Accepted posters TQC 2024
There are 429 accepted posters for TQC 2024. Of these, the Programme Committee highlighted 19 Outstanding Posters: you can find them by filtering on the dropdown tag menu below.
Clarifications
Accepted does not mean presented: Note that not all accepted posters will be presented at the conference due to author availability constraints. Shortly before the conference start, we will clarify which posters are set to be presented in person, based on whether the authors have registered for the conference. If you are interested in a particular poster, please contact the author directly.
Online presentation: For authors who cannot make it to the conference, it will be possible to present the poster online throughout the week on our Discord server. We will share instructions closer to the conference. In our experience, online attendance of these presentations is much lower than in-person attendance.
Withdrawing poster: If you cannot or do not wish to present your accepted poster, you don’t need to contact the organizers or PC chairs; this list will stay here to mark all submissions that were accepted. Exception: if you found a fatal mistake in the submission or would like to change the authors’ names, please let us know.
Upload media: If you would like to upload a thumbnail, more links or the poster pdf, please follow the link on the notification email sent by the PC chairs to the corresponding authors.
Poster sessions: The live poster sessions will be on Monday and Thursday (see schedule). If your poster submission number is below 290, you present on Monday; if it is above 290, you present on Thursday (290 is a talk). If you cannot make it to your allocated session, just bring the poster to the other session and find a free slot. You don’t need to ask the organizers.
Poster printing and size: The poster size should be A0 (84.1 cm × 118.9 cm) in portrait orientation. We recommend bringing your poster with you, as printing options in Okinawa are limited.

Equivalence between operator spreading and information propagation Poster

@Poster{P24_544,
title = {Equivalence between operator spreading and information propagation},
author = {Cheng Shang and Hayato Kinkawa and Tomotaka Kuwahara},
year = {2024},
date = {2024-01-01},
abstract = {A critical and unresolved problem in information science is: What are the precise limits of quantum communication? Dr. T. Kuwahara and I are curious whether this challenge can be solved through the powerful techniques of operator spreading. In 1972, the concept of the Lieb-Robinson bound was proposed, defining the maximum propagation of any information inside quantum many-body systems. This principle, intimately linked to the spreading of operators, finds extensive application in areas such as quantum simulation and information scrambling. On the other hand, the Holevo capacity characterizes the maximum amount of classical information that can be transferred through a quantum channel. In this poster, Dr. T. Kuwahara and I first established the general connection between the Holevo capacity and the Lieb-Robinson bound. We first provided the rigorous conditions under which operator spreading is equivalent to information propagation. We then provided two generalized theorems for the limits of quantum communication as long as unitary time evolution is satisfied. Theorem one universally gives strict upper and lower bounds on the amount of classical information over a quantum channel. Theorem two generalized shows rigorous upper and lower bounds on the entanglement capacity, which is the quantum information theoretic counterpart of heat capacity. Moving forward, we intend to extend our findings to open systems and explore the complexity of quantum dissipative dynamics from an information-theoretic lens.},
