Pioneer Symposia

2025 KPS Spring Meeting   April 23-25, 2025   Daejeon Convention Center 1

Pioneer symposia are consisted of several invited talks on hot issues of physics sub-fields. Each symposium is made in English and extends at least 2 sessions in a meeting. Symposium titles and organizers of pioneer symposia for upcoming meeting are as follows. E represents an ‘English session’ where all authors present in English.


1) E [Particles and Fields] Discovery of Quantum Entanglement in High Energy Physics

   Time/Room: October 24 (Thursday) 14:24 - 17:12 / Seminar Rm 1 

 

  [Organizers] KIM Taejeong (Hanyang Univ.), SHIN Seodong (Jeonbuk Univ.), GOH Junghwan (Kyunghee Univ.)
 

  [Invited Speakers]

Session Code: [F2-pa], October 24 (Thursday) 14:24 - 15:12

  • SIMPSON Ethan Lewis (University of Manchester, UK): “Entangled in Tops: How we turned ATLAS into the world’s largest quantum information experiment”

 

   [Scope]
Recently the quantum entanglement was discovered between pairs of top quarks for the first time by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC). The top quark pairs are produced at the center of mass energy of 13 TeV which is more than 12 orders of magnitude higher than typical energy for laboratory entanglement experiments. This discovery shows the quantum entanglement can also occur at the high energy scale and the LHC can also be used to study quantum mechanics and quantum information. We will discuss this discovery of quantum entanglement in high energy physics in this pioneer session.

   [Scope]
Quasiparticles in exotic materials create new types of quantum phenomena by complexly combining charge, spin, lattice, and orbital. To explore the exotic materials, not only cutting-edge analysis tools of charge and spin properties, but also accessibility to ultra-fast time scale in which the quantum phenomena occur are required. Moreover, advanced methodologies to grow quantum materials controlled at the atomic layer level and to interpret them theoretically become also important. This symposium aims to introduce the latest research trends in the field of condensed matter physics by introducing advanced studies on quantum matters.

   [Scope]
Due to the remarkable development of quantum information technology, control of individual quantum systems has reached a very high level.

It is important to take a look at practical semiconductor-based quantum technologies for hybrid quantum systems and interface research.
