ISQA - Information Security in the Quantum Age

16-20 March 2020 Okinawa, Japan

Uncompromisable information security can be only achieved by relying on unshakeable scientific principles in mathematics or physics. It is therefore directly connected to progress in fundamental research in both of these area and requires constant progress to advance.

However, to translate these results into useable technology and to maintain everyday security within the current technology, is a just as important goal to achieve.

In alignment with the goal of the Government of Japan to put quantum cryptography into practical use from 2025, this meeting will bring together Japanese and international  forefront researchers in experimental and theoretical approaches, to discuss the current status, make valuable connections and outline required future progress.

The number of participants is limited to about 50.

Location: OIST Seaside House, Okinawa, Japan
