Workshops and Conferences

### Theory of Quantum Computation, Communication and Cryptography (TQC2024)

#### September 9 - 13 2024, Okinawa, Japan

- The Theory of Quantum Computation, Communication and Cryptography (TQC) is a leading annual international conference for students and researchers working in the theoretical aspects of quantum information science. The scientific objective is to bring together the theoretical quantum information science community to present and discuss the latest advances in the field.

### Okinawa School in Physics: Coherent Quantum Dynamics

#### September 24 - October 4 2024, Okinawa, Japan

- The study of quantum coherent dynamics is currently one of the most active and exciting areas in physics. It holds the promise for the development of new technologies (quantum computing, quantum metrology,...) and, at the same time, has already delivered insights into the foundations of quantum mechanics. Its fast moving pace and new approach has attracted many young researchers and summer schools - at which leading experts share their knowledge and directly interact with the participants - have become an integral part of the community.
- The school will consist of lectures delivered by Japanese and international experts on the fundamentals of the area. These will be supplemented by accessible presentations (colloquia) on cutting-edge research problems. The topics are chosen to be deliberately broad and will give the students a wide perspective on different aspects.

### Quantum Extreme Universe: Matter, Information, and Gravity

#### October 21 - 25 2024, Okinawa, Japan

- Theoretical physics is often divided into different fields such as particle physics, condensed matter theory, and gravity, depending on the length scale of the logical targets. However, by introducing ideas from quantum information science into the physics of quantum many-body systems, and via their deep connections to quantum gravity, it is becoming clear that what underlies many of these theories is actually the same. This workshop aims to explore the quantum information theoretic connections between these various fields. In particular, we will focus on connections among quantum information, quantum gravity, and both theoretical and experimental quantum matter.
- This workshop will be held in collaboration between OIST and the MEXT-KAKENHI-Grant-in-Aid for Transformative Research Areas (A) funded “Extreme Universe (ExU)” consortium.
- Organizers:
- Aidan Chatwin-Davies (OIST, Qubits and Spacetime Unit)
- Philipp Höhn (OIST, Qubits and Spacetime Unit)

### From Quantum Materials to Quantum Information: Symposium on Trans-Scale Quantum Science and Quantum Materials Synthesis (QMQI2024)

#### November 11-15 2024, Okinawa, Japan

- The symposium "From Quantum Materials to Quantum Information: Symposium on Trans-Scale Quantum Science and Quantum Materials Synthesis" (QMQI 2024) is co-organized by OIST, the Quantum Materials Synthesis collaboration sponsored by the Gordon and Betty Moore Foundation, and the Trans-Scale Quantum Science Institute of the University of Tokyo. It will bring together researchers from quantum material science, quantum many-body physics, quantum computation, quantum information and foundations in a single event with the aim to exchange ideas at the interface of these disciplines and explore interdisciplinary research directions.
- Organizers:
- Collin Broholm (John Hopkins)
- Mingxuan Fu (The University of Tokyo)
- Philipp Höhn (OIST)
- Takeshi Kondo (The University of Tokyo)
- Mio Murao (The University of Tokyo)
- Satoru Nakatsuji (The University of Tokyo)

### Schrodinger Cats: the quest to find the edge of the quantum world

#### December 9 - 13 2024, Okinawa, Japan

- The generation of macroscopic quantum superpositions of massive objects have fascinated scientists since Schrodinger but scientific developments now promise that such superpositions may become possible in the very near future.
- This meeting will focus on the science of macroscopic quantum superpositions - or more commonly known as Schrodinger Cats. In the 1930s Erwin Schrodinger made a thought experiment to test the boundaries of quantum mechanics. He asked if it could be possible, not only in principle, but also in practice, to make a quantum superposition of a large-massive object (in his case a cat), in two very different positions. As far as we know - this should be possible - but extremely challenging experimentally. If one can even achieve this for nanometer (or larger), sized particles one opens the possibility of tackling many fundamental questions e.g. how does quantum interact with gravity, is there some other addition to quantum mechanics which prevents the formation of such large-massive quantum superpositions? Can such massive superpositions be used for ultrasensitive sensors.
- This meeting will bring experimentalists and theorists together to discuss recent science (experiment and theory), towards generating such quantum superpositions.
- This workshop is hosted by the Okinawa Institute of Science and Technology Graduate University, Japan supported by the EPSRC Project Levinet.
- Organizer:
- Kiyotaka Aikawa (Tokyo Institute of Technology, Tokyo, Japan)
- Sougato Bose (University College London, UK)
- Maria Fuwa (Gakushuin University, Tokyo, Japan)
- Yosuke Minowa (Kyoto University, Japan, from April 2024)
