Quantum corrector codes : controlling decoherence due to an arbitrary environment
Lecture
Event
The sixth lesson concluded the lecture with a brief overview of error-correcting code methods in quantum information ( 9th chapter). We began by summarizing the methods of decoherence control based on observation and manipulation of the environment, …

Energy is the major challenge facing humanity in the 21st century. The increase in the world's population, the economic growth of the planet's major countries, the programmed disappearance of non-renewable energy sources (oil, coal, gas and even uranium), …

Power and knowledge. The relationship between two kinds of uncertainty
Guest lecturer
Event
The old question about the relationship between knowledge and power, which goes back to the Platonic theory of the philosopher-king, has been translated in contemporary times into two figures that would represent the type of knowledge that should guide …

Oxygenic photosynthesis enables plants to use solar energy to reduce carbon dioxide and produce biomass. Some micro-algae or bacteria have even developed a variant of this process, enabling them to produce hydrogen thanks to a specific and highly …

Abstract In the second lesson, we first discussed a subtle dissipative mechanism that can affect Josephson junctions in a non-equilibrium situation, which is the parity defect of superconducting electrodes. If an insulated junction has an odd number of …

The water oxidation enzyme in the photosystem is largely responsible for converting solar energy into the high-energy chemical compounds needed to sustain life on the planet, and which have accumulated in the form of fossil fuels. This enzyme also …

This first lecture on molecular oxygen has laid a number of chemical foundations for the study of oxygen reactivity in biological systems. Oxygen arrived on earth in a way by accident, being the product of photosynthesis, which uses water as an electron …
