Title: Quantum Information Science and Quantum Technologies at Quantum Optics Group at ICFO

Abstract:
In my talk I will give an overview of research lines in my group that belong to the Quantum Information area: 1) Detection and characterization of entanglement and Bell correlations in many body systems; 2) Quantum Simulators; 3) Quantum Thermodynamics; 4) Quantum Metrology and Estimation; 5) Interpreting Quantum Phenomena in Music. I focus on demand on those aspect that will be the most interesting for the audience.

Title: Properties of the asymptotic incompatibility measure in multiparameter quantum estimation

Abstract:
We address the use of asymptotic incompatibility (AI) to assess the quantumness of a multiparameter quantum statistical model. AI is a recently introduced measure which quantifies the difference between the Holevo and the SLD scalar bounds, and can be evaluated using only the symmetric logarithmic derivative (SLD) operators of the model. At first, we evaluate analytically the AI of the most general quantum statistical models involving two-level (qubit) and single-mode Gaussian continuous-variable quantum systems, and prove that AI is a simple monotonous function of the state purity. Then…. (attend the seminar to know the rest)

Title: Measurement-powered engine

Abstract:
In the quantum realm, irreversibility primarily comes from the measurement process. From a thermodynamical point of view, the latter plays a role similar to a hot source with the noticeable difference that, in this case, the fuel is not thermal but quantum. In this seminar, the concept of a measurement-fueled engine based on a single qubit will be introduced, revealing the energetic counterpart of measurement devices. Then, the measurement process will be described from a quantum perspective, considering the creation of quantum correlations between the system to measure and a quantum meter. Energy and entropy flow along this process will be studied, unveiling the microscopic origin of the measurement fuel, and proving that entanglement plays a crucial role in the fueling mechanism. These can be regarded as a new class of heat engines in which there is no thermal bath, and the only source of fuel and noise is the measurement itself.
