Your experience
Smolenice Castle
The school will be held at the Smolenice Castle, history of which dates back to 15th century and which currently serves as the Congress Center of Slovak Academy of Sciences. It is situated approximately 60 km northeast from Bratislava in the central area of the smallest Slovak mountain chain called Malé Karpaty.
More information is available at the official Congress Centre website.
ACCOMMODATION
Provided inside the castle. Let us stress that it is included in the conference fee so you do no have to make any reservation by yourself.
INTERNET
Yes. The castle area is covered by a free wi-fi signal. Details will be given at the meeting.
Smolenice Castle
After a successfull QUAPITAL summer school in 2019, we would like to build a tradition of hosting yearly quantum communication summer schools.
QUAPITAL is a consortium of hosting providers to build the first reliable Quantum Internet on top of Europe’s glass fiber network.
The Institute of Physics SAS acknowledges the summer school’s financial support via the subcontracting project QUAPITAL.SK (OPENQKD Contract Number 857156 — Search for Subcontractors, Open Call 2).
