The quantum state over time is unique! Seokhyung and I developed a set of minimal and physically motivated axxioms, and from there were able to show that they pinpoint a single descriptions for our recent subject of fascination: QSOTs :) Check out our preprint arXiv: 2308.12752 for details!

Finally after 1.5 years of meeting weekly over Zoom, and a wonderful week in Hannover together, we completed our review on catalysis in quantum information theory! Patryk and Henrik were wonderful to work with, and I enjoyed our "catalyst fan club" gatherings very much! Check out our article on arXiv (arXiv:2306.00798) for a concise guide and a one-stop resource (pun intended) for anyone new to catalysis!

Exciting news! My second paper with Jeongrak is out. While tackling his first project, we couldn't resist pondering how catalysis might shake up the hierarchy of thermal processes, and the answer turned out to be delightfully straightforward! Dive into the fun details by checking out our paper on arXiv:2303.13020.

Seokhyung and I have always wondered about the cost of using a catalyst and retaining correlations with the systems it interacted with... in this work, we make rigorous the intuition that that such a catalyst would be unable to maintain any quantum correlations it initially had with other systems, shedding light on a subtle hidden cost.

I'm particularly proud of this work because it's the first project with my first PhD student Jeongrak Son :) Our journey began with the modest goal of exploring the advantages small catalysts could offer in the real-world context of ETOs. In the end, our most significant accomplishment was making analytical and technical strides in characterizing ETOs—an especially challenging problem. The impact was such that it spilled over into a follow-up project! Discover the details in our work on arXiv:2209.15213.
