Quantum Computing: From Research to Industry

Tuesday, February 27th, 2024 
11:00 – 13:00 (Sofia Time)

Organized jointly by NCC France and NCC Netherlands, this webinar aims to introduce the technologies of Quantum Computing and present the challenges and perspectives.

After an introduction, this webinar will address quantum gate-based computing, annealers, analog computing, and quantum simulation. French Ecosystem and the HQI program (France Hybrid HPC Quantum Initiative) which aims to provide free access to HPC-Quantum infrastructures for the needs of open, academic and industrial research, will be presented.

New article published using HPC-lab resources

Dr. Ivan Hristov and Dr. Radoslava Hristova  have revisited the problem of Three-body periodic collisionless equal-mass free-fall orbits,using high-accuracy numerical methods and a high-performance computer (Nestum cluster, Sofia Tech Park, Bulgaria http://hpc-lab.sofiatech.bg/) and have  found that(1) 15,738 i.c.s corresponding to 12,409 distinct solutions with T ∗ < 80. We use morerestrictive condition on the periods than Li and Liao: T < min(7, 80/|E|3/2).(2) When we apply time evolution of the (primary) i.c.s up to one half-period, we easily find8844 additional i.c.s., bringing the number of i.c.s up to 24,582. Some of the additionalorbits are ones that are missed by the search, but others are with T > 7 and T ∗ < 80.Therefore by applying this procedure we compensate to some extent that we use theless time consuming condition: T < min(7, 80/|E|3/2) instead of the ultimate one:T < 80/|E|3/2 . Now only 236 solutions (∼ 2%) are identified as self-dual, whichcontrast to the large number ∼ 43% of Li and Liao.(3) Certain partitioning of i.c.s within Agekyan–Anosova domain D, which are in agreementwith Tanikawa et al.’s division of D by 3-cylinders and 4-cylinders.(4) Distinct upper and lower bounds on the periods of orbits as (linear) functions of the length of symbolic sequence (word length)

The HPC laboratory is always  happy to support the high-level fundamental research!

Thrace Engineering Group visit

10:00 – 11:00

The Thrace Engineering Group representatives visited the HPC lab to discuss projects of mutual interest in the field of sensors design. Financing from an international research agency is discussed. The University of Sofia, Faculty of Physics will be a partner as well.

HPC-lab visit on 7.02.2024


The HPC lab was visited by Dr. K.Kostov, a former researcher at the University of Chicago, who currently is investing in spin-off companies. Possibilities for using the HPC lab resources for training physical chemists working for pharmacy were in the focus.

HPC lab visited by Mr. Andonov – FUJITSU-BULGARIA

Date: 17.01.2024

Time: 16:30 – 18:00

The focus of the meeting was  the upgrade of the NESTUM HPC cluster (FUJITSU based).
Mr. Andonov also informed the HPC team about the Fujitsu  technology to automatically generate new AI solutions specific to customers’ business needs.It has been decided to organise a seminar in the HPC lab – Sofia Tech Park on the topic. The exact date in February 2024  will be announced soon.

EUMaster4HPC related visit by an expert in Quantum Computing

Date: 22.01.2024
Time: 13:30 – 16:30

The HPC lab team discusses the involvement of the VGG-Consulting (V. G. Gueorguiev, Ph.D.) in the EUMaster4HPC
program as a mentor of the masters enrolled in the HPC program (Sofia University, University of Luxembourg)

Dr. Gueorguiev has been a Quantum Computing Mentor at the Quantum Open Source Foundation and the QWorld summer QIntern programs.
Dr. V. Gueorguiev is currently affiliated with the Ronin Institute, NJ, USA and the Institute for Advanced Physical Studies, Sofia, Bulgaria.
He does research in Nuclear Physics, Theoretical Physics, and Mathematical Physics.
