Abstract:

This project seeks to establish a radically new, alternative approach to realizing the fundamental building blocks of quantum computers with superconducting qubits. In the next 3 years, we plan to employ only a handful of realistic components to realize robust error-corrected logical quantum bits. We aim to demonstrate the same level of protection provided by a few hundreds of qubits (with properties beyond the state of the art) in today’s mainstream approach of the so-called surface code architecture. Our alternative approach is known as cat codes, because it employs multiple interconnected high coherence cavity modes with non-linear dissipation, to encode a qubit in superpositions of Schrödinger cat states. Our project combines realizing the quantum processor architecture as well as the control system and the protocols that drive it, building towards a full-stack error-corrected quantum computer. The partners in our collaboration form a strong synergetic group that has the full range of expertise needed to design and realize these systems, and to obtain these challenging goals. Furthermore, all partners of our project, including both industry and academia, have worked together and published works in the fields of quantum computing and quantum information processing.. We aim to implement error protected qubits, fault tolerant operations, and demonstrate the scalability of this approach by realizing a repetition code. Our project will enable quantum experiments towards the ambitious and well-defined goal of constructing a logical qubit, on which we can perform gates, and most importantly, quantum error-correctio (QEC). All algorithms with theoretically proven quantum speedup require QEC, therefore, with this project we are realizing an essential building block of a European error corrected quantum processor.

Abstract:

The main objective of our project is to develop a complex multiscale theoretical and experimental framework aimed identify the critical parameters and underlying physical mechanisms of the enhanced energetic efficiency skyrmion manipulation by electric field and spin currents in storage, synaptic and Qubit spintronic devices. Following the complex material issues, pointed out in the literature, we aim to investigate multilayer structures composed by a broad area of spintronic materials among the following classes: simple or complex metallic alloys, functional oxides (multiferroics), rare-earth based oxidic or non-oxidic structures. The main objective will be achieved following specific objectives: (O1) Theoretical predictive analysis of materials and multilayered architectures for PMA, DMI, Rashba intrinsic field anatomy, magnitude and voltage variation for skyrmionic applications controlled by electric field and spin-transfer-torque. (O2) Design of innovative experiments and spintronic devices architectures. (O3) Development of atomistic/micromagnetic models/simulations of the functional response and operating phase diagrams of realistic skyrmionic devices. (O4) Experimental realization and characterization of materials, nanostructures and voltage and spin-transfer torque controlled skyrmionic devices, for correlation with (feedback to) theory.

Abstract:

The main objective of the project is to obtain ferroelectric materials with controlled electronic properties at the same level as this properties are controlled in Si. This will be realized by hetero-valent doping, correlated with stress engineering and band gap engineering without affecting, as much as possible, the ferroelectric properties. The main objective is complex and ambitious because, up to date, there was no experimental demonstration that it possible to obtain n or/and p type conduction in epitaxial ferroelectrics. The successful achievement of this objective will open a new domain, that of ferroelectric electronics or ferrotronics, by producing electronic devices of p-n homo-junction type or junction transistors with ferroelectric materials. Two types of materials are envisaged, namely lead titanate-zirconate (PZT with tetragonal structure and a mixed bismuth ferrite (BFO) with bismuth chromit (BCO). In the first case the heterovalent doping will be studied on Pb or Zr/Ti sites with the aim to obtain n and p type conduction. The final goal is to produce a p-n homo-junction based on epitaxial PZT films. In the second case band gap engineering will be tested by varying the Fe/Cr content, and the dominant conduction mechanism will be identified, the goal being to use the material in photovoltaic applications. The activities will contain: theoretical studies regarding the relation between dopants, electronic properties and the ferroelectricity, including self-doping effects or electrostatic doping; target preparation for deposition of thin films; epitaxial growth of the film; characterization activities of the structure and physical properties. Not only classic doping in the target is envisaged but also doping during the epitaxial growth. The consortium is composed of 4 teams from three different institutions, including a number of 14 young researchers full time equivalent.

Abstract:

Quantum information and quantum technologies are at the forefront of the second quantum revolution: quantum computers, quantum cryptography, quantum communication, quantum imaging/sensing etc. Quantum technologies are strategically important for the economic development -- the European Union recently announced a 1 Billion Euro Quantum Technologies Flagship (QT Flagship) program. Compared to other European countries, unfortunately these fields are seriously underdeveloped in Romania.

