Quantum

As an integrated part of the Mobile Communications and Quantum Technologies Laboratory at the BME Department of Networked Systems and Services (BME HIT), we focus on quantum based communications and quantum information theory.

Our team has published scientific results in the field of quantum computation and communications, quantum cryptography and quantum information theory.

Our focus. Our main focus is on the following areas: theory of quantum computation and communication, quantum Shannon theory, quantum channel coding, quantum error correction, quantum cryptography, quantum repeaters, quantum networks, quantum space communications, visualizing multi-qubit systems using fractal representation, single photon based quantum key distribution, continuous variable quantum key distribution, entanglement based quantum key distribution, satellite based quantum communication, quantum random number generators.

Sándor Imre published his book “Quantum Computing and Communications” in 2005 by Wiley, and his second book with László Gyöngyösi entitled “Advanced Quantum Communications” (published by Wiley, 2012) which includes the most recent results of quantum communications and quantum information theory.

Awards. The scientific research of our members were recognized by the Gábor Dénes award (Sándor Imre, 2011), by the Csiby Soma scholarship (László Gyöngyösi, 2010), BME doctoral candidate scholarship (László Bacsárdi, 2009; László Gyöngyösi, 2011), by IAF Young Space Leadership Award (László Bacsárdi, 2017), by Puskás Tiavadar award (Eszter Udvary, 2016; László Bacsárdi, 2018), by Fonó Albert Award (László Bacsárdi, 2018). Sándor Imre has been elected as corresponding member of the Hungarian Academy of Sciences (2019), while László Bacsárdi has been elected as corresponding member of the International Academy of Astronautics (2019).

Education. We supervise M.Sc and B.Sc students and we have two courses on quantum communications: Introduction to Quantum Computing and Communications (BMEVIHIAV06, English in fall semester, Hungarian in spring semester) and Quantum Computing and Communications (BMEVIHIMA14).

Our former (non active) courses includes Quantum computing and communications (BMEVIHI9353 and BMEVIHISV53) as well as Quantum Infocommunications and Applications (BMEVIHIAV13).

Outreach. Besides our educational activity at the university, we carry out huge effort to popularize the quantum communications in Hungary. This includes scientific lecturers at different secondary schools and events, and writing Hungarian science articles.
