Seeking for quantum PhD students.
Are you a master/engineer student fascinated by quantum physics or future of quantum technologies? Want to run quantum computers, build quantum network, or encrypt quantum messages?. Interested to join our research team for four years of you life? That is the time it takes to do the research and become expert (with PhD title) in quantum simulations, or optical quantum communication networks, or quantum security, or foundations of quantum phenomena. All of these fields are waiting for your contribution. Currently, we have open several PhD positions at our Institute. We are open for submissions until 10/04/2022, exceptionally also later) with PhD starting in September 2022. If interested, as the first step, please get in contact with a potential PhD advisor (send him your cv, motivation letter and contacts to potential references), discuss the subject and follow his/her instructions. Do not wait until the submission deadline and do this as soon as possible. If you are uncertain who to contact, just choose any of us. We are all happy to help you to select your quantum destiny.

Experimental implementation of secure anonymous protocols on an eight-user quantum key distribution network
Anonymity in networked communication is vital for many privacy-preserving tasks. Secure key distribution alone is insufficient for high-security communications. Often, knowing who transmits a message to whom and when must also be kept hidden from an adversary. Here, we experimentally demonstrate five information-theoretically secure anonymity protocols on an eight user city-wide quantum network using polarisation entangled photon pairs. At the heart of these protocols is anonymous broadcasting, which is a cryptographic primitive that allows one user to reveal one bit of information while keeping their identity anonymous. For a network of n users, the protocols retain anonymity for the sender, given that no more than n − 2 users are colluding. This is an implementation of genuine multi-user cryptographic protocols beyond standard QKD. Our anonymous protocols enhance the functionality of any fully-connected Quantum Key Distribution network without trusted nodes.

Postdoc opening
We are seeking for postdocs in the area of quantum communication technologies. We are interested for candidates of experimental and theoretical background in the area of quantum communication engineering, or experimental quantum optics, or quantum information theory. The positions are offered for one year (extensions for couple of more years are possible, but details depend on the particular financial source) with a basic gross salary from 1800 eur/month and flexible expected start (earliest from June 2022). The application consists of CV (including list of publications), research statement (short summary of personal research interests and plans), and three names of potential referee we might ask for recommendation letters. Please send all this information to Mario Ziman by email (ziman@savba.sk) before 31/03/2022. Only complete applications will be considered.
