buona serata,
I hope you are well!
tomorrow, there will be two presentations by our guest veronika baumann
from iqoqi and tu vienna. the first one will be at 11:00 in the fifth
floor's
meeting room, and the second at 16:00 in the interior court if weather
permits.
hope to see you all tomorrow!

Title: Different perspectives in (non)-causal quantum processes processes
Abstract: The process matrix framework was developed to allow for scenarios
with indefinite or quantum causal order, a phenomenon that is expected
to be
relevant for quantum gravity. A popular approach towards a quantum
theory of
gravity is the Page-Wootters formalism, which describes time-evolution
of systems
via correlations between a clock system and other quantum systems
encoded in
history states. We combined the process matrix framework with a
generalization
of the Page-Wootters formalism with multiple clocks. Each of these
clocks can
be thought of as corresponding to an agent and conditioning on a certain
clock
gives the respective agent’s perspective inside an a priori general
quantum process.
We implemented scenarios where different definite causal orders are
coherently
controlled and explain why certain non-causal processes might not be
compatible
with this framework.
