About the Course

The main focus of this school is quantum communications ranging from quantum key distribution (the most advanced quantum technology) to quantum internet (the future quantum platform). This fields involves security technology, cryptography, post-quantum crypto, entanglement engineering, quantum optics, quantum memory, quantum solid state physics, ion traps, quantum protocols, quantum evaluation theory, quantum networks, etc. This field has yet not attracted the same attention for quantum computation, however the future impact of the science and technology from quantum communications will be important to integrate various quantum and classical technologies. We aim to grow a research community in this field to advance these emerging science and technology.

This topic is truly interdisciplinary, being relevant to researchers in physics, mathematics, computer science, and communication engineering. We welcome participants from all these different fields!

SIP Industry Days and SIP Industry Session

SIP stands for the Cross-ministerial Strategic Innovation Promotion Program. It is a national program in Japan led by the Council for Science, Technology and Innovation (CSTI) of the Japanese government, with interdisciplinary management aimed at realizing scientific and technological innovation in the country. OIST participates in the “SIP3 Quantum” theme of this program.

During OSP2025, the first two days are designated as the “SIP Industry Days.” The purpose of this event is to promote networking between international and domestic academic participants and representatives from domestic industry. The event also provides opportunities for academic participants to learn more about research and collaboration opportunities at domestic companies. In addition, domestic companies will have the chance to showcase their work during the poster session, highlighting their research, potential collaborations, and career opportunities.

On Tuesday, September 22, 2025 SIP Industry Session will be held.

Topical Research Talks:

  • Nikita Astrakhantsev - Google Quantum AI (USA) - Benchmarking high-fidelity computationally-complex quantum dynamics on a 69-qubit Sycamore chip
  • Koji Azuma - NTT Basic Research Laboratories (Japan) - Towards a quantum internet

Pitch Talks:

  • Chihiro Dogo, KDDI Research, Inc. (Japan)
  • Naoki Takekoshi, IHI Corporation (Japan)
  • Kaori Tanaka, Strangeworks, Inc. (Japan)

A lot of international airlines fly to Japan and onwards to Okinawa. Some international airlines also fly directly to Okinawa from other airports in Asia. We only provide accommodation in shared twin rooms. Please note that if you want to arrange your own accommodation, you will also have to arrange your own daily transport.

CURRENCY EXCHANGE
Bureau de Change: Very limited currency exchange service available at  Naha airport and none near OIST. Money exchange in your country or at major airports (Narita/Kansai/Nagoya) is strongly advised.
ATMs: ATMs for credit card cashing are available in Naha Airport or nearby post offices/ some convenience stores. Please be advised that some credit cards might not be accepted due to credit card policy.

CLIMATE
Average temperature around this time of the year is 25-30 Celsius. The weather in September will be hot and humid.

CLOTHES
OIST workshops are informal (no suit and tie required), so please feel free to dress casually and travel light.

ELECTRICITY
The AC outlet in Japan is 100 V and fits plugs with two parallel blades (Type A, similar to USA). Please check if the AC adapter of your laptop is compatible with Japanese style and bring a plug adapter or a voltage converter if necessary.

FACILITIES OF SEASIDE HOUSE

  • Internet: WiFi available in public space. Wired LAN is available in guest rooms.
  • Amenities: Shampoo and conditioner, body soap, hair dryer and room slippers.
  • Laundry rooms: equipped with washer-dryers, detergent and ironing board sets.
  • Phones: Public phone available in the lobby area. Calling card is required to make a domestic/international phone call. You may wish to purchase international calling cards at major airports as they are not provided at Seaside House. Some credit cards work by entering your credit card numbers and PIN code. Phone equipped in each guest room is for in-house calls only.

Code of Conduct for OIST Workshops

Purpose
To ensure that all participants have a clear understanding of the behavior that is expected of them.

Code of Conduct
We are committed to making our workshops (workshop(s) organized by OIST, hereinafter “our workshop(s)”) an inclusive space for sharing ideas and knowledge. We will not tolerate disrespectful communication, discrimination, harassment, or bullying in any form. As such, all participants attending our workshops are required to comply with this Code of Conduct. To provide all participants the opportunity to benefit from our workshops, we at OIST are dedicated to a positive, safe and harassment-free experience. Harassment in any form is specifically prohibited.

What is Harassment?
Harassment involves continued antisocial or unreasonable actions that violate a reasonable person’s personal rights and/or dignity and cause mental suffering, and thus worsen the person’s environment or make him/her anxious about participation. Behavior that is acceptable to one person may not be acceptable to another, so we ask that you use discretion to be sure that respect is communicated. Harassment intended in a joking manner nevertheless constitutes unacceptable behavior. Speech that is not welcomed or that is personally offensive, whether it is based on gender, age, sexual orientation, mental or physical disability, ethnicity, national origin, religion etc. will not be tolerated.

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please bring this to the immediate attention of the organizers. If you wish to report an issue concerning the organizers, you can contact the Conference and Workshop Section directly and submit a confidential report by sending an email to workshop-codeofconduct@oist.jp (use the provided Report Form Template to submit your report. You can attach other type of files to the email if necessary).

All complaints will be taken seriously and responded to by the Dean of Research promptly. Confidentiality will be maintained to the extent that it does not compromise the rights of others. Individuals found in breach of this Code of Conduct will be dismissed from the workshop immediately. Retaliation for reporting harassment is also a violation of Code of Conduct, as is reporting an incident in bad faith.