The project aims to develop quantum information and quantum technologies in Romania, such that the Romanian community will actively participate in the QT Flagship. The project director (R.I.) is National Quantum Coordinator for Romania in the coordination and support action preparing the European QT Flagship.

The project has three strategic objectives:

(i) research: developing the research capacity in quantum information and quantum technologies;

(ii) education: teaching and training PhD students, postdocs and researchers to work in these fields;

(iii) dissemination: disseminate and transfer the results to society in order to stimulate scientific and economic progress.

Each partner will be responsible for a project from the common research agenda:

1. IFIN-HH: developing theoretical and computational methods for quantum information and quantum technologies (Q-INFO)

2. INFLPR: developing the integrated quantum photonics platform (Q-CHIP)

3. IMT: quantum information with optical vortices (Q-VORTEX)

4. UPB: developing two research laboratories and a quantum source (Q-LAB)

(a) quantum computation lab: cloud programming the IBM-Q quantum computer;

(b) applied quantum information lab.

5. INCDTIM: developing theoretical models for quantum computation with Majorana fermions (Q-FERMI)

The project will result in the formation of the Romanian Quantum Network and the participation of Romania to the European QT Flagship.

Abstract:

In this project, we will use our recently introduced guidance idea and the concept of band structure engineering in order to search for oxide and silicide materials with high thermoelectric (TE) efficiency as future advanced TE materials for the next generation of space TE generators. These generators need significant improvements in reliability, specific power by a factor of ~2-3, and TE efficiency by a factor of ~1.5-2.5 over the already used generators in the space missions. Employing complementary rational methods for fabrication, characterization and optimization of the theoretically predicted high performance TE materials, we will fabricate thin films and TE thermocouples based on these materials, characterize, and validate the high performance advanced TE materials.

Abstract:

The realization of efficient hydrogen storage in materials will have a tremendous impact on the fields of renewable energy and clean transportation. The most promising high uptake materials are based on the physisorbtion of the hydrogen which offers fast, reversible, energetically cheap storage. However, materials synthesized so far have poor ambient conditions performance due to the weak forces binding the molecular hydrogen. We will develop a universal multiscale simulation tool to aid the design of better hydrogen storage materials that will improve upon the state of the art simulations as follows. i) The polarization effects in electric fields will be included both at microscopic and macroscopic scales. ii) The weak interactions involved in the physisorbtion will be correctly treated at the ab initio level, thus revealing the most favorable microscopic features of the materials for hydrogen storage and ensuring the transferability of the code. iii) The simulation will be precise and transferable allowing in silico screening on a large class or materials, thus greatly reducing the experimental overhead. We aim to open the new research direction of electrically controlled hydrogen storage. We will design and then synthesize in the lab polarizable nanoporous materials with electrically tunable hydrogen storage properties based on covalent organic frameworks. We will assess the potential of these materials for industrial applications.

Abstract:

The aim of the present multidisciplinary project is to design by modeling&simulation, produce by innovative synthesis methods and various sintering strategies, to investigate the physico-chemical properties at various length scales of a few types of magnetoelectric composites with emergent properties in order to integrate them at industrial scale in a few types of new applications. Two types of devices based on magnetoelectric composites will be produced: (i) miniaturised magnetoelectric tunable reconfigurable antennas based on particulate ceramic composites; (ii) new types of sensors / transducers / actuators / harvesters based on layered magnetoelectric composites. The project will contribute to increase the consortium capacity to approach top research subjects in the field of smart multifunctional materials with high applicative potential. In terms of material science aspects, an important contribution will be given by a complex physico-chemical experimental – modeling approach for understanding the relationship between composition, micro/nanostructural parameters and functional properties of the magnetoelectric composites with different degrees of phase connectivity. The composition, phase interconnectivity and microstructures will be optimised and the best composite structures will be selected for the proposed applications. By considering the dielectric, ferro/piezoelectric and magnetoelectric properties of the produced composites, new magnetoelectric devices will be designed, realised, tested and optimised and the best solutions in terms of both technical parameters and cost efficiency will be implemented as prototypes by the industrial partner. The new devices are expected to contribute to the increase of the company performances by extending its production capacities, by extending the number of high specialised employees and the number of its beneficiaries. The overall scientific goal is to improve the knowledge in the field of multifunctional magnetoelectric composite structures at different levels (macroscopic, mesoscopic and at nanoscale) in order to generate properties beyond the present ones and to integrate them into new magnetoelectric devices with superior characteristics and low cost.
