The event is co-hosted by the QTX research forum led by Alexander Ling of NUS and Markus Krutzik of Humboldt-Universität zu Berlin and Ferdinand-Braun-Institut, Leibnizinstitut für Höchstfrequenztechnik. The forum has previously met in Singapore (2018), Germany (2018), UK (2019), and online (2020, 2021).

After last year's successful virtual QTX-5 workshop, we are meeting again in person for the next "quantum technologies on small satellites QTX-6 workshop" on 26-27 September in Singapore!

We are planning a two-day event that will focus on (small) satellite technologies and quantum experiments in space - from components to missions. The workshop also includes a visit to Singaporean space start-up SpeQtral (https://speqtral.space/).
