CDATA[Conversations with NextQuantum Scientists: Tenzin Rabga, Jeonghan Lee, Seungbum Woo]]>
