Online seminar #14: Magnetism in the 2D limit

Dorye L. Esteras (ICMol) The exfoliation of graphene down to the monolayer limit opened a new field of science based on infinitely thin materials. Encouraged by these findings, several efforts have been made in order to bring magnetism into the 2-dimensional (2D) limit. Despite the predictions of Mermin-Wagner theorem, these systems have magnetic order under…

Online seminar #11: QML for optimization via variational algorithms & coordinate transformations

Pablo Bermejo (DIPC-Multiverse Computing) We are currently experiencing the era of NISQ (Noise Intermediate Scale Quantum) devices. This means that there is still an uncertain near-term future for fields such as quantum computing, which completely relies on quantum hardware that is not yet capable of delivering the required performance to achieve game-changer applications. In spite…

Online Seminar #10: Variational waveguide-QED quantum simulators

Cristián Tabares (CSIC-IFF) Quantum computers and simulators are expected to provide new ways to study the properties ofcomplex quantum circuits. Since they are still prone to errors in the calculations, Variational Quantum Algorithms (VQAs) have emerged as a possible practical way to exploit current state-of-the-art quantum devices. These algorithms propose using a classical optimizer to…

Online Seminar #9: Spin qubits in quantum dots

Virginia N. Ciriano Tejel (Quantum motion) Silicon has become one of the leading platforms for quantum computation, having demonstrated qubits with long coherence times and high fidelity operations. Moreover, the similarities between silicon quantum dots and transistors give hope for mass production of qubits easily integrable with control electronics.  This seminar will go over the…

Online Seminar #8: Benchmarking the role of particle statistics in quantum reservoir computing

Guillem Llodrà (IFISC UIB-CSIC) Quantum reservoir computing is a neuro-inspired machine learning approach harnessingthe rich dynamics of quantum systems to solve temporal tasks. It has gathered attentionfor its suitability for NISQ devices, for easy and fast trainability, and for potentialquantum advantage. Although several types of systems have been proposed as quantumreservoirs, differences arising from particle…

Online Seminar #6: Quantum magnonic devices: a flexible tool for quantu technology

Carlos González-Ballestero (Institute of theoretical physics – U Insbruck) Despite its tremendous success, microwave-based quantum technology has limitations that couldbe solved by a hybrid approach, i. e. by interfacing microwaves with another degree of freedomwith complementary properties. Spin waves in ferromagnets, and their quanta magnons, are idealcandidates as they show tuneable spectrum and nonlinearity, have…

Online Seminar #5: Quantum-inspired solutions for privacy leaks in machine learning

Alejandro Pozas-Kerstjens (ICMAT) Vast amounts of data are routinely processed in machine learning pipelines, every time coveringmore aspects of our interactions with the world. However, the quest for performance is leavingother important aspects, such as privacy, on the side. For example, when the models processingthe data are made public, is the safety of the data…
