Θέμα: Superconducting Nickelates and Moving Towards Real-World Applications in Quantum Computing
Superconducting nickelates – The first observation of superconductivity at relatively high temperature in epitaxial thin films of infinite-layer (IL) nickelates was a significant breakthrough in the field of unconventional superconductivity (D. Li et al., Nature 572, 2019). This discovery, driven by the decades-long search of cuprate-like physics in other strongly correlated metallic oxides, generated intense interest. Further progress in the field crucially depends on the synthesis of high quality superconducting (SC) nickelate samples, which can provide reliable experimental data. However, their synthesis poses considerable challenges, largely hindering experimental research on this new class of oxide superconductors. That synthesis is achieved in a two-step process that yields the most thermodynamically stable perovskite phase first, then the IL phase by topotactic reduction, the quality of the starting phase playing a crucial role. We have recently accomplished the synthesis of SC IL praseodymium nickelate thin films (A. Gutiérrez-Llorente et al., Advanced Science 11, 2024). From these results, I will discuss the importance of the combined optimisation of both steps of the synthesis and analyse the transport properties of the incompletely reduced films, offering insight into the reduction process. These results contribute towards the goal of yielding high quality superconducting nickelate samples that could push forward experimental research on the field. Towards real-world applications of quantum computing – In the second part of the seminar, I will provide a balanced evaluation of the potential of quantum technology, focusing on the opportunities for computation offered by quantum mechanics. This will include a brief overview of the capabilities and limitations of quantum computers, an introduction to quantum computing platforms, namely, superconducting qubits, and an outlook on algorithms for quantum computers. The emphasis will be on the essentials rather than the details, which intends to be a useful starting point for interested students in science and engineering.

Πρωινή Διάλεξη:
Ώρα: 10:45–12:30
Θέμα: Quantum Computing and Algorithms (I)
This lecture aims to provide a comprehensive understanding of quantum computing's principles, its applications and its potential impact. What can we achieve with quantum computation? What are the advantages that a quantum computer might offer over classical computing? How is a quantum computer different? I will introduce the fundamental concepts of qubits, superposition and entanglement as well as the quantum circuit model, including quantum gates and circuits. Additionally, I will discuss the development of quantum algorithms and their applications, starting from the simpler examples and their practical implementation to foundational quantum algorithms for which there is a provable quantum speedup, such as Shor's Factoring Algorithm, Grover's Search Algorithm.

Ώρα: 12:45–14:30
Θέμα: Quantum Computing and Algorithms (II)
This lecture intends to provide a grasp of how advanced quantum algorithms work and an introduction of the current phase of quantum computing, usually denoted as the noisy intermediate scale quantum (NISQ) era. I will explore the potential of quantum algorithms specifically developed to be run on current quantum computing hardware, focusing on their potential to solve real-world problems and perform tasks that are challenging for classical computers.
