INAQT network meetings
First INAQT network in-person meeting - January 2023
The first in-person meeting of the INAQT network took place January 23rd - 25th 2023 in Glasgow at the Glasgow Grosvenor Hotel!
The main aim of the meeting was to strengthen the network, which consists of a small number of active experts in the field of indefinite causal order (ICO), and many newcomers, experts in various areas of quantum technologies and quantum optics. The format aimed to encourage meaningful interactions by dedicating time on extended focus talks from ICO experts, as well as invited talks and afternoons reserved for networking and poster sessions. The meeting ran over three days, each with a broad focus on a different aspect of ICO: foundations, implementations, and applications.
Recordings from the meeting are linked after each day of the 2023 programme below.
Second INAQT network in-person meeting - November 2024
Our next INAQT network meeting took place on November 4th - 6th 2024 in Vienna at the Erwin Schrödinger International Institute for Mathematical Physics.
We heard about visits supported by the network, and had a range of contributed talks and posters from network participants.
An outline of the event is detailed in the 2024 programme below.
