Kvantové technológie na Slovensku
Kvantový flagship je dnes jednou z hlavných výskumných priorít Európskej komisie, ktorého cieľom je podpora európskeho výskumu v oblasti tzv. kvantových technológií. Vedná oblasť kvantovej teórie informácie, z ktorej výsledkov vznikajúce kvantové technológie čerpajú, vznikla ešte v devädesiatych rokoch minulého storočia. V roku 2000 prof. Vladimír Bužek založil na Fyzikálnom ústave SAV oddelenie Centrum pre výskum kvantovej informácie, ktoré sa venuje teoretickému vývoju kvantových technológií. Medzi desať najcitovanejších vedeckých prác z fyziky (vrátane publikácií z CERNu) na Slovensku patria práce prof. Bužeka o kvantovom klonovaní a kvantovom komunikačnom protokole “quantum secret sharing”. Dnes sa výskumníci centra sústreďujú na oblasť kvantových sietí, kvantovej výpočtovej zložitosti, kvantovej metrológie a vývoju efektívnych výpočtových nástrojov na simulovanie kvantových systémov. Matematický výskum v oblasti kvantových štruktúr a logík na Matematickom ústave SAV rozvíjal prof. Anatolij Dvurečenskij a jeho kolegovia ešte pred objavom ich potenciálu v informačných technológiách. Ich práce patria na Slovensku medzi tie najcitovanejšie v matematike. Experimentom v oblasti kvantového počítania sa venuje výskumný tím pod vedením prof. Miroslava Grajcara, ktorý, v spoločnom laboratóriu Fakulty Matematiky, Fyziky a Informatiky UK a Fyzikálneho ústavu SAV, pracuje na supravodivej implementácii kvantových bitov, s aplikáciami najmä v oblasti kvantových meraní a kvantovej optiky v mikrovlnom režime. Vývoj kvantových technológií priamo súvisí aj s materiálovým výskumom (realizáciou exotických systémov ako napr. Majoranovské fermióny), ktorý zastrešujú (celosvetovo) unikátne nízkoteplotné laboratóriá Ústavu experimentálnej fyziky SAV (prof. Peter Samuely) a Prírodovedeckej fakulty UPJŠ (prof. Alexander Feher) v Košiciach.

Optimal Port-based Teleportation in Arbitrary Dimension
Quantum teleportation is one of the earliest and most widely used primitives in Quantum Information Science which performs an arbitrary quantum state transfer between two spatially separated systems. It involves pre-sharing an entangled resource state and consists of three simple stages. The first stage involves a joint measurement of the teleported subsystem together with the share of the resource state on the sender’s side. In the second step, a classical measurement outcome is communicated to the receiver. The last step consists of applying a requisite correction operation which recovers the transmitted quantum state. Port-based teleportation (PBT) is a unique set of teleportation protocols in that they do not require unitary correction. We study PBT protocols and fully characterize their performance for arbitrary dimensions and number of ports. We find the optimal probability of success and the fidelity of teleportation for all probabilistic and deterministic PBT schemes. In the latter case, surprisingly, the answer depends only on the largest eigenvalue of a certain easy to construct a matrix which encodes the relationship between a set of Young diagrams and emerges as the optimal solution to the relevant semidefinite program. To derive our results, we develop new mathematical tools to study the symmetries of the operators that arise in PBT protocols and belong to the algebra of partially transposed permutation operators. These tools can be used to characterize quantum systems with partial symmetries. Quantum states occurring in the PBT protocol are one such example. Systems with partial symmetries are widespread but in contrast to their permutational-invariant counterparts very little is known about how to efficiently estimate their properties.

Time deformations of quantum master equations
Speaker: Sergey N. Filippov (Moscow)
Abstract: We subject convolutionless and convolution master equations to time deformations and explore properties of the modied maps. Positive and completely positive divisibility of the original dynamical map is related with positivity and complete positivity of the deformed map. We provide examples of time-local and convolution master equations for qubits to illustrate the results.

Quantum Technology Innitiative in Slovakia
Experts from academia (Prof. Vladimir Buzek, Prof. Peter Samuely, Prof. Alexander Feher, Vladimír Cambel, DrSc, Prof. Miroslav Grajcar, doc. Karol Nemoga, doc. Mário Ziman) have met with the representatives of Slovak Ministry of Education to discuss possibilities of the support for the development of quantum technology oriented research in Slovakia. This is the starting point of the National Quantum Technology Slovak National Initiative. Although no formal proposals have been made, the process of the formulation of the national platform has started. Let us stress that the existence of such national platform is necessary requirement for Slovak researchers to have access to European Quantum Flagship. Specialized research programs and invesments are already running in many European countries: United Kingdom (350 M£), Denmark (300 M€), Germany (300 M€), Netherlands (300 M€), Hungary (10 M€), etc. Even stronger quantum technology programs are in China, Japan, USA, Canada, Australia. Huge recent investments of Google and Microsoft in quantum technologies demonstrates that the field has really strong potential.

Quantum Technologies Flagship Final Report || pdf ||
To prepare the QT Flagship, the European Commission appointed an independent High-Level Steering Committee (HLSC) consisting of 12 distinguished Academic Members and 12 high-ranking Industry Members (from both large multi-nationals and SMEs), as well as one observer. One of the members of HLSC was Prof. Vladimír Bužek, founder of Research Center for Quantum Information at Institute of Physics of Slovak Academy of Sciences. After almost one year, on July 2017, HLSC presented their final report.
The Strategic Research Agenda (SRA) proposed in this document sets the ambitious but achievable goals for the Flagship’s ten-year lifetime, and details them for the initial threeyear ramp-up phase. To work towards these goals, the QT Flagship should be structured around four mission-driven research and innovation domains, representing the major applied areas in the field: Communication, Computation, Simulation, as well as Sensing and Metrology. These application domains should be built on a common basis of Basic Science, with top research institutions and companies spread across Europe assisting their objectives by delivering novel ideas, tools, methods and processes. The enabling aspects addressed in each domain belong to one of these three categories: Engineering and Control, Software and Theory, Education and Training.

Quantum Manifesto || pdf ||
Strategic document that calls upon Member States and the European Commission to launch a €1 billion Flagship-scale Initiative in Quantum Technology, preparing for a start in 2018 within the European H2020 research and innovation framework programme. It was prepared by Aymard de Touzalin (European Commission), Charles Marcus (University of Copenhagen), Freeke Heijman (NL ministry for economic affairs), Ignacio Cirac (Max-Planck Institute for Quantum Optics), Richard Murray (Innovate UK) and Tommaso Calarco (IQST Centre, Ulm) and officially released on May 2016 at the Quantum Europe Conference in Amsterdam in cooperation with the European Commission and the QuTech center in Delft. It aims to place Europe at the forefront of the second quantum revolution now unfolding worldwide, bringing transformative advances to science, industry and society. It will create new commercial opportunities addressing global challenges, provide strategic capabilities for security and seed as yet unimagined capabilities for the future. As is now happening around the world, developing Europe’s capabilities in quantum technologies will create a new knowledge-based industrial ecosystem, leading to long-term economic, scientific and societal benefits. It will result in a more sustainable, more productive, more entrepreneurial and more secure European Union. Quantum Manifesto was endorsed by more than 3500 researchers and initiated the Quantum Technology Flagship. The document was prepared under FP7 Coordination Action QUTE-EUROPE (http://qute-europe.eu/) that was coordinated by Research Center for Quantum Information of Institute of Physics of Slovak Academy of Sciences (Mário Ziman).
